Regarding Exumas chartering, I don't think there are any other options than Dream and Moorings. I've been down there half a dozen times going back to before the pandemic, and at least from New Providence Island (Nassau), that's it. Both companies operate out of Palm Cay Marina on the SE side of the island, closest to the Exumas chain. That base is crammed and the crossing to the chain is like 35 miles, so it's a niche market compared to the
BVI. There's isn't much support out there and lots of skinny
water and
coral heads at places so they have to make their
money on catamarans, which cuts the potential customer base further.
