[Rhodes22-list] Bilge ventilation

Sat Sep 12 22:44:29 EDT 2015

Graham:
I used 2x pressure treated pine lumber for stringers.  I used polyurethane construction adhesive to glue them to the old fiberglass tabs.  It worked very well.  Then i used pressure treated 3/4" exterior ply for the floor.  It is very stable and i hope will last a very long time.  I have also found a nice polyethylene  carpet made from recycled water bottles to cover the floorboards.  It should be long lasting as well and shouldnt hold moisture, dirt or odor.
