I included the image of my first boat as this in a way led upto the Sea Rider. For details click on the thumbnail images ==>
This is the hull of a marine plywood sail boat I built 2 years back and gave away for the token sum of NZ$50 --I had no intention to sell but as the family planned to move overseas, this was the only option.
Constructed of marine plywood and epoxy. The hull bottom was glassed with 6 oz cloth.At about 80 Kgs, bare hull, she was not really cartoppable, by one person.She was built in my car garage but considering the fact that the working space was limited to about 14 ft x 7 ft , and the boat is a little over 12 ft length x 4 ft beam it was an interesting experience. I had to set up some weird pulley arrangements to turn the boat over whilst glassing the hull bottom.Shows what can be achieved if you set your mind to it.
I used 19 mm ( 3/4") T6036 grade aluminium tubes entirely. Even the inserts were fabricated from the same tube. See the Making Inserts tab above.
The separators are 10 mm plywood covered by 3 oz glass cloth and West epoxy, left over from an earlier boat project. I opted to make the snap on connnectors from small pieces of cheap kitchen chopping board.
