Based on the current hull (retractable centreboard) being raced at the moment in Australia, the plan dimensions
are 3.65m long x 0.65m wide. The weight of the board without centreboard, but with skeg is around 21kgs. This
can however vary by a half a kilo either way. Based on my calculations you should assume the hull's volume is at
best 200 litres. It's nowhere near 250 l. In the distant past I've heard a figure of only 180 litres but I think that is
way too modest.
Although it doesn't affect the above numbers the OD's rocker line is where the main differences lie between this
class of board & other one design raceboard classes. There are large variations with the OD which do impact on
its overall performance, but that discussion (if needed) is for another day & time !
