Many thanks indeed guys.

Yep I'd discovered the cat is about 1K more expensive but as our Son is now 6 ft 2" and 17 yrs (so possibly may get taller) I definitely think the space inside the main and sleeping cabins will be worth it.

I'll pass on your suggestion about hiring a skipper as that sounds like a great idea.
