Cabin top beams and Deck beams
I am building a 29' stitch and glue cruising sailboat and I plan on having traditional looking deck beams and cabin top beams laminated from mahogany and covered with 3 layers of 1/4" ply laminated together.
The cabin is approx. 5' wide by 10' long and I'm not sure what dimensions I should make the deck beams for proper strength.
1 1/2"wide by 1 1/4"thick perhaps?
Where can I look for guide lines?
