Three ways of storing your boat:

In-water boat storage 

Winter weather is different all around, from snowing to raining, so depending on your area's winter weather conditions, this option might work or might not work at all. Leaving your vessel in the water during winter is not recommended. There are many risks to think of, for example, sinking, storm damage, and blisters.

Dry outdoor boat storage

This option is the most cost-effective; if you have space for your boat, then go for it. However, this is not the most preferred option as leaving it out and dry without any protection in bad weather conditions can damage your boat. You can avoid damages by maintaining the vessel and keep it well protected. 

Dry indoor boat storage

Storing the boat inside a covered area can be expensive unless you have the covered space in your backyard. Storing indoors is considered the safest option, according to many "boaters."

Winter Battery care

It is all about "TLC" tender love and care when it comes to our boatBatteries are essential components of the vessel. As a boat owner, you must prepare your batteries before winter and maintain them during winter.

Protect your marine battery

Regular maintenance during winter is essential to ensure your battery safety and have it ready to use for the summer season.


Check your user manual for specific instructions.

  1. Regular maintenance, including watering and removing corrosion.  sea-care-battery-cleaner-protectant
  2. Disconnect the negative cable and wait a few hours before checking specific gravity or voltage. Hydrometer: check each cell; gravity should be 1.265 - 1.285. Voltmeter: 12.6V is the reading for charged batteries
  3. Disconnect terminals to remove all electrical loads from your batteries. 
  4. Ideally, trickle charge batteries or charge them monthly. Fully charged batteries are at low risk of freezing. Do not leave your battery on a trickle charger for long periods as you run the risk of explosion caused by boiling electrolyte. Today's batteries do best when charged using a marine "smart charger."
  5. Do not overcharge your battery.
