The catamaran costed me around dollars sail not included and this is comparable to a store bought catamaran which would cost dollars. In this instructable i have included a few schematics located on the last page , a materials list, and various pictures and descriptions for all steps.
If you plan to build this project i suggest you check out the video and if you like this project be sure to check out my channel or my website for more projects like this. The catamaran will be composed of 2 pontoons.
These pontoons will have a frame filled with the white, less durable Styrofoam in the center; then we will later add the pink Styrofoam to the outside. To start off i lay out two 2x2 pieces of wood with the white Styrofoam pieces in the center. This will be the inside of the pontoon. Next i add a front triangle onto the pontoon.
As you can see in the third picture i added 2 struts near either end of the pontoon. Once that is finished i fill the pontoon with white Styrofoam and cut it to fit in the gaps.
To cut them all at once i clam them together and use a reciprocating saw to cut the height from 2 feet to 17 inches the height of the pontoon.
After that i use 1 - 1. I spread the epoxy on the wooden frame and then lay the Styrofoam down onto the wooden frame and add weight to it so the Styrofoam stays tight to the frame as the epoxy hardens. After that i use the saw to taper the bottom edge. I also add Styrofoam to the front triangle and taper that as well. Once complete you should go ahead and do that for both pontoons.
Note: The strut layout in the second pic is different then the layout of the of the struts in the previous page. The layout in the previous page showed the correct positioning of the struts.
Now you can see both pontoons side by side. To complete them i add a wooden triangle positioned at the top, and lined up with each strut, this will be used for mounting the frame. To add some more buoyancy i also cut a full 2' x 8' piece of Styrofoam in half lengthwise giving us two 1' x 8' pieces. I use epoxy to mount those onto the inside of the pontoons. Now both pontoons combined give a buoyancy of lbs when fully submerged. This seems like a lot but when you consider you wouldn't want more then 60 percent of the pontoon submerged then you would be uncomfortably close to the water and you might also have you weight towards one side of the pontoon then it seems this lbs is just enough for one person to float comfortably.
If you wish to be able to make this a 2 person boat you can add more Styrofoam sheets to the outside. Each 1"x 2' x 8' sheet once cut to a height of 17" provides 62 lbs of buoyancy when fully submerged.
These calculations are fairly simple to do on your own. First calculate the volume of the object length in meters x width in meters x height in meters , this will give you volume in meters cubed. To make the frame i cut my 2x4 s to 4. I chose that width because it was just small enough that i would be able to fit the frame when separated from pontoons in the back of my van.
Next i add the 2x3 piece down the middle of the boat. This is both for structure and to mount other parts off of. Now i cut out the keel out of a piece of plywood. Using the plywood, i also glue a slot so that the keel can be slid in and will be able to slide up and down within the slot.
The keel is an essential part of the sailboat and helps to turn the force provided by the wind into thrust in the forward direction. This is also the pivot point when you turn your boat. The rudder will need to rotate so i decide to mount it off of a hinge. I add a hinge to the back of the boat and then cut the rudder out of the piece of plywood.
The rudder should be fastened in place with 2 bolts and the bolts should have a washer in between the nut and the wood of the rudder. The bottom bolt will have to be taken while the boat is out of the water so that the rudder can pivot upwards when it is on dry land. To finish off i add a handle made of plywood. The handle is to only have one bolt through it so that it can pivot up and down.
To finish up i cut a piece of plywood to size and fit it on top of the catamaran to use as a seat. After that we need to make somewhere to mount the mast of the sail. To do this i obtain a small piece of pvc pipe and heat the bottom of it so i can squeeze it down and make it thin.
Once that is done i simply mount a few screws in it to attach it to the frame of the boat. Now i use a mast and Foam Pontoon Boat Plans Zip Code sail that i had laying around and slide it into the pvc pipe. I secure the mast with metal cables that attach to various points on the boat.
Once the mast is in place i rig up the main sail and the jib and it is now ready to sail. Now that the boat is complete you can go ahead and take it out on the water and test it out. Be sure to wear a lifejacket and bring a paddle just in case you have a hard time getting it in using the wind.
To see the test you can also check out the video. Here are a few schematics of the boat, they are not to scale. Beside the schematic picture i also attached a real picture of the boat. In order we have a top view of the boat, a front view, a side view, and a picture of the rudder and keel. All measurements of the schematics are done in meters. Question 17 days ago on Step 2. Please, how do i waterproof the styrofoam section in boats?
Can you be a little bit specific on the details? Question 9 months ago on Step Can I build a liveaboard with this pink stuff? So, for the displacement argument and calculation, we will leave it in as if the WHITE panel is 17 inches, it will not really make a difference since the wood would also float no? Granted, the 2 inner PINK pieces are sitting higher in the pontoon and flush with the top AWAY from the water, so their buoyancy could be diminished by the fact that they may not even BE inside the water.
Very close to your stated lbs. Then again, I am not discounting the diagonal cut in the front, so that may as well be the one factor that would match it to your number. The platform would cover most of the top portion of the cat, giving more Real Estate to put stuff and people. How much is the buoyancy? How about 1, lbs?
So why would you want this? True, it may be slow as a snail but it should not feel cumbersome as if it had a lot less Pontoon Boat Duck Blind Plans Jump buoyancy.
