You can prepare the rib eyes sous vide at home and bring the down frozen. Thaw in fridge and reheat on bbq, just down go higher than the original target temp.
My issue has always been 2 fold.
1) fresh water used for the bath, unless you have a water maker as scuba doo does.
2) what container would you use to cook the rib eyes in?
Warren S/V Scuba Doo Lagoon 50 (winner of best crewed yacht under 55 feet at the St. Thomas crewed yacht boat show).
