: I have just started the yost Sea Rider.The table of offsets for the sea rider
: are in feet as the other yost boats are in cm.It says (ftx12)x2.54=cm to
: convert.Lets say at its widest HB at section 4 is .811 ft would be 24.7
: cm.Is that right? It doesn't seem that there will be any leg room or room
: for feet. I am building this for my wife whom is very short but it seems
: it will be small even for her.

Well, 24.7 cm is about 9 3/4", and that's a HB. The boat is 19 1/2" wide, so about 9 3/4" is just about exactly half the beam. So, yes, that's right.

But it seems you are referring to the deck heights? That would be the HAB (height above baseline). I agree that there's not just tons of leg room, but it'll be OK. If you feel like it's needed, it's very easy to just make the deckridge - at the masik - an inch or so higher. I've done it plenty. Don't make things higher at the chines, though!

Good luck!
