SIB floor insert project...

I have a SeaBright 380 SIB {12ft} with an aluminum floor but I'd like to reduce the weight and add a degree of comfort by replacing the floor with a V shaped insert made from a foam core sealed with fibre glass and gel coat.

Has anyone gone down this path ?

The standard aluminum floor gives the rigidity, but it's hard on the knees when you want to stay low in the boat, so an insert as described above, with a top cover of low density closed cell foam as a cushion should be an improvement in comfort, less weight in the boat without any loss of rigidity, and with a greater degree of comfort on the deck.

Other than the above, here's a link to the SeaBright web site, not sure how their prices compare to prices in the UK...

You're talking about your weight, on about 2 x what, 8 square inches (knee contact area), at whatever rate it's slowed by the flooring. I doubt low density foam is going to make any difference at all. You should probably be looking more along the lines of a solid rubber material.

I'm not sure why you don't just get some high density foam padding to place on top of the aluminum floorboard where you would be kneeling or sitting.

i have a foam mattrass that came with my old inshore lifeboat ,its 2inch thick closed cell foam bit like neoprean wet suit material with a hypalon face on one side , bit on the heavy side but great if out in lumpy seas,also makes the boat feel more solid ,no rattles or creaks ,it can be used as a floatation raft if needed too ,the cut out down one side is for the sausage flexi fuel bladder to fit in , regards mart.

I would say go to Home Depot. For 50$ you can get Professional Gel Knee Pads.
And less weight in the boat is not always a good thing.
