Every time we go camping at Clear Lake near Mount Hood in Oregon, I used to jealously walk past all of the canoes, kayaks and rowboats dotting the shoreline of the lake, waiting to be taken out into the water for hours of fishing and paddle-borne awesomeness.
We currently have a small Honda CR-V, and I just couldn’t imagine pulling a full-size boat on a trailer with it, so the idea of a small boat that I could transport on top of it was very attractive.
So, being that I also love to experiment with projects outside of my comfort zone, I started to imagine building a small plywood boat that I could then fiberglass and make seaworthy, or, I mean lakeworthy.
After researching several videos and websites (Hannu’s Boatyard is a classic website and the Kentucky Department of Fish and Wildlife have an excellent instructional Youtube video), I decided to try and make my own 2 sheet plywood boat. So, with most of the thoughts and plans in my head, I quickly sketched a basic layout of the boat on a piece of paper and went to the lumber yard.
Seriously, this homemade boat CAN be made with only two sheets of plywood, some fiberglass cloth and polyester resin (you can also use epoxy), screws, bondo, and paint, and will only cost you approximately $150 in materials.

We love inflatable boats, and LIBERTY BOATS has offered a variety of inflatable boats over the years. How do you select the boat that best meets your requirements with so many available choices? An inflatable's floor construction is the key to the trade-off between portability-ease of assembly and compact storage-and the rigidity needed for best performance. Sportboats are inflatables with a removable rigid floor system made from plywood, composite plastic or aluminum. Take a sportboat and trade the aluminum floor for a high-pressure inflatable floor, and you have an HP Inflatable Floor boat (sometimes called an Airfloor boat), combining the performance of a sportboat with the light weight and compact stowage of a soft stern dinghy.
HP-V floors perform more like a RIB, with one'piece (non-removable floor) configuration-the simplest high-pressure rollups ever developed.
LIBERTY BOATS stocks a full range of RIB boats in many different sizes & configurations.
Compact RIBs have a hinged folding transom, which allows the boat to be stored in much less space, and are super portable-we're talking roof rack to water in just 10 minutes! Take a flat-bottomed sportboat, and add two wedge-shaped sponsons constructed with high-pressure tubes and custom'molded high-density rubber. Added benefits of the tunnel hull design include higher efficiency at speed (smaller engines, less fuel), precise maneuvering in reverse (very unusual for most inflatable boats), and the ability to row effectively. The location where you intend to use your boat is the primary factor in deciding which hull fabric to choose. Construction of PVC and Hypalon boats is often different, too, but both are utterly reliable in use. Hypalon inflatables (and some PVC boats) are glued together using high-strength, two-part adhesives. Talk to most experts and they'll agree; the most common cause of premature inflatable boat failure is exposure to the sun. We believe customers buy smaller boats so they can leave them inflated and stored on deck or a swim step, or for ease of carrying to a car or cabin.
Make sure that you carry some basic safety gear aboard your inflatable when you go exploring.
I've been experimenting with using a high temperature, two part silicone as the mold material. Location: New York Is this the stuff that is used to cast a wax pattern that is then used in ?lost wax casting? in green sand?

I've carved a male pattern, from wood, to a shape which feels nice and should pop out nicely from the mold.
Location: California Save you some time Well as you know, I am sure, Lead BEGINS to melt at 620 F.

I tried using some of the one part high temperature RTV stuff, which cures on exposure to the moisture in air.
Location: New York When I was a teenager and could not purchase ducks (no money) I made a pattern from wood and then made a mold from plaster of paris. As far as I know the only silicone that is used in casting is to make a mold for wax copies that are then used in the lost wax process. Originally Posted by Robert Gainer When I was a teenager and could not purchase ducks (no money) Same thing, i pored lead into tuna cans, drove in a nail through the side.
Made my own scuba weights the same way, bolt on type, but then started with plaster molds to get a nice copy of one I bought.

