How long can a dog “hold it” and still be comfortable?
Each pet is different. In general, a dog that is moving around actively can go about 4 to 5 hours in between toileting. If a dog is resting and calm this period greatly increases (such as overnight, or 8 plus hours). During your sailing, your dog will either be in your vehicle in a quiet area of the ship without any outside stimulus that might excite him to be restless, or he will be in his travel kennel in the kennel service area. Both options provide a restful atmosphere that should allow the pet to simply relax and sleep, thereby not needing to toilet as often as if he were having an active day.
