On Top or Below??

Post by greenchicken »

Mounting my stowaway seat and I was curious if it mattered if I bolted it to the top of the deck to the the bottom of the deck.

Here is how I did it. But I can easily change it.

I would think you want it on top so the seat will spin.

I think Top would also keep the Carpet intact around the hole better. I think after some where and use the carpet will start to fray and peel back at the hole. Also would be structurally better as the weight is pushing down and the Plate helps the entire area absorb the weight where as right now with it underneath the deck is supporting the weight only at the bolts which would eventually pull through the wood after extensive use and weathering.

Maybe you could take a flat plate the size of the plate on the seat pedestal mount and drill a hole in the middle for the pedestal. Then you could sandwich the wood with both plates and not have the trip hazard with the mount on top. It wound also protect the carpet from fraying beyond the hole. the top plate would increase the area of support dramatically.

Thanks for the feedback.

I mounted it this way because I thought it would be more attractive and less of a trip hazard. But the 6 bolt and the hole negate that.

I'm gonna put it on top.

Seal up the holes in the wood. If you can, slightly enlarge them and glass the wood holes so water won't rot it out. My last boat had one of those on a piece of wood and it just pulled right off because of the rot.

Take KMixson's idea and take it a step further. If you can remove the carpet or want to redo it at some point, take a router and cut an indention in the wood a little bigger than the plate and a bit deeper than its thickness (to allow room for the thickness of the carpet under the plate). Reinstall the carpet and voilá. Cean looking flush mount with zero trip hazard and enhanced structural integrity compared to the seat bracket alone when mounted either above or below the deck.
