Re: [PSUBS-MAILIST] Hull materials - fiberglass???



Hi All,

You might consider an ambient design using traditional FRP boatbuilding
techniques, but for a tradition sub design you will need to build the hull by
winding glass filaments onto a spindle. There are design specs for building
pressure hulls using this design, but for the amateur, the big draw back will be
price. Steel is a lot cheaper.
