Tolman skiff performance
 

I've always claimed I got 5 mpg in my homebuilt 20' Standard Tolman skiff but to day I measured it over a wide range of speeds using the GPS as my knotmeter and the fuel flow meter. With 4 adults aboard on a plane she gets over 5 mpg, roughly 5.2 mpg. Maximum speed with 4 adults (90 hp 2 cycle Yamaha engine)was 39 mph.
Then one my son's friends wanted to try wakeboarding from it. I had never even considered such but we rigged a tow bridle and it worked very well.

good deal. That's some pretty good economy for a 90 hp. weed wacker.

BTW, Thanks for the refreshing boating post!

Any idea how much your 20 footer weighs?

Without the motor, about 1000 lbs. Much less than an equivalent fiberglass boat which is why a 90 hp works.

Do you have a cuddy cabin or is it the "open skiff" design?
