There are many days that spot may be just fine. That spot is wide open from at least the WNW to ENE. Tortola at times will offer some distant protection. The issue is you go to bed with your back against a wall with no protection from changing weather from the North.

When you drop anchor on the North side of Salt you are unprotected for nearly 180 degrees. In that position you should have a plan and crew capable moving the boat immediately to safety if and when the weather or sea changes. "Tucked in" would leave very little room/time for error. At least when you anchor in the open the boat and rode should be positioned for a 360 swing to give a sleeping crew the chance to escape a shift to the North.
