Our party of ten (six kids ages 8-16) did well with two sup and one double kayak plus noodles for all. Dinghy did fine with ten. Longest ride was on JVD from Roxie's around to soggy. We went with beginner sup knowing there would be more than one kid on the sup at a time.
Fishing on the mooring can be a lot of fun - very active. Fish like chicken or any left over dinner vittles. Cheers.
