Lived aboard a 37 foot sportfish in Annapolis
2 years, 98-99.
Loved every minute of it....well except for maybe 2 nights when the temps were in the teens and the winds howling.
3 space heaters usually kept it comfortable...even with the drafty all glass main salon
. One year I went crazy and stuffed foam in every crevice and put the 3M window film over all the windows (clear heat shrink stuff)...it was well worth the effort because the second winter I was lazy and didn't...some nights it would have been worth it.
Walking to the showers barefoot through the slush was a great way to wake up even before my coffee! .... but that probably was related to my idiotic love of the years I spent on polar icebreakers!!!
Some issues are marina related and some are boat issues...obviously it all comes down to what YOU can live with. There are great blogs and articles out there about living aboard
in Chicago and points worse...and I can't imagine those winters.
Sailboats are probably easier than a sportfish as more boat is in the water
and the water tanks
can live down deep...my tanks
would have froze some weeks so I had a camping 5 gallon container for everything except showering. I've also lived aboard a 30 foot sailboat...but in Ft Lauderdale...so winter was less of an issue.
Living aboard is worth almost every difficulty...but then again...after 4 military survival schools..I may not be the right person to ask!
