i have been toying with the idea myself. the only other thing i can figure is to add a layer of wide mesh chicken wire or something inbetween the foam and fiberglassto make it a little more resilient...
If you read thru all of his construction materials,you would have seen that he used HEAVY glass mats and epoxy, so I dont think strength will be a problem
As you may or may not know the 4 rivers boat is only 2 layers of cloth and epoxy WITHOUT any foam other than the floatation in each end and doesnt give it any structura strength at all where as this has the foam as a major component of its strength
I just dont see a problem with strength other than if you are planning on hangin a MM on the transom I think there is 1 or 2 things that I will do to mine to beef it up.
Also he just used the basic kara design and modified it to his needs.
I know 2 of the people that was involved with this and there was almost 2 years of research and experimenting for this boat
Thats lot of work to give up over the net.
Wow, I feel kinda stupid for not thinking of that ...... It should work great. basic concept of modern surf boards, and you know they take a beating!... Man! How could I have missed that! I kept thinking I was going to save up and buy plywood and build a pirogue type boat.... screw that, I'm building one of these! In fact I may build one that is more like a sit on top kayak for retrieving ducks when there is no dog or he does not get them... Then build a kara style boat... Should not be any more expensive than burlapping 3 dozen foamers I think...
