On FRS you can use up to 2 watts on 1-7 or 15-22. The middle 8-14 are limited to .5 watts. I don't know that specific model so I don't know if it has the type 95 sticker on it. You can try looking it up on the FCC site but since there are so many rebrands sometimes that it tough. In theory that would work as long as you either kept power to .5 watts and only turned up to 1 watt on 1-7 or 15-22.
These are what I bought to play Walkie Talkie with the kids. They want to play with my Ham radio and that's not going to work. But these Baofeng are .5 watt FRS so fine for us to use on any channel (you just lose the overall range).
And these are in the local Target. I could pick them up whenever. I'm not sure of their specs but I'm guessing they are .5 watt as well.
It's worth noting that the FCC changed the regulations late last year to simplify the FRS/GMRS split. Basically you can use FRS radios on all channels now, but are power limited. You can't have a removable antenna or use repeaters without a GMRS license but you don't need that on the ship. So you'll find many "walkie-talkies" are low power. I'd like to a find a new FRS radio which was 2 watts on 1-7, .5 on 8-14, and 2 again on 15-22 but I don't think they exist yet.
