The most expensive mistake in chartering is not overspending. It is booking a 120-footer for six people who wanted to swim, or a 40-footer for twenty people who wanted to be served. Size is a tool, and this is the guide to matching it to the weekend.
We hear the same eight questions from nearly every guest deciding between a day boat and something with a crew list. Here they are with straight answers. Ranges are typical for Miami and are not quotes.
How many people are coming, really?
Count the group before you fall in love with a boat. Day boats in the 35 to 45 foot range are certified for six to twelve and comfortable for eight. Motor yachts of 60 to 80 feet handle twelve comfortably and are often capped at twelve by law for charter. Above that number you are into superyacht territory or a vessel inspected for larger parties, which is a different license and a different price. Eight friends: day boat. Twenty colleagues: start big.
How many hours do we actually want?
Four hours is a complete day on a day boat: sandbar, swim, lunch, home. On a 70-footer four hours feels like an appetizer, because the boat takes time to go anywhere and the point of the size is the lunch at anchor. If you want the full arc, morning sandbar, lunch, golden hour, plan eight hours, and know that on the larger boats the eight-hour rate is rarely double the four.
Are we sleeping aboard?
Overnight settles the question by itself. Day boats do not do it. Motor yachts of 60 to 80 feet can, with two to four cabins and a crew of two or three, and a night at Elliott Key or across to Bimini is one of the great things this coast offers. Superyachts are built for it, with a chef, stewards and cabins that feel like a hotel. If the weekend includes a sunrise from the water, size up.
What is the honest budget?
A day boat afternoon starts around $1,000 to $1,800. A mid-size motor yacht day runs $6,000 to $13,000 for eight hours once you include the boat and crew. A superyacht day starts north of $15,000 and climbs quickly, and the invisible lines, fuel, gratuity, provisioning, add 40 to 70 percent on the larger tiers. We laid the whole thing out in The Honest Breakdown.
Do the toys matter to us?
Day boats carry floats, a paddleboard, snorkel gear, sometimes a jet ski for a fee. Motor yachts add a tender, a Seabob or two, an inflatable platform off the stern. Superyachts carry a garage. If your group is adrenaline-first and under forty, the toys decide the day and a well-equipped 70-footer often beats a bare 100-footer. If the group is content with a swim and a good lunch, do not pay for a garage you will not open.
Are there kids, and how old?
Children under ten do best on a boat with a swim platform at water level, shade you can sit under at noon, and an inflatable platform off the stern that becomes the day's entire agenda. That points to a motor yacht with a real crew, because someone will have eyes on the water the whole time. Teenagers are happier on a day boat with a jet ski than on a superyacht with a formal lunch, which surprises parents every time.
Is this a corporate event?
For a leadership team of eight to twelve, a 70 to 80 foot motor yacht with a flybridge is the sweet spot: one working session in flat morning light, a destination lunch, the strategic conversation on the upper deck at four. For a client event with forty guests, a superyacht or a vessel inspected for larger groups is the only honest option, and the crew becomes the catering staff. We covered the format in the corporate charter piece.
Do we want photographs or an experience?
Say it out loud; it changes the answer. The photographs everyone frames are taken from a flybridge with the skyline behind, which means a motor yacht or larger. The experience most people remember is the swim at the sandbar and the lunch at anchor, which any size delivers. If the weekend is a proposal, an anniversary or a milestone birthday, the extra deck is worth it. If it is a Saturday with friends, the day boat wins on every measure that matters at the sandbar.
The pattern across all eight is simple. Size follows the group, the hours and the occasion, in that order, and never the other way around.
Filter by length, capacity and what is aboard, then let the weekend choose. Explore the fleet.
