if you sheath the whole rack in marine epoxy and layers of fiberglass it will be many times stronger, and still retain the classic looks.study how sailboat fittings are reinforced with fiberglass at every joint and seam, and add multiple layers of epoxy encased fiberglass at the multiple joints in the rack.bore out the bolt holes in the mounting blocks and fill them with marine epoxy, then drill the epoxy to match the bolt diameter.you will end up with a composite rack with classic wood looks, that is stronger than any metal rack ever could be, if done correctly.Gougeon brothers is the company behind the west system epoxy brand, they offer a free manual that will show you what products to use, and procedures to follow, to make these racks not only great looking, but safe.

If you are in the US titebond II is easy to buy from Amazon or the home depot website. Outside of the US you have more of a challenge. I posted the link to the manufacturers page so you can get a rough idea of what the glue is chemically. More than one international builder has found a suitable substitute by asking around on local boat building pages, or even carpentry pages dealing with outside projects. The paper coating idea sounds like a lot of work. You might look into the shellac coated paper boat building ideas from around 1900.

If the kayak is symmetrical bow to stern, the paddlers seat needs to be just behind the center of the hull for balance. If you make the widest point immersed in the water end up further back, you can move the seat back as well. Your center of mass when sitting, is just forward of your belly by an inch or two, because of the weight of your legs

I think the original design would safely carry 300 lbs with no issues. 400 or more in very calm water, the new design will carry more , probably 4-500 lbs with no issues. If you want to carry more weight you can easily make the hull longer, I'm finishing up a 16 foot tandem sawfish kayak right now, the extra length will carry much more weight. For more stability under load make the hull wider. My plan gives you a boat 28" wide minus a little on the water line. Adding a few inches increases the weight capacity and stability, at the cost of a little speed.You can go up to 36" wide before you can't paddle a kayak.The battleyak is 36 inches wide, and Josh Bryie is a big tall guy, he easily stands and casts from it, and he takes his kids with him, along with a battery, trollin...

TitebondII is very base on the acid scale, if you get any on steel it starts to rust overnight.I use the cheap scissors from harbor freight and change my razor blades often because they are rusted after touching TBII. I don't think you'll have that problem with the expanding foam, people use that for car body repairs often.

You can make any shape out of foam, it may need some wood reinforcement to keep its shape. Im not sure why you'd be afraid your foam Canoe would be light, i prefer my boats to be as light as possible :^) As far as being tippy, that just takes a little adjustment to the design. Heavy materials are best for a hull with a V bottom that settles into the water.Foam barely draws any depth in the water, so a flat bottom with rounded edges will give a stable footing. Just make the bottom as wide as you want the hull, and it will be stable. Sawfish is 28" wide, and I can stand in it easily on the water. The guys who want a design for standing to cast widen that out to 36 inches

24" is a bit narrow, i tried it on one hull and don't recommend it. You would have an easier time by glueing onto the edge of the section you have now.I use a very coarse demolition blade in my skillsaw, they tend to be longer and thicker and resist bending better.

Josh added the wood to the battleyak because it has a motor on the back, i don't think any wood is needed for the floor at all.Remember the fabric skin is the real strength of the hull. I stand in my kayak all the time, it doesn't even dent the foam under my feet. I use thick canvas for the cockpit floor and that is all the reinforcement it needs, unless you are wearing spike heels

there really isn't much reason you couldn't use expanding foam. I actually used it as the glue for my foam mouseboat (google "seafoam kayak") I think it might cost you a bit more, and might not be as strong as gorilla glue unless you follow the instructions in the seafoam instructable to fold the foam before gluing with it..i believe there is a guy in the Ukrane building one with expanding foam right now

Actually I use the Titebond 2 and I really only use it to attach the fabric to the foam. I then fill the fabric with exterior house paint.I did just read on duckworks magazine about a SOF kayak that used titebond II to waterproof the fabric. You might want to look into the wooden canoe forum, and read up on using shellac to waterproof and protect the canvas. That was wat the old maine builders and guides considered the best protection for their canvas skinned boats. They claimed that the canvas just slid off of rocks and showed no damage.

