Somewhere about 1977 the Coast Guard mandated floatation in boats up to a certain length, can't remember the length.
It is there, just likely in key locations. I don't know if sealed air pockets were allowed to count as floatation.

look up under the gunnels, there's spray foam in there. The boat is supposed to float level full of water, too much flotation in the bottom would make it flip over when full of water. I believe flotation was required up to 20 ft, so your V may not have any. We used to have a 20 Sea Ox, not a bit of foam in it, just a bunch of soggy wood

I have seen three V20's in various stages of project on the floors, all three had foam around the fuel tank, two of them had some foam in the area near the junction of the hull bottom and the hull sides around mid ship and a little forward and a little around the back corners. Nothing I would call being foamed in.
One had just the foam around the tank.

Excellent feedback, I DID find foam around the fuel tank when I replace it during my restoration. However its the only area with foam period.
Here is a picture of her with 30 gallons of fuel, two batteries 100 lbs, 58 lb kicker, two full coolers with coolant and ice. She floats really high in my honest opinion..

My 95 V21 had foam in the cavity between stringers and gunwales from bow to stern....that cavity wasn't FULL of foam, but had several inches of it sprayed/stuck to the bottom...wasn't OVERDONE that's for sure...w/rod-boxes out, you could see foam below where they sat...
And I must say, NY Mack...you sure got a PURDY V20!!...nice work!!...how 'bout some inside shots...what did you do around the front of the splashwell?...

Floating high is right. You sure she isn't sitting on the bottom. LOL That V is looking better than ever.
 1983 center console had foam a plenty like Reel's. Fuel tank was foamed plus the entire area outside of the center stringers front to rear. I shoveled it all out. It was dry, so I replaced it after glassing in a few replacement pieces. Foam had to stiffen up the hull a little, I could stand on it.
