How does everyone split the cost of a group yacht charter?

Most groups split the cost of a yacht charter by cabin, not by headcount: one person signs the contract as the charterer, and everyone else pays their share before the deposit is due. Per-cabin math is fairer because cabins differ: the master suite typically carries a 10–20% premium over the smaller doubles. Budget the full number first. A $30,000 base rate for eight guests looks like $3,750 each, but crew gratuity of 15–20% pushes the real figure past $4,400: on all-inclusive Caribbean catamarans, meals and the bar are already in the base, so surprises stay small. Collect funds up front. The charterer is legally responsible for the entire balance, so a payment app pool beats chasing friends after booking. The group charter planning guide covers deposits, timelines, and cabin assignments.