Location: New York Just wondering if the production is up and running and if I can make a purchase. You can definitely start with only 6 spline weights and gradually acquire more weights later. If you end up doing a lot of manual lines fairing the ideal number of spline weights is 12; though, I actually have 18 spline weights.
In Westlawn all is clearly explained in detail and they have 2 blueprint for making your own cheaply but I dont think I have permission to post does two attachment sorry. When making potentially dangerous or financial decisions, always employ and consult appropriate professionals. Import charges previously quoted are subject to change if you increase you maximum bid amount. Our lineup features an assortment of both small and larger boats, with high-buoyancy tubes (so they can handle the extra weight of modern 4-stroke outboards), and enhanced cargo-carrying capacity. A rigid deep-V hull made from composite plastic, fiberglass or aluminum-a Rigid Inflatable Boat-is an efficient high-performance planing hull, but RIBs often must be stored on a trailer or set of hanging davits. They are best suited for beach fun and short-range exploring in protected waters, fresh water fishing or camping. The floor assembly is made stiffer with the addition of stringers, which run fore and aft to hold the floorboards in alignment, and aluminum extrusions to hold the edges in position.
Its special high-pressure inflatable floor (pumped up to 11psi) is substantially lighter and when deflated, can be rolled up right inside the boat. A further evolution of the HP Inflatable concept, HP-V floors dispense with sausage-shaped inflatable keels.
Cargo is located further down than in a flat-floored boat, and the low center of gravity provides stability comparable to a RIB hull design.
Their fiberglass hulls carve turns and cut through chop like conventional boats and shrug off abrasion from cruising gear, sand and gravel, dive tanks, etc. The hull is made from either fiberglass or RIMTEC injection-molded polyester, and has a shallow V-shape.
These rescue craft could hit speeds up to 65 mph, and handle extremely rough seas and breaking waves.
The resulting tunnel hull creates lift for efficient planing and also provides a cushion of air for a smoother, high-speed ride.
The choices are PVC coated polyurethane cloth, represented by most of our Inflatable boats, or Orca 820 Hypalon (neoprene-coated nylon).
Usually the difference is obvious on bargain boats, but inexperienced buyers don't realize how big an impact inferior fittings have until they actually use the boat. Fading, discoloration, fabric breakdown and damage to painted and varnished components can all be attributed to UV exposure.
We see dozens of inflatables rotting in the sun in our local harbor, and it isn't because they're being used every day. In addition to blocking UV radiation, covers also protect your boat from accumulated dirt, bird droppings and standing water. And we understand that many of our customers have smaller boats and generally have only two people to transport in their dinghy. Simply pick the combination of portability and performance that your boating style requires and choose the fabric best suited to your boating environment. It would hold up for five or six pours and then I would make a new mold from the wood pattern.
You need green sand to pack around the wax master and then all you do is add a hole to the green sand for adding the lead and a second hole to let out the air and steam. These days, however, I no longer need more than 12, as large hand-faired drawings?are now done, instead, in a hull-fairing program. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable.
On the other hand, if you enjoy .You Can Easily Build Your Own Boat With The Right Wooden Boat Plans . Boats with more flexible fabric floors fold to a light, compact shape, but their flexibility extracts a performance penalty. Floors use wooden slats enclosed in fabric pockets, and you don't need to remove them for storage.
With the floorboards assembled and the port and starboard hull chambers and small tapered keel tube inflated, the boat's floor fabric is stretched taut and takes on a shallow V-shape.
We have been astounded at how quickly inflatable floor boats jump on plane, and the fine performance they achieve using only a small outboard, thanks to their low weight. But unlike conventional boats, the addition of inflatable tubes to the topsides makes them more stable, more buoyant and less likely to scar the topsides of other vessels when used as a tender. Sport Cats are raced as two-person one-design ZapCats in the UK and Europe, as ThunderCats in South Africa, New Zealand and Australia, and in the U.S.
Also, since the PVC coating is more airtight than Hypalon, inflation pressure doesn't need to be topped off as with Hypalon boats.

