Attaching a bench seat.

[Hannibal]

Hi all - another new owner question:

I purchased a 60" flybridge seat from Wise. The intent is to have a secure seat that will hold my two year old (with wife) behind the helm area and also provide some blocking to the open motor area.

The seat came and is nice but has nothing in terms of mounting hardware or instructions.

I am trying to mount it in a way that allows the seat to be easily removeable. When fishing, I'd like to be able to take it out and off the boat easily. When cruising with the family, I want something there for additional seating.

I was thinking about using L brackets and wingnutting them under the floor (with oversized washers) that I can access through the back hatch easily.

My only concern is the amount of stress 4-8 bolts on the floor could produce when in motion.

Is the floor material thick enough to handle this? Should I scab a peice of 3/4" plywood underneath to spread out the load?

Is there a better way to accomplish what I am doing?

It's a 2110 - walk around with cuddy if that matters.

they make those cooler tie down brackets that would hold it. turn buckle tie down and when you want to take it out you can just unscrew the ring that screws in. I have a 170 quart cooler held down this way thats also a seat and it holds very well.

You have any pics of what you are referring to? Or maybe a link. I don't think I've ever seen them in person so I am not familiar with them.

So with these deck plates - is it as simple as just screwing into a stringer and that attaching whatever choice of bracketing I choose? And if drilled into a stringer, I would think it would be solid enough not to have to worry about stress on the deck. This seem right?

you dont even have to hit a stringer just put them in the deck. The ones I used are 3/4" long. Youre not holding the seat up or anything just keeping it from sliding around which it should do about 90% of the time on its own. Its not like a pedestal seat thats up in the air having alot of forces put on it.

IMO - it will create a lot of stress on the deck say when you take off when someone is sitting in it. It will want to rock back and that could easily put a lot of pressure on any mount. I don't know how thick the decking is on my boat (will look) so I was thinking about a sure fire way to get this done.

I am thinking either drilling these deck plates into the stringer or placing a peice of 3/4" plywood under the deck, between the stringers, and anchoring into them. That way the stress is spread out over a larger area.

I emailed the company and asked for their opinion. They should know what works best with their product.

Thanks for the link/info - I knew something like this was out there but didn't know where to find it.

Might want to consider the folding deck chairs. I think they even make benches.