The denser foam will resist dents and dings better, it will be harder to shape with the sureform, so plan on using a hand power plane for that. Laminating foam gives you a stiffer hull anyway, so if you can get thicker foam, do it as it is cheaper. Fabric between the layers will require much more glue.the only place I see an advantage to laminating is to make a SUP.Laminating and skinning foam makes it stronger, im not sure if bending really does much

The biggest problem with EPS (beaded foam) is that the little voids between the beads will suck up and then hold water. The sawfish that was just launched in the Azores is made of EPS, as he had no way to get XPS there. He used a waterseal product to seal the foam, then wrapped it with fabric. I don't know what the long term condition of the boat will be, but if water gets in, it will get heavier and ride lower over time.Obviously this type of foam is usable though, as Snark sailboats as well as many fishing gear floats, and even dock floats are made of it. The trick is getting it well sealed.Your paper mache idea could work if the paper layer is waterproof. I don't know what kinds of paste there are that would remain waterproof, you may know better than I do, or an art supply place or ...
see more »a few other people in the comments have run into the same issue, and atleast one has actually launched his boat. (he painted the foam, then sealed it with polyester resin)The only other guy I know who has had a lot of success building with EPS, does a two layer skin of marine epoxy and light fiberglass. But as I said below, this is expensive, costing nearly as much as the rest of the boat.

Coating the foam with fabric as shown in my poor man's fiberglass instructable keeps the foam from being worn or damaged, and makes it much stronger. I'm still exploring the different ways to build with foam, your catamaran is great!

Looks great! I'm glad you tried a different way to build the boat.it gives people some options when they don't have the materials I can get. I do think that you will find those extra stabilizer ribs on the bottom will make the boat slower, but that is the beauty of foam, you can change the shape quickly and try new ideas.

I started to build this boat years ago, then lost interest. My daughter wanted her own kayak, so I taught her how to build a stitch and glue boat. She did most of the work and got to launch her new kayak this past spring. One change we made was to replace the plywood bulkheads and fecks with foam to save weight. I've gotten to paddle her boat a few times and am very impressed at how fast it is. Now i want to add a rowing rig to it to really get some speed. Glad to see another builder finish one of these.

Fabrics don't like to bend around sharp corners, round them off and they shouldn't fight you. With TBII, it gets tacky and holds quickly. If you are using paint, it takes a while to get to the sticky stage, i use staples to hold the edges down then.

the fabric on the hull adds quite a bit to the strength, dent and puncture resistance, and waterproofness of the seams. you could try the aqua blocker over fabric on a test section of stryofoam, try 1 foot squre, wrap it completly, and coat it with the blocker. when it is dry, weigh the test sample, write the weight on it in marker so you don't forget. then submerge it in water for a full 24 hrs. at the end of that time shake the water off the surface and weigh it again. if there isn't a signifigant weight gain, you shouldn't have much to worry about, as you probably won't be afloat in your kayak for a full 24 hours, more like a few hours, if you are like the average paddler.to see what will happen if you get a hole in the skin. punch a small hole in the fabric on the test sample, and s...

Small human powered boats come in standard widths, under 36" wide is standard for kayaks, anything wider than that requires a very long paddle. 48" wide is where standard width row boats start. Standard meaning that they don't have out riggers for the oar locks. Unless you are only going to use a motor for propulsion, I believe that you will find it awkward to paddle at 48" wide that is why I recommend stabilizer floats for standing.
And the blue foam is the same stuff, just a different manufacturer.

I can stand up in the original, though I find you must be agile to pull it off as an adult because the boat is so light.Back in July i ran 10 miles on the Saco River in seafoam. At one beach area a group was admiring her, so I spun around to show how easily she can spin in place, which is good on a whitewater river, and then stood up in her as I drifted backwards on the river. They were impressed. I didn't tell them that actually seafoam is not a great boat for whitewater as the center of the v bottom kept grounding out in shallow water that my family in their foam kayaks were skating right through.I found that the trick was to scoot as far into the front of the cockpit as possible, this reduces how deeply the boat sits in the water.

the 1" is just for the decks, you don't need it unless you want to finish the top of the boat like I did mine.You could just leave the bow and stern open, or use 3/4" for decks.

