FRP cross beams
4 Replies

Has anyone used FRP cross beams instead of fabricating their own. I have a good supplier of 6"x6"x20' pultruded beams. Seems like it save a lot of labor if strength is equal. Any thoughts?

"I would be concerned that fibre orientation may not have enough  reinforcement across or diagonal to the beam axis. At points where there is compression --lashing points -- the laminate could then crack along the beam.      …"

"http://www.libertypultrusions.com/pultrusion-products/fiberglass-beams/ Here is a link to the type of product I am thinking about. There are several manufactures in the us. The 6x6 beams come 20'long and are 3/8" thick. Any thoughts?"

James Ryan davenport replied to patrick lennon's discussion Glassing fillets to bulkheads
"Yes. Bilges and any place that is not easily accessible where water could collect. I think glass ing saves time overall because the wood can be treated in one step instead of painting with epoxy and sanding several times"

"I use one yamaha 20hp 4stroke in one holliday. My original motor is one 9.8hp 4stroke. The yamaha only consumes more gasoline, and the boat goes little faster( my motor 6,5 to 7 knots, yamaha 7 to 7,5 knots).  I think the best for tiki 30 is…"

"Yamaha makes the 25hp with a 20" shaft. You can put a 5" extension on from Bay Manufacturing. They have built these extensions for many years. The gearing can be compensated for with prop pitch. With only a 20" shaft corrosion will…"

Budget Boater replied to James Ryan davenport's discussion 25hp on tiki 30?
"No, 25hp is not "too big." However, if you plan to use this engine on your RIB, you will most likely need to lower the engine well on the T30 since it is designed to have a 9.9 sail drive 25" shaft engine on it, not a 15" shaft…"
