[Paddlewise] question on hull speed

I need a solution to a discussion we have here in Mexico.



There will be a Fathers Race on June 22. Everybody is invited, in Veracruz,
18 kms.



Basis allow for all boats to compete under equal circumstances but there are
some SOTs in plastic very wide and slow and some long narrow boats.

The rule and tradition calls for Tour boats. No K1 or race boats or surfskis
are allowed. But among those there are some less than 15 and some above 19
.



I was going to try to use the hull speed as criteria, but since it only
takes the length and not the width (at waterline level), a wide long boat
will be slower than a narrow rounded bottom  boat.



Is there some rule of thumb to take length and width and try a simple
equation that will give some kind of handicap? I don`t think there would be
time to make hull measurements before the race to run the drag programs.



Last year Jon Brindle suggested me to separate the categories according to
HYPERLINK
"http://www.soundrowers.org/yakclass.htm"http://www.soundrowers.org/yakclass
.htm and I am submitting this possibility, but that would spread to
categories by age and by boat, and that means few competitors in each and
many medals.



I was thinking something like that but penalizing with something like 5% of
time for longer boats (9.25 to 10.99 l/w ratio) and another 5% for extra
fast boats (above 10.99). Runners can work their numbers and decide which
boat to use if the 5% is too little or too much.



Any help will be appreciated here.



Best Regards,



Rafael.
