Rather than faffing with a sail boat, which generally have limited space, who’s skippers are normally nervous of getting close in and tender transfers to shore are a hassle, consider a motor vessel with skipper, skippers mate and cook. Get a local one who knows the waters.
The only one I’ve been on is the MV Cuma, takes 10-12 or so punters at about £900-1000 per head for the week as a private charter. If you joined a commercial outfit hiring the same boat and skipper it would cost you x 2.5 as much.
Other options are available. When booking remember the skippers word is final. Just because it’s a private charter and you have spent alot doesn’t mean you get to dictate.
