Let the battery sit in the basement for a week.
Charge it with a trickle charger until the charger light turns green.
Unplug the charger, let it sit overnight then measure

Would that work?
The goal I had in mind was to test your boat's charging system, not the battery. Charge the battery fully and then bring it to a store that sells batteries, they will load test it for you and determine if it is good or not. Once you have a known good battery in your boat, try my test after a day of boating and see if the battery is fully charged. If it is great, if not, you should address it to avoid being stranded on the lake someday...
