One "draw back" of the Owner's Version(3 cabin) is that the owner's hull is so disproportionately bigger than either other stateroom, then the other guests may resent it. Just have a upfront method to dealing with this issue: Upon organizing trip "cabin assignment in order of commitment to trip (ie deposit received)" or lottery.
Ocean Song:
I put quotation marks around "draw back" only to say owners version has one "Master Suite" and it is nice and even more spacious than the 4 cabin models... as intended.
When chartering ANY boat, it is good to have system of assigning berths via lottery, order of deposits, or having variable rates for the various cabins. If Mom and Dad are with the kids, No problem.... MOM gets the owner's suite and Dad joins her there if she allows him.
