Manos, yeah I know that they need to be waterproof
As for the training, I've done the BSAC Boat Handling course (covers Powerboat level 2) and am working up to doing the Diver Cox exam (certifies you at Powerboat level 2 plus a few dive boat related things), so training isn't a problem.
I'll definately look into an anchor, as I'll be hoping to use the SIB as a platform for some freediving and snorkelling, possibly even a few dives with scuba kit when on holiday.
As for HH VHF, what sort of price am I going to be looking at for a suitable unit? Also does anyone have any recommendations for make/model? VHF I'll definately need in case of emergency, and also for communicating with others whilst I'm out, maybe the dive club's RIB if I go out around the same area with them.
As I've said previously, already got life jacket sorted, and the drysuit adds to the bouyancy anyway.
