removable seat??
Hi everyone,
In order to gain access to under my dash, i'd like to make my passanger seat removable... but there's a catch. I don't want to add any more height than i really have to (deffo no more than an inch) and i can only access the outer side of the seat and the front. On the bright side the bottom cushion is removable. It doesn't need to be able to slide back and forth at all. If all else fails i guess i'll just have to unbolt it all the time!
The reason is so i can store my dinghy and outboard in the centre of the boat rather than the back for weight distribution.
Cheers, James

I did think of that one, had a look on the minisport website, but couldn't see anything that said it will slide out. Also not sure if i'd be able to slide the seat far enough forward to get it off.

I believe fletchers used a similar idea, but i doubt i can get them, and also doubt they were too 'slimline'.
The advantage i have is that i don't need to slide at all, so was hoping to simplify the idea a bit.

what about 2 hooks at the front and 2 pins at the back?

Assuming you are bolting through the floor, how about something like this with the bolts glassed in under?

That was the kind of thing i had in mind, what kind of pins though? I'd need them to be quick release somehow?

Thanks for all the suggestions so far though guys, this is going well! I like burty's idea the best so far but would need some sort of 'quick release' pin.

Removable seat
Hi James, the boat is looking great well done.
What about fabricating a seat base that hinges backwards with a fixing pin/catch at the front to stop you losing your passenger?
As long as there is enough space with the seat tipped backwards to access the space you need, then this could be a fairly simple solution that removes the need to unbolt the whole assembly?

protex.com have a lot of useful ways of fastening things - maybe something that would help?

Not if you have a keyhole plate on the seat base in place of a penny washer. The benefit being the positive locking action.
Turnbuckle arrangement coming through the seat base but you would notice the rattling.
Slot the seat base to go over a simple slide bolt. You would need a wedged plate and sprung bolts to avoid the rattling.
Boarding ladder mounts?

Or are we over complicating this James. It's just the wife's seat that you want removable?
Sorted

BigBird - that's a great idea but there's a 5" high ledge right behind the seat, and even if i got around this, i really need to be able to take the seat out completely.
Cookee - Great site! Can't find anything better than the idea below though.
Motorvator - Now i like you're last suggestion I can see where you're going with the boarding ladder idea but i think it's be tricky getting all 4 to line up properly to put the seat back in.
The Edge - Now that is a good idea!!! I think this is the route i'm going to go down. I can still have them right on the floor and it'll be nice and quick to take the seat in and out. Might be a little movement but i'll just keep em nice and tight. Damn good suggestion

Any problems with movement you could tension with something like clutch springs from a motorbike.

That is the only issue i'm thinking of now... I remember how hard my old bonnet ones were to get in even under a little pressure.
On second thoughts i think i might go with cookee's suggestion. As the seat rests against the ledge at the back, i can use that to my advantage. That way i can have his suggested catches pulling the seat down and back so eliminate movement

Have a look at the Catchbolts - just the job for that!
