Welcome aboard. Plenty of ole' salts here to answer your questions. Just a few points I've learned over the years that might help. 1. Check the charts
for the area you're boating
in. Hazards under the water
don't stick to a uniform distance from shore when hiding. 2. When you're draft
exceeds the available water depth
, you are most assuredly aground! 3. If you sail (boat) you will eventually go aground, be prepared!
Stick to the deep water until your knowledge of the area improves then you can get a little more adventurous. Good luck!
