If taken out to sea, and a large wave crashes over your boat, it will surely be swamped. With skill and blessing, your Carolina Skiff may survive the inrush of water, but don't count upon it, and take your flat-bottomed boat out there when the waves are boisterous. Sea Skiffs, obviously, are built to resist such waves and may be taken out. As to other forms of sinking, a hole may occur in the hull and thus sink the boat. Keep sharp objects away from the hull, and be careful around shallow depths depending on the depth of your draft and of the waters you are in.
