Looking for a cheap part-time or full-time business? Start a yacht and power paddler boat detailing business that can help you earn more money than your full-time job. If you live in a coastal city, this is the ideal business. Follow the advice below to be on your way to financial independence.
Fill out a business license application as required by federal, state and city laws.
Go to the Mobileworks website to get ideas on supplies and help with detailing resources. Purchase and gather all items listed in the "Things" section. Avoid buying used items; take advantage of manufacturers´ guarantees.

The present invention relates to the general field of inflatable boats, and more particularly it relates to improvements applied to inflating and/or deflating such boats when they include at least two inflatable chambers.

Although the invention relates to all types of inflatable chamber with which an inflatable boat might be equipped, it relates in more particularly advantageous manner to inflating and/or deflating the inflatable float(s) with which such  battery boats are equipped. For reasons of safety, such inflatable floats are subdivided by internal partitions into a plurality of compartments in such a manner that if one compartment should become deflated by accident, the other compartments are not affected and the boat continues to be buoyant.

Another drawback lies in the fact that the intercommunication valves are expensive devices. This equipment is therefore costly in an inflatable boat (which in practice can have as few as three or as many as seven or eight intercommunication valves depending on its dimensions and the number of compartments).

Yet another drawback lies in the fact that an intercommunication valve can be left in the open position (so that two adjacent compartments remain pneumatically interconnected) by inadvertence (closing forgotten, accidental opening), which can affect the buoyancy of the boat in the event of these compartments that have remained interconnected being deflated accidentally. This can become catastrophic if all of the intercommunication valves of a boat remain in the open position.

Set up pricing after investigating the competition. Offer a low monthly fee for detailing boats or yachts on a regular basis. Be flexible.
Place magnetic signs on your car doors or put stick-on vinyl letters containing company name and phone number on rear window.
Visit marinas and ask managers for referrals. Leave business cards to hand out to customers.Wait for customers to call. Avoid giving clients a bid without first seeing the condition of the boat or yacht.

The provisions in accordance with the invention make it possible in general to simplify and accelerate the operations of inflating and/or deflating electric inflatable boat of any type. However these provisions can also provide advantages in particular applications, some of which are being encountered with increasing frequency. Thus, these provisions can be advantageous with semi rigid boats that are housed in shelters on board large boats or yachts, since they can thus be housed with their floats in a deflated state: it then becomes possible to house a semi rigid boat of larger dimensions in a given shelter or to provide a shelter that is smaller for receiving a semi rigid boat of given dimensions. Another advantageous field of application lies in transporting semi rigid boats of great width which, by deflating their inflatable floats, can be loaded onto a road trailer and comply with highway loading gauges or on a railway car and comply with rail loading gauges.

Secure and store loose items. Ensure all windows and doors are tightly shut. Avoid getting water on cockpit electronics and inside cabin.Power wash boat from top to bottom with boat soap to rid boat of dirt and bugs. Pre-soak boat canvas in degreaser then use a brush to clean off dirt. Rinse with power washer.Use a hydrochloric acid solution to get barnacles and scum off the bottom of the boat. Follow instructions carefully this product is harmful to skin and painted surfaces. Rinse product off with power washer.Scrub the out side of the children battery boat or yacht with the large plastic brush. Rinse with plain water using the power washer.Polish chrome with metal polisher. Sand wood surfaces with 280 to 300 grit sandpaper; if worn, then oil.Clean glass surfaces with window cleaner.Put a light coat of wax on all painted surfaces and bottom of the boat. Let dry and use professional waxer to buff the boat or yacht.

The power of a kayaking comes from you and your paddle

by: fulong   Keywords: power, paddler, boat

This invention pertains to small keelless boats. Such boats, because they offer little resistance to leeway, cannot be sailed on the wind and canoes especially are difficult to paddle on a straight course, particularly by a single power paddler boat . Lee boards have been employed to minimize leeway in sailing canoes, but these have not been entirely satisfactory, among other reasons, because they often occupy valuable space in the vessel.

The power of a kayaking comes from you and your paddle. The different types of strokes take you where you want to go and can also save you from turning over or crashing into a rock. Practice with your paddle until it feels natural and you'll be a natural on the water.

Work on your strokes in calm water, so that you can concentrate on the proper execution of the strokes with the paddle. Sit in the kayak all the way back in the seat with knees slightly bent.
FIG. 1 is an elevation view showing one embodiment of the invention applied to a canoe.

FIG. 2 is a bottom plan view of the same canoe showing, in broken lines, an assymetric placement of the keel, for example, to correct the assymetric thrust of a single paddler boat .

