Defining boat size by bottom paint

There are lots of measures of boat size (LOA, LWL, displacement etc.) but as I was painting the bottom of my LeComte Northeast 38 this week, I discovered it took 1.5 gallons to paint one coat.
It strikes me that an interesting demarcation line is between sailboats whose bottoms you can paint with one gallon or less and bigger boats that take more.
I _assume_ you can do a Triton's bottom with less than a gallon?
At about $200 per gallon, such questions become more than idle curiosity :-)
Anyway my rambling for the day.

You can just put one full coat of VC-17 on an Alberg 30 with two quarts; but then that particular paint goes on rather like water. Not sure how much ablative it would take, but more, I'm sure.
One time some people were moaning and groaning good-naturedly about how hard some bottom work was going, and CharlieJ (from this forum) chimed in to say "You think you've got it bad? I had a 36-foot trimaran - that's over 95 feet of hull!"
I'd never thought of it that way before, but... yikes!

I can paint my top foot, leading edge of keel and rudder, then a full coat on everything with a full gallon of Micron Extra.

See, that's why I wear old tennies for the job ;)

We do our NE 38 with 1.25 gal.; I guess yours' is bigger.
Actually, I have a very neat way to do the bottom, Rachel: Sue does it.

I can only imagine what Rachel would say if I had revealed the other things I paint in the process as well, sheeesh. No one gets a break here. :)

I used Petitt ablative paint and a roller, I suspect the kind of paint may make a difference.
Another factor is the I raised the waterline a couple of inches.

3 gallons gives me 2 coats of Micron CSC. I can get 2 coats of Micron Extra on with only 2 gallons but it doesn't last as long as the CSC.

That is an interesting way to size boats but very practical. I can just get 2 coats out of a gallon on my Marlin which is quite convenient.

1 coat on a Shark24 = just under 1 quart of VC17
