Make sure all your safety gear is in order.
Get a radar reflector.
Leave your handheld vhf on IN the house for a few hours to make sure the battery isn't on its way out.
If you have an EPIRB, test it, or have it tested.
Doublecheck all those lifejackets to make sure they're all clean and intact.
Make sure your GPS is happy and working and giving you good info.
If you're unsure of yourself, take a boating class and go out with more seasoned friends.
9/16/22 are busy enough these days. Don't need more accidents waiting to happen.
Life Raft & Survival Equipment, Portsmouth RI is the place to go if any safety equipment needs to be replaced. (I'm not affiliated but most people I know use and trust them with their lives.)
