Haven't been on this site long but, to me it sounds a little iffy to me. If you don't get an answer to your question by someone with onsite knowledge of your area and hunting / weather conditions in regards to your boat, I would suggest you post it on this site:

duck hunters boat page

The fellas on this site took a green rookie like me and taught me how to build two duck hunting boats and now my own set of cork decoys. But what they really have is a heck of alot of knowledge and free advice. They have members in your area.

Hope it helps, and good luck on your season. Be safe.
