Question:
I keep my 30’ cruiser on a lift over winter. Would the 800W heater handle it, or should I double up?

Expert Reply:
John, lift-stored boats lose heat faster than those in the water, so you’re smart to ask. The 800W # XH27FR is the recommended size for 30–35’ boats, but in lift storage, many owners either add a second 400W # XH67FR or 600W # XH77FR heater or go with two 800W units if the compartment is large. You’ll also help it perform by covering vents and outdrives to cut cold airflow.
Do you have access to shore power on your lift, or do you rely on a portable generator?

I’ve got shore power, but it’s an open dock and gets windy. The bilge has twin engines, so I’m thinking two heaters might make more sense. Have you heard of anyone running a pair of 800W units without issues?
