Be sure to design it well. A flexing stainless frame will crack more easily that you might imagine.

I think as said earlier on this thread, your engine is quite wide, whereas mine is quite narrow. My a-frame is on the inside of the transom, but I can't see how that would make much difference. The engine does nearly 360, but I get more than 180 degrees out of it which is great cos you can make the boat behave just like a tug with a Z-Drive underneath

edit: sorry, I have just seen - my a-frame curves over the tubes the moment it is above the transom which allows the engine to go in place.

If you want any more pics, let me know.

Thanks Alex, that's the sort of A frame shape I have in mind (though a single tube), hopefully will be able to get somebody to make me one which will fit in the original holes to save ending up with a transom that looks like a bit of Swiss cheese!

If you could take a photo of yours where it actually bolts on, that would be great, thanks

Hi

I had the same problem on my searider so beefed up the A frame to take the bracket and added some loops to tie it top and bottom

When I did mine someone on here sent me a picture of some good brackets i'll post it if I can find it

Thanks - that's a neat idea. I don't know if my A frame would be strong enough to do that but I have plenty of alternatives to fiddle with now! I also see the other pic shows what appears to be a horizontally offset bracket which may be another solution.

Thanks to all who have contributed to the thread

Well after some fiddling and measuring, I decided that the the A frame had to go, and there is plenty of room now ... the A frame bolt holes now have some S/S eye bolts to fill them up, two on the outside in case I ever need to tow anything (replacing the stupid wiggly hooks that were on there before) and two on the inside which will give me something strong to tie the mooring line back to, as well as something to put a rope off the aux on to just in case it falls in the oggin

All I need to do now is sort out somewhere to stick some nav lights and the VHF aerial, it has been suggested to me that you can get an all-in-one red/green and all round white light, and that I could stick one of these on a single pole at the back of the seat base. Anybody got this setup, or where do you have your nav lights on a RIB without an A frame? I suppose the side of the console is an option, though they might glare a bit if they are in front of you?

The harbourmaster says that the Prevention of Collision regs require nav lights to be fitted even on a RIB, but he didn't seem too bothered about a "temporary absence".

Also found out why my VHF reception was crap, because the coax going into the plug wasn't sealed properly and had suffered from serious corrosion and water ingress ... so that's another job on the list then.... run some new coax right the way through. Ho hum

Why don't you put a single pole on the other side of the transom? It wont be on the centre line so not strictly correct but it'll only be off centre by 500mm or so and viewing your boat from a distance, that'll be neither here not there. And you can still lean against it when having a pee.