I think you can skin one boat per gallon, possibly more, this isn't a step to try and save on, as the glue bond to the fabric is the real strength of the hull. PLpremium will work for laminating the hull layers, but it is harder to carve away when shaping the hull.Using a power plane would make this much less of an issue. PLp is also harder to get to spread thin, and I don't know how well it will grab into the pores you make with the scoring tool.The bond between the layers is the key to a hull that doesn't flex or sag
As long as it is XPS it will work, the color doesn't matter. I tried some of the Lowe's foam and found it much tougher to shape, requiring me to use the powe plane, which I found I liked better than the sureform anyway. I just can't get 4x8 sheets of XPS at Lowe's locally. Sawfish takes 1.5 sheets of 4x8'2" foam, and 1 4x8' 1", if you follow my Instructable to the letter. Three sheets of 4x8' 2" is enough for two hulls.
View Instructable »Based on the experience my wife had with a boat with just a small skeg in the stern, i recommend a strake that runs most of the length of the bottom. Unless you will be paddling on fast moving water, like shallow rivers, the ability to hold the bow into the wind is a safety issue. The strake doesn't need to be deep, an inch over 10 feet would be plenty. The cutting board strake / skeg is cheaper than anything else I know of.

XPS foam is one solid block or sheet, not a sheet or block made of thousands of tiny beads of foam. Near the water you might look into places that sell foam blocks for floats for docks. The beaded foam, like cheap coolers are made from, are EPS, EPS will soak up water over time, unless coated with a waterproof coating like marine fiberglass and epoxy.The butterfly joint is just a way to clamp the edges together tightly without needing long clamps. As long as the surface isn't smooth the glue should make a strong joint.The joints and layers help the hull resist flexing too much, the fabric skin is really the strength of the boat, you could build it out of cardboard and wrap it the same way with no issues, until the cardboard turned to mush.

Yes, the number of joints won't make a difference in the strength of the hull. The only downside will be extra work, extra cost, and that shaping will be harder as the glue joints are harder to shape without a dip or buldge. Using the power plane to do most of the shaping will keep the seams from causing issues

TBII will work if you are very patient. It is a water based glue, and that water must evaporate for it to cure. This can take weeks as the foam is waterproof, with wood the water is just absorbed by the wood.Gorilla glue is cured by a process that uses water or water vapor as the catalyst. As long as some water vapor is around, it will cure overnight, even at the 40 degrees F my basement is kept at all winter.TBII might never cure in the basement.

Styrofoam absorbs water in between the little beads of foam. You can still build a sawfish kayak with it, but will need to seal the foam with a fiberglass skin. This will roughly double the cost, depending on the prices for marine epoxy where you live.For me it would make the cost just a bit over $200 for the complete boat. Do not use polyester resin, it tends to eat foam

You're welcome, I love hearing about.I believe you are the builder of the fifteenth sawfish! If you have any pictures or a name for your boat, we would all like to see them
I've looked into just about every type of boat building, I like the skin on frame idea, except for the possibility of getting hole and possibly sinking. Is fuselage frame like, skin on frame? I ended up with foam as it is unsinkable, is very light, and won't rot, rust or corrode
You can also locate where you want stuff, then make a larger hole in the foam than the screws, and pack the hole with PLpremium, insert the screws and hold them in place until the glue cures. Heat a screwdriver with a lighter or torch and hold it in the head of the screw until it softens the glue enough to thread out.Of course wood gives you an easier way to mount and move them. I hope you share some pictures of your boat

Great stuff is hard to foam into a solid shape, it tends to leave voids and be weak.It also soaks up water like a sponge. If you got any holes in the fabric skin it would suck up water and get heavy.The xps is the structure of the boat, spray foam is not stiff enough

Definitely, though it might be easier and more useful to add a socket for a 5 gallon bucket for the live well, and leave the rest of the cargo area for gear, pump, battery, etc.Also don't forget that the water in the well is heavy and will affect your trim and balance. If you look on the kayak DIY project and tutorial page, there are many examples of pet food storage bins with the same screw hatches being converted into live wells
