hi the centre of the frount beam is 80" or 203cm from the bow, asuming a normal rake? what is normal in degrees from perpendicular?is this the correct length from the frount to put the mast on a normal (production) formula 16?

it is 15'10' is the f16 dead on 16 foot i could extind it a bit but don't realy want to as i am quite happy fitting it up but not skilled enough to maka a hull myself, so this is a ideal project
