Boat Winterization 101 Tutorial

Winterizing is important not only in ensuring the safety of a vessel but also in safeguarding the maritime environment. The Coast Guard often responds to cases of vessels sinking due to heavy snowfall or oil in the water at a marina due to poor winterization. The Coast Guard advises:

One last trip
Enjoy one last trip on your boat – and don’t forget your life jacket – taking note of all the things you’ve been putting off during boating season. Winter is the perfect time to complete your “to-do” list of repairs, replacements or modifications on your boat.

Unload
Remove all the gear that has accumulated over boating season and take it home or place it in storage. Don’t forget to take home your fire extinguishers and have them inspected over the winter too! Be sure you drain your fresh water tanks, fittings or lines or you can fill them with non-toxic antifreeze. Pump out any holding tanks and don’t forget about icemakers, air conditioning systems, fish wells and bilge pumps.

Clean
With all the non-essentials removed from your boat, you’ll have room to clean. Be mindful of the chemicals you are using and recycle or properly dispose waste from cleaning. For any questions on your engine, cooling or fuel systems, consult with the manufacturer’s recommendations.

Haul out and wrap
After you haul your boat out of the water, check the boat’s shaft, strut, cutlass bearing and propellers. Clean and disconnect the batteries. Finally, put on any covers or have the boat shrink wrapped.

As with all boating tips, check your owner’s manuals for any special recommendations or concerns. If you have any tips for our readers on what works for you and your boat, leave them in the comments below!
