You have it right. As a former Moorings owner, my understanding is that it is essentially the same, with older boats. Boats are typically at least 5 years old - I am not sure what their max age is, but I'd guess 7-8 years maybe.

I know in the past the office was different, but on the same dock so I don't see any reason you can't use the moorings facilities. I'm not sure if they combined it when they combined sunsail/moorings to one check in process.

I'll add, that having used new moorings boats and 5 year old moorings boats, the age isn't necessarily a huge factor in what works or doesn't - they keep everything working. We've had some older boats that haven't required a single chase boat and some newer boats that have required multiple.
