It will carry at least 7 and probably 8 feet. The shallowest part is mostly right by Saba. I find the depth sounders on charter boats to often be calibrated incorrectly. I try and check the first time I am in reasonably shallow water. The dock guys at the charter companies often know the exact depth at the docks to check it also. Many seem to prefer to read depth under the keel and reset it from reading actual depth.
