How To Buy An Inflatable Boat
An electric inflatable boat is provided with a multi-keel by having an inflatable
member or members constrained to lie between the flexible skin of the boat and a reaction surface. Preferably there is a rigid deck as a reaction surface overlying the flexible skin with two parallel inflatable tubes under the deck spaced apart by a distance equal to half the width of the deck. In a load carrying inflatable boat for carrying a plurality of passengers having a flexible underwater skin, a reaction surface overlying said skin and an inflatable former lying between the said skin and the said reaction surface and cooperating therewith to form a keel for the boat, the improvement consisting of having one or more inflatable formers adapted to cooperate with the said reaction surface and the said skin to form when inflated at least two spaced apart keels for the boat on respective sides of the centreline of the boat and providing between them a channel of the skin centred on the centreline of the boat and having a profile varying with the loading of the reaction surface to provide a self-compensating underwater surface for the boat which surface adapts itself to the planing characteristics required for different loads, the cross-section of the undersurfaces formed by said skin being substantially constant along the length of the keels when said members are inflated.An inflatable boat is not only a lot of fun, but also handy, whether you're trolling around a lake or docked at a mooring and want to get to shore. Here's how to buy an electric inflatable boat .Check out your local boat store. West Marine is a nationwide chain, but there are probably others in your area as well. All boating stores sell inflatables. Also, stores like Target, Wal-Mart and K-Mart have moved into the inflatable boat market as well.
This invention relates to inflatable boats, that is boats having inflatable flotation members, and is concerned with the keel arrangements of such boats. There have been numerous prior proposals relating to the underwater surface of inflatable boats, and it has also been suggested that for rigid-hull boats multi-keel underwater surfaces should be provided. Thus in British Pat. No. 1,273,692 there is disclosed a boat hull provided in a forward section with a twin keel and in a rearward section with a single keel. The forward twin keels may each be lowerable or raisable to improve riding characteristics of the hull.
In British Pat. No. 1,319,072 there is disclosed a power paddler boat in which the shape of the hull is a function of the hull construction itself of a number of inflatable tubes which cooperate to provide a generally U-shaped or V-shaped cross-section for the hull.
In British Pat. No. 1,362,677 there is disclosed an inflatable boat having inflatable side walls serving as floatation members, a flexible underwater skin, a rigid deck and between said skin and deck an inflatable former member along the longitudinal centre-line of the boat shaping the flexible skin to form a central keel.
However in none of these prior art proposals has it been appreciated or suggested that by having a boat with a flexible underwater skin and inflatable former members to cause the undersea surface of the boat to have a multi-keel construction, automatic adaptation of the planing characteristics of the boat to the load carried in the boat could be achieved. Peruse tag sales for an inflatable boat. This seems like an effort, but with the web it has become much easier. Check out craigslist or other community sites for information on upcoming tag sales. There people will list the valuable items they have for sale. If someone is selling an electric inflatable boat , contact them and arrange to check it out.
The present invention is concerned to form, by inflation, a multi-keel underwater surface. The proposal uses the flexiblity of a fabric skin, stretched over shaped inflated formers, to allow inherently the adaptation of the shape of the underwater surface to load conditions being experienced. This gives a self-compensating underwater surface which retains its good planing performance under all load conditions. The use of parallel twin inflated formers (preferably separate sacs or tubes) to give a generally W-section underwater surface is simplest and at the same time yields very good results. The spacing apart of the parallel formers may be 50% of the deck width of the boat.
The floor will provide the reaction surface against which the formers act and will most conveniently be rigid panels extending the whole width of the boat and terminating under, and being supported by, the inflated buoyancy tubes of the boat.
Boats thus constructed may be of any appropriate size but especially suitable will be application of this invention to boats of larger sizes, e.g. 7 meters length upwards, whether with single or multiple engine installations. On these sites you'll be able to get great deals with deep discounts either by bidding, as on ebay, or purchasing from a direct manufacturer such as Ambition Inflatables.Take a spin by your local marina. Not only do they have slips for you to buy, but they sell boats, too. And since most people who have a larger water craft need a kid power paddler boat chances are they will carry them as well. You might also get a great deal, as they are looking to make their money on the big-ticket gigantic boats and care less about the small profit margin for an inflatable boat.
