Agree, I'd hate to be doing any sort of rescue job with that gantry over me.

Also, be very careful about insurance, skills level etc if doing safety cover in anything other than a club owned boat - it suddenly becomes a whole different ballgame.

i haven't got the full roofrack (more like an A frame midships) and i love it, it's in a sensible place for people to hold onto, i sit on the self righting bag when i'm ticking over 'whale watching'

Thanks for the replies, all sensible advice. I hadn't considered the potential issues of dinghy rigging getting caught up in the rack. It is a very valid point. I think the answer will be to custom build a lightweight frame with easily removable sections so it can be rigged to carry out whatever role I want it to perform.
I think rather than buying an actual Camel, I will look for a good standard platform to work from and develop what I want from there.
For my frame work, I might consider using Carbon Fibre or such like. I would be looking to keep the weight to a minimum to reduce the centre of gravity as much as possible, as well as the windage.It wont be carrying much weight, just bulky things such as a windsurfer etc A lightweight cover would be good to keep the worst of the elements off.

It is interesting reading the comments regarding CAD. I use CAD from time to time to assist with vehicle designs that I get involved in. I use 2 different types, Cardboard Aided Design to work out the basic object that needs fabricating (in best Blue Peter fashion). I then start bending and welding metal and when I am happy with the finished object, I draw it in Autocad. This way I know it will work and do the job intended, occasionally I have been able to refine my design using Autocad, but the bulk of the work is always done hands on.



I am looking forward to this project, it will have to wait until the winter and when I have finished numerous other projects currently cluttering up my yard.

Just a thought, but what elements are you planning on keeping out of? A "lid" will keep the sun off, but be as much use as a fart in a spacesuit for keeping rain off when you are travelling at any speed.

If you're designing your own to carry windsurfers, would you maybe be better with a couple of short uprights with a horisontal (A bit like a canoe roof rack on a car) with the upright as close to the toobs as geometry will allow, and carry the board along the top of the toobs, supported on the horizontal beams? Will reduce your aero drag a lot too..... Doing that if you design the support right, you could then remove the windsurfer rack, plant your windsurfer mast in the hole and hey presto, instant committee boat for the dingy racing!

the frame's aluminium, mine was a photo boat so it's the smaller version and so far hasn't shown any signs of stress despite thumping my head off it numerous times
Pass, and i don't remember the number, but when i was looking at one, it was definitely plated by Ribtec for more than 130HP!

The roof would be for when the RIB is stationary or pottering when doing rescue /committee boat duties at the sailing club. It would keep the sun off and the worse of a downpour. I wouldn't expect it to cope with anything more than that. I quite fancy doing some cruising type stuff as well. With a full length framework it would be possible to fabricate some curtains that would convert it into a tent.