FIG. 3 is a cross sectional view taken at plane 3--3 of FIG. 1 showing an arrangement of keel, flexible bracket and strap in accordance with the invention.

FIG. 4 shows the features of FIG. 3 in greater detail and, in broken lines, demonstrates sidewise displacement of the keel by elastic bending of the bracket as would occur, for example, on collision with an underwater object. Especially when double keels are employed as shown in FIG. 7, the bracket may be so selected as to deploy the keel outward to as much as about 45° from vertical. In a double keel embodiment as described, the keel shown in broken line in FIG. 4 would represent the starboard keel. Double keels may thus be splayed outward making easier the beaching of the boat.

FIG. 5 is a cross sectional view taken at plane 5--5 of FIG. 1 showing one means for securing a strap to the boat above water line 11.

FIG. 6 shows the features of FIG. 5 in top plan view.
Hold your power paddler boats with your hands an equal distance apart and from each end. It helps to imagine dividing the paddle in thirds, with your hands placed one third of the way from each end. You can also hold the paddle centered in front of you with your arms bent at a 90-degree angle; that will give you the correct spacing.
Make the common stroke with your paddle, the forward power stroke, by leaning forward to put the paddle in the water near your toes. Pull the blade straight back along the boat until it reaches your hip. Lift the paddle, and repeat on the other side.

The arrangement of elements are here described results in the single-keel configuration of FIG. 3 wherein the bow or stern sections are shown as items 18. The invention is not limited, however, to embodiments comprising a single keel. Using the same materials and methods, two parallel keels 12B can be provided as illustrated in FIG. 7. Furthermore, the double keels 12B may be oriented outwardly as shown in FIG. 4 in broken line such that keels makes an angle with the vertical of about 45°. This embodiment, which is comprised in claims has distinct advantage to the boatman who must beach his boat from time to time.

In some cases it may be useful, for example on flat bottom motor powered boats, to use more than two keels, possibly as many as five.

The electric inflatable boat in say a white water canoe normally maintains a straight course only with expenditure of considerable effort because of windage on the freeboard and unsymmetrical thrust from the single paddle. FIG. 2 illustrates a strategy; for overcoming this problem wherein the keel itself counteracts the forces causing the canoe to go off course. In the embodiment of FIG. 2, the canoeist has displaced the forward and aft straps. He could also achieve similar effect by displacing only the forward strap and bending the keel.

The keels are removed by reversal of the installation process.
Turn the kayak with a sweep stroke. Allow your paddle blade to arc away from the boat with the face of the blade addressing the water. This swings the bow of the boat in the opposite direction from the paddle blade.Practice the reverse sweep by making two strokes on the same side; first a power stroke, and then a sweep to turn the kayak in the opposite direction.
Correct steering when needed with the stern rudder. Place the power paddler boat  in the water near your hips, which drags the boat. Try not to use this stroke when surrounded by lots of waves.

Playing a power paddler boat

by: fulong   Keywords: power, paddler, boat

Various proposals have been made to provide portable collapsible boats, ranging from rigid hull boats having detachable hull sections to flexible hull

 power paddler boat   having a complete take-apart skeleton frame with removable skin. Both types of proposals have significant disadvantages.

Conventional collapsible boats having rigid hulls rely on two or more rigid hull sections that couple or connect to form a boat. Collapsible boats having rigid hulls are durable, lightweight and stiff, but they either take up a significant amount of space when disassembled if the parts do not ???nest??? within each other, or they are severely constrained in their shape if the parts do nest within each other.

Conventional collapsible boats having flexible hulls incorporate a skin-on-frame construction comprising a frame used to form the outer shape of the hull and an impermeable skin stretched over the frame. Some of the better known types are assembled from a plurality of disconnected stringers and frames which are joined together to form a relatively loose framework. The skin is usually a one piece skin having bow and stem-shaped pockets. The skin receives two halves of the framework, which are then rigidly coupled or connected together inside the skin.

While portable collapsible electric inflatable boats having flexible hulls require little storage space and are easily transportable when collapsed, they suffer from several disadvantages. The skin-on-frame construction of flexible hull boats is disadvantageous because:

    *
          o significant time and effort is required for assembly,
          o structure lacks rigidity, resulting in poor performance,
          o skin is fragile, particularly in the area where the operator's weight is concentrated,
          o internal parts such as foot braces, seats, and padding are difficult to affix to the inside of the boat's flexible hull,
          o extra equipment is required to convert the boat to sail, rather than paddle use,
          o design lacks flexibility to accommodate both a single operator configuration and a multiple operator configuration,
          o the overall weight is greater than that of rigid boats of the same type and size.

