RE: liveaboard new to this forum
We have three ice eaters around the boat . I would not like any ice around my hull.
I lived aboard for almost 23 years in the NYC area and never had the slighest problem with icing in.
The bubblers , even with a foam cored hull which is usually the quietest the air bubbles made the boat sound like a fish tank inside.
Harm from ice was common on wood boats as the first freeze would freeze the water , all the way into the cotton .
Any movement of the boat would start the cotton , but the ice would support the boat , till the thaw.
Hassles with liveaboards would come from thru hulls not deep enough , so the sink or toilet would stop.
The best fun was one year at the Worlds Fair Marina , when a fellow with a fine Huckins got a young babe that decided the boat was too spartan.
She chose nice pink toilet paper , which created a nice pink pile next to the boats head discharge which was above the WL a foot or so.
