That old Wayler (the board not the sailor!) hits the salt water one last time
This is a diary of progress made (maybe none!) in building a racing sailboard
Sailboarding on a light day at Elwood
That old Wayler (the board not the sailor!) hits the salt water one last time
About Me
- Martin
- Melbourne, Victoria, Australia
- First got involved in sailboarding when all you could buy was a WindSurfer. I had to wait a week before they'd upgrade my teak boom to a new-fangled aluminum one!

Some ISAF requirements and limitations
The minimum weight of the board, complete with footstraps, centreboard and fin, without mastbase shall be 14 kg.
- assuming 14g/l for EPS and a board volume of 300l = 4.2 kg which leaves ~10 kg for the glass, fins and other bits.
A fin shall not project more than 700 mm below the hull in a normal direction
A centreboard shall not project more than 850 mm below the hull when measured normal to the fairline of the hull underside
Maximum beam is 1005 mm
Length (2700mm-3800 mm)
That's it- easy really....
