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
