I have never measured anything, I got the 5.03m figure from some old F16 pages <http://www.geocities.com/f16hpclass/F16HP_grandfathered_designs.html>, and the SCHRS rating for a Stealth and Stealth 'R' do measure the boat at 5.05.

I assumed those specs where correct, if they are not, good.

BTW Wayne, I left before the end of the first race this morning cause I had to go home early, but you all raced the wrong course. You started with a sausage followed by a triangle and the SI call for triangle first...
