It's been several years since I have been on a Blackbeard's trip. One boat only had a few people & the other was full. On the full boat, it is crowded, make no mistake. Some meals must be eaten up on deck or in rotations. Pack clothes & such sparingly,... you sleep with what you bring,.. there is a small shelf at the foot of the bunk,.. but that is it. Your only privacy is a curtain across your bunk & the door to the shower or head (toilet). The beds range from teeny tiny in the front of the boat, to queens for couples. For a single, the bunks in the main salon where the galley is, are the roomiest for single travelers, but it is noisy & not much privacy. The forward bunks are the most private, but they are smaller than a twin. It's a give/ take. You dive 4- 5 times a day. In between they may set the sail, allow free diving hunting (if in season & outside the marine park), sometimes they will allow fishing outside the park.... Be aware that shade can be a premium on the deck,.. but you can always retire to your bunk (where it is air conditioned). The dives are within recreational limits. Typically there are no dive leaders in the water (unless things have changed),... but occasionally they will get in. Hope that helps a little.
