Hi Kaz,
You need to watch the rear section of the Searider floor as it thins down in the last 300mm from the transom to one layer of plywood: if you look and or feel up through the rear drain outlet of the hull you will see what I mean. Better use jeffs' idea and use an inflatable seat but in front of the jockey unit - that way you will see they are OK. Best wishes iain

No. Unless I am reading it wrong.
You will apply sikaflex to the floor (or seat base) and then screw the base to the deck which compresses the still wet sika. It is a very good adhesive as well as sealant so glues the seat and seals any gap. It is very important you use a proper marine adhesive for this and not just some bathroom sealer. https://www.pbo.co.uk/news/maib-repo...ck-seats-12819

To give you an idea of the strength of Sikaflex..I was removing a console that was held in place with self tappers and Sikaflex, I removed all the self tappers and placed a strop through the console to lift it out with a tractor. I lifted the WHOLE boat up off the trailer when trying to lift console.


I had to cut it out in the end.

To give you the opposite story - I know someone who glued down all the bearers for a floating floor in the wheelhouse of a boat. When everything dried, you could just peel off the bearers and the Sikaflex. There was apparently insufficient time to prepare the substrate although it turned out that there was sufficient time to do it twice!

+1 although i didnt have a tractor to hand i cut it with a multi tool then used hardwood wedges to crack the seal and thats a joint between a fiberglass jockey seat and a flow coated floor.replaced with shock seats on aluminum bases stuck down the same way with no probs.
