what is under the deck of a valiant rib

I am considering installing removal seats into my valiant dr 490. does anyone know how they are constructed under the deck?

i.e. are there stringers and cross members or just foam.

I was thinking of a stainless steel plate with four nut units welded to the under side of the plate. the deck would be drilled to allow the bolt units to sink under the deck. the plate to be screwed and sika flexed to the deck

There isn't much under the deck. I re-fitted one last year, adding under-deck cables and didn't have much trouble running the cables from the back to the front through newly drilled holes. There are a couple of under deck "constructions" but I can't remember in which direction these ran.

It depends on the age of the RIB. The earlier models had stringers, and the later models ( in the past 5 -6 years were foam filled.) To identify this you could pass on the hull number or if it is a later model it will have a ' Unsinkable hull ' sticker somewhere on it.

You could use blind stainless big head fasteners attached to the deck, which would fit in and be flush fitting. A lot less hassle than cutting the deck up. I made an alloy plate with studs for the console to sit on, plate was secure with self tapping screws and sikaflex.