Thus, there is a need for a portable collapsible paddler boat that requires little storage space, is light in weight, is easy to assemble and disassemble, has good structural rigidity, is durable and performs well.

To Paddle a Kayak Straight:
1.Ok, first things first. You need to be in the "Proper paddling position" when you paddle, so you need to be sitting upright and slightly forward in your kayak, your knees should be slightly bent with the balls of your feet (just below the toes) on the foot brace in the kayak, somewhat snug, forget about the seat back, you will have plenty of time to "sit back" and enjoy the view later.
2.Remember these few rules when trying to paddle in a straight line;

1. Always put the whole paddle blade in the water when you stroke.
2. When paddling the kayak forward, the paddle should never go past your seat when you execute the stroke, when you turn or compensate the kayak would be the only time you should be paddling past the seat or "Pivot Point" (You)
3. Easy does it! The kayak can only go so fast and turn so quickly, so execute your strokes with less speed and more precise power.

Try to visualize that you are pulling the boat to the paddle, not pulling the paddle to make the boat go. Pretend that when you "plant" the paddle in the water that in is now stuck in solid cement and cannot be moved so you will need to pull the power paddler boats towards the paddle
This mindset will allow for proper skill building that will eventually become part of your paddling skill inventory.

The invention relates to a boat that combines the best features of rigid hull boats with the best features of flexible hull boats without suffering from the drawbacks of rigid boats or folding boats. The present invention is easy to assemble and transport, lightweight, durable and rigid. Furthermore, the boat in accordance with the present invention easily adapts from paddling to sailing use and easily adapts from a single to a multiple passenger configuration.

The present invention is a boat comprised of a plurality of sections constructed of different materials. The boat is comprised of one or more rigid cockpit sections fastened, connected, or coupled together, with the bow and stem sections fastened, connected, or coupled to the rigid cockpit section. The rigid cockpit section is constructed from materials such as plastic, fiberglass, carbon fiber, or wood. The bow and stem sections have flexible hulls of a skin-on-frame construction.

The electric inflatable boat of the present invention comprises one or more rigid cockpit sections that may be fastened together by conventional mechanical means such as bolts or draw latches. In the preferred embodiment, the cockpit sections are detachably fastened together to provide versatility in the configuration of the rigid cockpit section. The cockpit sections are comprised of a rigid hull and rigid bulkheads, constructed of materials such as fiberglass, carbon fiber, plastic or wood. The bulkheads at the end of the cockpit sections form separate compartments with respect to the other sections of the boat and prevent water from entering the bow or stem sections in the event of a capsize, making the boat more seaworthy. The bulkheads also obviate the need for a watertight connection between sections.

In the present invention, the bow and stem sections are operatively connected to the rigid cockpit section. The connection of the bow and stem sections to the rigid cockpit section may be fixed or detachable. In the preferred embodiment, the bow and stem sections are detachably connected to the rigid cockpit section so that storage and transport are improved.

How to play in a zorb ball?

by: fulong   Keywords: zorb, ball

The present invention is directed to a device for supporting a water walking ball on a fluid stream, such as water, for use as an amusement or game playing apparatus. In its preferred application, the present invention is used as a "baseball" type game. Because of the use of flowing streams of water, the present invention is particularly enjoyable in hot weather and hot climates.

In the past, several devices have been used to support a ball or other object on a flowing fluid stream. In Neveling, U.S. Pat. No. 2,785,895, a toy fountain is described in which a light weight ball is held in a suspended spinning position at the side of a stream of water. In Neveling, a stream of water is generated in an elongated clear vertical member so that the supported ball may be viewed easily while limiting access to the ball.

Damm, U.S. Pat. No. 755,114 is directed to a fountain utilizing mercury as the liquid medium and illustrates the supporting of the ball on a vertical stream of mercury.

Stanley, U.S. Pat. No. 4,205,785 is directed to a water play toy in which a clown's hat comprising an inverted funnel with an impeller disposed in the top portion thereof is supported on a vertical stream of water and throws off a shower of droplets.

Evans, U.S. Pat. No. 3297324 illustrates the use of an air stream to support a light weight ball.

The present invention provides a water toy combining the well known participatory enjoyment of baseball with the cooling of water and water sprays.

