there is no tide where the boat will be and it's not salt water.
when ice thaws, it is expending then causing breakage?
For ice-build up (accumulation of ice), I noticed they were next to the shore, not at 100 feet of it.
Howewer I think I will get some kind of device the prevent ice, at least the first year and make some tests without the boat in the water.
Rob, I understand ice-eater is working for you in 4 feet of water. Is a ice-eater same thingh as a bubbler or it's different type?
