Ribcraft Owners - Hull thickness

Does anyone here know how thick the hull is at the bottom of the bilge well on a Ribcraft 585?

I'm swapping bildge pumps shortly and need to screw the base down. The current pump is mounted on the sloping section off to one side, but i'd like to mount the new one in the center so it pumps out more water.

Thanks

If I were you I'd sikaflex a small piece of flo-coated marine ply where you want to mount the pump and then screw into that.

Daniel if you can find a copy of the Diver Magazine article from the early days of Ribcraft they measured one, I think at 38mm. This was a problem at the time because the extra glass meant taking one less diver compared to the equivalent Vipers and BWMs. The early ones really were heavily laid up. You could give Ribcraft a ring. Why not just glue it in as Tim says, I didn't have the option on the Tohatsu hull, we already know its on the thin side after Tohatsu screwed straight though it when they put the first pump in.

Cheers Pete - I took your word for it and put a couple of 20mm screws in - they didn't come out the other side so all's good .

Never drilled into pure GRP that thick before - was pretty hard.

I have a Ribcraft 585 and mine is screwed down directly into the hull with no problems.
