fixing in seats

Hi all,

I'm after some advice about fixing seats into my rib. It's a 4 metre avon searider with a double jockey seat. I want to fix another seat in the back but am not sure how to fix the seat to the floor. Any advice on the type of seat and hoe to fix it in would be greatly appreciated?

It will be used to carry passengers and as a fishing seat. I dont want a bench seat unless it has a back to it for comfort.

Thanks.

Kaz

There's not a lot of room in an SR4 for another jockey, you might be stuck with a bench.
At least the underside of a bench gives you storage room.

Sikaflex 291i and stainless self-tappers for fitting,or you could glass it in if you're feeling confident.

Agreed, I measured 40mm between engine and jockey including leaving a bit of room and wondered whether i could get a single captains seat in that swivels but wasn't sure how to fix it? If i used self tappers would this not cause a potential leak. Forgive my lack of knowledge but I am new to boat owning so learning as I go. :-)

FWIW I bought my used rib from the manufacturer and wanted more seating.
They said "sikaflex and self tappers" is where it's at now.
If it was new from factory, they would be glassed in.
So, if done correctly either is fine as a method of installation.
(I went for the OEM spec and had them glassed)

The under-seat storage is great but we've yet to fill every seat so measure need against expectation with a cold anti-social eye

A swivel captains seat will likely break the deck (and if it doesn't it'll be unstable) -it's quite thin on an sr4.

Sikaflex 291i is a polyurethane flexible marine sealant.Screw the new seat base down onto a bed of sikaflex. It'll squeeze into every available gap as the screws tighten. (masking off where the base will go with WIDE masking tape will help as well, Sikaflex goes a long way)
it's a very very strong way of fitting a console.

Aww

At the risk of showing my ignorance of SeaRiders..although I expect to remedy this very soon........
Would you be better off putting the additional passenger sitting on the tube? Not ideal, but lots if sailing clubs manage quite well.
To me Ribs, below a critically expensive length, are one directional. You face forward in the seat. Everything else is a battle between your ankles/knees and the boat.
Cluttering the deck space with an additional seat may frustrate you when fishing when you want to move about.

Ahh thanks that has helped me to understasnd. So i use the sikaflex to create a false floor which i position the seat on and use the self tappers to fix the seat to the sikaflex which will harden and secure it. That sounds like my best option, thank you.

Thanks for your reply. I will mainly be using the boat to take friends out for some fun, some are a little nervous and would feel safer sat in the boat as apposed to on the tubes. I will also be taking my dad out on a couple of fishing trips.

Just on the Sikaflex.

291i is a multi-purpose sealant and adhesive. If you are really trying to glue them down, 292i is a better bet but the key to successful bonding using either of these products is decent preparation.
