Gelcoat blisters and rocker?

[jasoncooperpcola]

Trying to get the V20 blocked in the garage. I am seeing lots of pencil eraser sized bumps on the bottom. Some are dime sized. Are these gelcoat blisters? Some places the gelcoat bubble has busted off, and lets light through. That is how I discovered them.
Next, do V20s have a rocker in the bottom? Its either a rocker in the hull or a bowed up garage floor.
