For someone wanting to claim their boat as a second residence, is the following true regarding the use test:
Second Home Requirements
If you don't rent out the boat at all, you don't have to satisfy the personal use requirements. However, renting it out for just one day triggers the use requirements. If you rent it out, you must use it for the longer of 14 days or 10 percent of the number of days you rent it out. For example, if you rent it out for a week, you have to use it for at least 14 days during the year for it to qualify. Alternatively, if you rent it out for 160 days, you have to use it for at least 16 days to qualify.
The boat has sleeping, cooking and toilet facilities, the boat so it counts as a home, according to IRS Publication 936. I'm just curious on the use test.
Thanks!
