still think both are good and still like the pole idea , question is how many ribs go out at night and need these a frames when a pole will do , in the Case of Manos and his charter ribs i can see the sense of a light pole with cross trees
for mounting vhf ariel and gps ariel as his boats are probably tucked up in bed when the sun goes down, also if you made the base plate strong enough you would get more hieght for towing wakeboarders and the like , Sports boats open type do not use them, alot i guess is the rugged go anywhere 4x4 appeal of ribs and how they look, both do the job just depends on what you want.

Why "A" frames

In S.Africa we did not refer to "A" frames as "A" frames but as "roll bars". This because most of our launching took place off the beach directly into the surf. This is a releatrively dangerous activety and the "roll - bar" was to protect the motors in the event of fliping the boat duting the launch. For this reason nav. lights where never mounted onto the a-frame.

I deliberately did not spec an A frame on my Scorpion - the only advantage if you don't have a radar is that it keeps the all round white light high and at the stern - most other places and it ruins your night vision. They do however make good climbing frames and good to tie up to.

What were your reasons for not wanting one, Mark?

And, as has been mentioned earlier, it gives you a foot or two more height for your VHF aerial, which has to be a good reason IMHO.

Now I understand Cheers

Tim you know how Greeks do things better than the Greeks. As we see it this year there is no need for A-frames (roll-bars) on our boats. No one uses them at night and not very many people requested to have skis or knee boards either. So the next boats we will get will be with just a ski pole doubling as a flag pole and having on the top one all-round white (anchor light) and two all round reds. The boats are equipped with torches and handheld spot lights any way. None has been used so far.

I was meaning that with my current state of finances and the fact I've already got a stern A frame I couldn't justify the cost of having one built.
It would be a different matter if it was a new build and I seem to remeber these one for sale in the bits and peices section.

No argument Jelly. I agreed with you. The cost for making an SS frame in Greece with some kind of bimini on it is a lot and I certainly will not do it for the hired RIBs.

Yeah, and a couple of serious points as well in favour of A frames. If you've got radar you most certainly want it above your head... not good microwaving your brains (maybe not quite the right smilie but gives the right image!)

And the same applies to VHF. Weaker signal but still not healthy to stand directly in line with transmitting aerial.

I wanted a low profile - especially when on a trailer - I have a long aerial and have had no problems with range or reception.
