My 13 year old made this in 2 days (allowing 1/2 day for paint to dry).
It was both his and my first attempt at building a land yacht and Jesses first attempt at welding (2.5mm electrode).
It worked so well Jesses younger brother, Ryan and I build one each and the three of us are out doing the local Blokarts on light days.
Our favorite sail for two wheelers and 180deg. slideouts is the 6m.
At the local dump recycle centre we came accross 2.9-3.9-5-
6-7-8.5meach.
The 6m. sails are used in the 3 google videos:
Jesses landyachtThere is plenty of length to fit a lay down seat.
The chassis floats on it`s tyres and it may be possible to include a canoe type pod makeing an amphibious yacht?