We fit excellent accessories like stainless towing eyes, strong aluminum oars, reliable inflation valves and heavy-duty pumps to help you inflate your boat quickly with minimal effort. The differences between an 8'6" sportboat and a 10' sportboat in handling, carrying capacity and ride, due to the small surface area of the small boat hulls, are greater than you can imagine until you actually try them side-by-side.
Their modest cost is rapidly repaid by extending the life and the increased resale value of your boat.
If you are short of storage space or transport just you and your spouse, then an 8' boat may be just the ticket. You can pour begining at around 700F but the results arent pretty on a consistent basis Well, that's why I say we'll see how it all turns out. The only problem I found was that you needed to dry the plaster mold in an oven or the molten lead would make so much steam that the mold would break when you did the first pour. Every single painted spline weight I?ve worked with eventually had the paint chip and wear off. In fact, you can usually use a couple of heavy books, or mugs or cups filled with scrap bolts, or similar, at the spline's ends to make up 2 extra weights?effectively 8. If you want your boat to plane, allowing you to exceed 5 mph, a semi-rigid floor is required.
This enables the boat to ride through chop and track in turns better than a flat-bottomed boat.
The boats flex just enough to absorb wakes and waves that would threaten to throw you out of a hard-bottomed boat.
A flexible fabric hinge connects the floor to the transom, allowing the transom to fold flat when stored.
As a result, the boat can perform extremely tight turns, even at high speed (a Sport Cat can reportedly pull 2 Gs of cornering force!). But if you will do most of your boating in tropical conditions, a Hypalon boat will last longer because of its better resistance to UV degradation. A sportboat less than 9' long is capable of planing, but tends to be squirrely on the water, and will fall off a plane easily. But in our experience customers rarely come back wishing they'd bought a smaller boat, while the reverse is all too frequent. When all is said and done, it may be the boat you remember most fondly for its amazing versatility. See the Student Guide 2nd Edition, Section 9, starting on page 125 (particularly the bottom of page 127).
The floor also makes sportboats heavier than dinghies, but these boats are fast and lively with outboards from 2-50hp and offer a great performance for the price. Slightly less expensive than conventional sportboats, HP floor boats are a brilliant combination of benefits, not a compromise. The hulls cannot be disassembled, and therefore you can't stow your RIB in a bag in the lazarette. A large zippered bag is included for storage, and the stowed boat looks like a giant surfboard in a travel bag.
10' boats (and especially 11' boats) have less bow rise when they accelerate and will stay on plane at lower speeds.
Shifing some weights around to draw a complete line will also effectively increase the number of weghts; a passable work-around. Their flat bottoms and small engines (up to 4HP) make their performance non-planing,  with very poor directional stability (tracking) due to the lack of a keel thus limiting their range to in-harbor, relatively flat-water travel. You can deflate the tubes and stow the boat on deck in far less room than the inflated boat, but it still takes up space. While still large, the Compact RIB will fit on a foredeck or under a boom much more compactly than a normal RIB. They are less sensitive to steering inputs so you can relax more while driving them and their larger tubes with slightly greater freeboard will give you a drier ride.
These are marvelous because they are lightweight and plane easily with engines from 4hp to 15hp.
Therefore, we generally recommend RIB's for owners who either intend to stow their dinghies inflated on deck, on davits, or deflated and lashed on a weather deck.
Their extended range at higher speeds, excellent handling and compact stowed dimensions make them an absolute pleasure to own and operate.
Inflatables have pretty dinky interior spaces due to their chunky tubes and forward-mounted transoms. A 9'3" boat may only have 7 feet of interior length, and some of that is in the V-section of the bow. By adding a foot to the length, you gain the same amount in the interior, for a 14% increase in floor space.
