Re: How to check for voids?
Most will be difficult to find. The best way I have found is to flex the sheet slightly and sight and feel for flat spots. If it looks flat tap lightly with a hammer or mallet to see if it is solid inside.
The plugs are fine except for the face of an appearance...
I just decided to get on the water with something I could overnight aboard if need be. Mostly going to be a fishing platform, most sailing will be to and from sites. This bay was at one time the largest fresh water fishery in the world.
Well the boat build is off the table for now. I have gone over to the dark side of the force and purchased an O'Day DaySailer in fiberglass. 16' 9" long sloop rigged,will float in seven inches of water. Should be great for fishing and coastal cruising.
