looking at a Catalina 30, shoal draft of 3'10. any issues I should be aware of. usage will be day sailing "of course" and Bahamas, Keys, etc. I have heard about the dog leg out of Johns Pass...shoal draft sounds like a good idea anyway for the area. Vessel has a three bladed prop..ehhhh..works slower then dual blade prop. I can change that out upon pulling the vessel. that is if i buy her!