In another aspect, the present invention provides a stationary base member for projecting a substantially laminar stream of water upward for supporting a zorb ball . An adjustable valve is connected to a water supply means for controlling the pressure of the laminar output stream of the base member and correspondingly controlling the supportive height of the toy ball.

In still another aspect of the invention, the supporting stream of water may be used as a "tee" where upon the player may strike the ball from the "tee" with a toy bat. When striking the ball, a spray of water is produced adding the aspect of water play to the game.

In yet another aspect of the present invention, a controllable valve is provided where upon a player may adjust the height of the supporting stream so as to make it more difficult for a second player to strike the toy ball with a toy bat. In this manner, a game of water baseball may be enjoyed wherein the player controlling the valve is the "pitcher" and pitches to the batter by adjusting the height of the toy ball supported on the stream.

 

 

 

 

 

 

To play in a zorb ball :
1.These inflatable Zorbs are 10 feet in diameter and weigh about 200 pounds. There is an outer layer (with massive air cushions) and an inner layer. Once you settle into the inner layer, you are securely strapped in. With a push, down the hill you go - summer salting along the way without ever touching the ground. And you don't have to go alone; a friend can be strapped in opposite from you. Knolls are enough for some; the steep hills are not for the faint-of-heart.

2.For the real dare-devils, try a Zorb ride standing up, hanging onto the sides (no safety straps). Also, if the day is a hot one, a bucket of water can be thrown in the inner layer, sloshing along with you as you roll.
3.You can also walk on water in a Zorb. These balls are smaller and have just one layer. A person steps into it before it is inflated. Once the ball has been inflated and sealed, walk or run across the water.

The present invention comprises a base coupled to a water source, the base outputting a stream of water for supporting a toy ball in mid air. The base includes filtering means for substantially eliminating turbulence from the water stream so that it is substantially laminar. The laminar flowing stream contacts a water roller and lifts it into a position of equilibrium where the upward force of the stream balances the downward force of gravity acting on the ball so that the ball is suspended in mid air. The flowing water clings to the surface of the ball and generates a force tending to center the ball in this supporting stream. If the ball becomes off center, an unequal force on the side of the ball furthest from the center of the stream will force the ball back to the stream center.

An open basket is coupled to the base and includes an opening in the center thereof for passage of the supporting stream. If the stream is interrupted, dropping the ball, or if the ball is otherwise caused to fall off the supporting stream, it will generally be caught in the basket and then roll to the center thereof, in proper position for lifting by the supporting stream. The basket comprises an open structure so that water does not collect in the basket but rather falls through to the ground.

A valve device is coupled to the base through a hose and is used to interrupt the flow of water from the water source to the base, correspondingly controlling the supporting stream. The valve may be spring biased so that it is in either the on or off position when at rest. By activating the valve, the presence and/or height of the supporting stream may be controlled.

A toy bat may be utilized to strike the ball from the supporting stream of water as if from a "tee". In this manner, the device of the present invention may be utilized in a game of "baseball". By manipulating the valve means, a "pitcher" may control the height of the supporting stream, making the zorb balls more difficult to hit by a batter.

An integrally constructed kayak paddle comprising

by: fulong   Keywords: power, paddler, boat

An improved kayak paddle for recreational or competitive paddling, which has handles affixed perpendicular to the shaft or shafts, which handles rotate on axles as the paddle is used, to reduce twisting of the wrists and other joints of the paddler and improve efficiency and comfort. The shape of the paddle blades is such that water falls off the corner of the blades and does not run down the shaft to wet the hands of the power paddler boat .

An integrally constructed kayak paddle comprising:

(a) a first paddle blade shaped with an acute angle or small radius at the lower interior corner thereof for assuring that water will collect at the lower interior corner and fall off from the corner instead of running down the shaft;

(b) a second paddle blade shaped with an acute angle or small radius at the lower interior corner thereof for assuring that water will collect at the lower interior corner and fall off from the corner instead of running down the shaft, oriented in the same plane;

(c) an upper shaft connecting the first paddle blade and the second paddle blade;

(d) a lower shaft connecting the first paddle blade and the second paddle blade;

(e) a handle to be held in the left hand of the power paddler boats which runs between and is connected to the upper shaft and lower shaft perpendicular to the axes of the shafts and resides on an axle which allows it to rotate in place as the paddle is used;

 

 

 

 

 

 

(f) a handle to be held in the right hand of the paddler which runs between and is connected to the upper shaft and lower shaft perpendicular to the axes of the shafts and resides on an axle which allows it to rotate in place as the paddle is used.

