"There is no electricity near the boat"
Considering that there is no electricity, I would wait until it warms up and you can get some electricty.
Once you have electricity you have the option of using an "Eraser" or a heatgun/hair dryer.
The "Eraser" would actually work on a battery operated drill, but I don't know power to get everyone off.
