Pete7 is your man for this.

He devised his own solution - do a search on "diy jockey seats" http://rib.net/forum/showthread.php?...y+jockey+seats

[jwalker]

If you're happy to hold it down with ratchet straps I can give you some info. Yes/no.

Hi I have been using these up till know but wanted a semi perminent solution, having said that what is your idea?

Hi Nick
I use theses fixings for making units all the time where the unit is to big or heavy to be assembled in the workshop, but i dont think they will stand up to the stresses and constant tightening and un tightening of the bolts in this situation,
the insert themselves tend to work loose with constant use the threads are vey small.

Pm me your details and ill send you a sample to use as test if you like.
size would be M6 .

Nick ,if the thickness of your floor is less than26mm what might be a better solution is to use insert high performance cavity fixings, take alook on RS webb site www.rswww.com tel 01536 402888.
item no 520-863

I presume you want to leave the deck clear of fixings when the box is removed and you donot have access under the floor at this point.

Nick, think about what they are going to be like after a couple of years in a saltwater environment. Although I used S/S bolts and Aluminuim T pieces they are covered in a marine grease and after a year show no signs of corrosion. Not sure about zinc plated things though.

If I was doing it again I would glass a piece of 18mm ply down to the deck with top hats mounted on the under side. With another layer of glass over the top that should be strong enough to take the weight of a couple of people in a rough sea.

Thanks for the offer if I go for it I would us the larger SKDZ2510 Zinc M10 25mm 12.2-12.5mm which should have a good hold!
I would not be removing them that often so should not get excessive wear.
I have looked at the cavity fixings but I think that Insert Nut will do the job better as cavity fixing would rust!
Yes I do want a flush deck & cannot get under the floor!

Pete
I do like your way of doing it & may end up going this rout. But the Insert Nuts are Zinc alloy die-cast so I think they should not rust!
I do want to end up with a flush deck so the ply idea is not for me

Thanks to you all Nick

The zinc will rot faster than a very fast thing, that's why anodes are made out of it.

[aligator]

Execellent point, scarydes

Alistair

[Nick Hearne]

Des thanks for that I was wondering about that & Surprised no one came up with it till know!
Looks like I will be taking my hat off to Pete then! Or sticking with the rachets!

Apologies for the delay, Nick. This is simply a way of holding anything down to the deck. I used it, long term, for seats and a fuel tank and generally for jerry cans, water bottles, a folded dinghy, fish box full of ropes, and various other items. It works well and I've used it for a good number of years without a problem.

The aluminium track is marine quality and anodised. It's original function is the base of a rubbing strake for a hard boat where a rubber insert slides into the slot. The wee brackets you'll have to make yourself. The track was sourced from Wilks.

I hope this is of some interest.

Now, I could be talking rubbish here, but the zinc fitting in the deck would be electrically isolated. So would this prevent it from corroding?

I fixed my seats wir s/s screws in s/s Insert Nuts. Looks like the
picture on top just not made out of zinc but of V2A Stainless steel.
No problems with rust for the future. I bought them in Germany infos under www.inox-schrauben.de

[Nick Hearne]

Hi Spitfire
thanks for the lead on these, I have had a look & it looks like just what I am looking for I have used a web site translater as my German is no existant! I take it they are stainless steel?
Can I ask you to confirm I am looking at the right thing!