An integrally constructed kayak paddle comprising:

(a) a first paddle blade shaped with an acute angle or small radius at the lower interior corner thereof for assuring that water will collect at the lower interior corner and fall off from the corner instead of running down the shaft;

(b) a second paddle blade shaped with an acute angle or small radius at the lower interior corner thereof for assuring that water will collect at the lower interior corner and fall off from the corner instead of running down the shaft, oriented in the same plane;

(c) a shaft connecting the first electric inflatable boat and the second paddle blade, which has a U-shaped or V-shaped cross section of varying dimensions, with the largest dimension being large enough to allow handles to be affixed to the sides thereof; and the smallest dimension being only large enough to provide adequate support for the paddle blades;

(d) a handle to be held in the left hand of the paddler which runs between and is connected to the upper and lower edges of the shaft perpendicular to the axis of the shaft and resides on an axle which allows it to rotate in place as the paddle is used;

(f) a handle to be held in the right hand of the paddler which runs between and is connected to the upper and lower edges of the shaft perpendicular to the axis of the shaft and resides on an axle which allows it to rotate in place as the paddle is used.

Kayak paddles have been known for many years. Such devices have consisted of a single elongated shaft and two flattened blade portions, which may be either integral with the shaft or attached thereto. On some paddles the blades are feathered, meaning the planes of the blades are oriented in perpendicular or nearly perpendicular relation to each other, while on non-feathered paddles the blades reside in the same plane. The paddle is usually made of some suitably rigid material such as wood, aluminum, plastic, or the like. Light weight and strength to resist the forces imposed upon them are important considerations in the manufacture of electric inflatable boats .

In using a traditional kayak paddle one grips the shaft with both hands, parallel to the longitudinal axis. The blade is inserted in the water near the side of the boat at a point in front of the user. The blade is then pulled backward approximately parallel to the boat, by backward pressure exerted through the hand closest to the blade in the water, while forward pressure is exerted through the other hand. When the blade has been pulled back to a point beside or just behind the user, it is removed from the water with an upward motion and the opposite blade is inserted in the water in front of the user. The sequence of motions is repeated, creating forces which propel the boat forward through the water. Subtle differences in the amount of force applied and the direction in which it is applied with each stroke are used to steer the boat and keep it on course.

As the sequence of motions is repeated, particularly with feathered blades, the paddle is twisted and rotated between insertions of blades in the water to optimize the angle for exertion of force. This causes the paddle to slip in the hands of the user, which can cause irritation and blistering, particularly in the area between the thumb and forefinger. It also forces the wrist and elbow to flex with each stroke, which causes stress in these joints. The overall result of the twisting and rotating of the power paddler boat is a gradual loss of efficiency in paddling as fatigue and soreness increase.

As noted above, both hands are placed on the shaft parallel with the longitudinal axis when using a traditional kayak paddle. There is no perpendicular handle as there would be with a typical canoe paddle. It is recognized that the perpendicular handle is of substantial assistance to the canoe paddler, allowing him to apply force more efficiently with each stroke.

On a few kayak paddles, two handles are set approximately perpendicular to the axis of the shaft. This gives the paddler something comparable to the perpendicular handle on a canoe paddle, allowing him to make more powerful and efficient strokes. This was a significant feature in U.S. Pat. No. 4,673,361 to Harvey, Jun. 16, 1987. However, since the handles on these kayak paddles are fixed, they do not reduce the amount of twisting and turning of the wrists required with each stroke.

When traditional kayak power paddler boats are used, water tends to run down the shaft from the blade that is elevated at a particular moment and wet the hands of the paddler. This is sometimes prevented by using drip rings made of rubber or similar materials, which encircle the paddle shaft and deflect the water. Drip rings are typically an extra feature and add weight to the paddle.

The inflatable water toy may be used at least two different ways. In a first position, the bottom of the base for the inflatable water toy is positioned against the water, and the legs extend upward and curl downward so that the ends of the legs touch the water. One or more people may float on top of the base, or hang onto the legs. In a second position, the inflatable water toy is turned upside down so that the top of the base is in contact with the water, and the tips of the legs extend upwards. Each of the legs thus forms a saddle in which a lightweight user may sit, and the base extends like a table top between the saddles provided by the legs. The inflatable water toys may be used in a similar manner on land, with users situated between legs and the base serving as a table.

If you just want to look like you're walking on water, you can do it through illusion. All you need is a very thin layer of water over something solid. If the light's right the water won't be transparent and you'll appear to be walking on it. Platform shoes will help with the illusion. If you want it to be especially impressive and deal with transparent water, use something strong and transparent just below the surface.
