Cancún Yacht Routes — Isla Mujeres, Isla Contoy, Cozumel Crossings

Why Cancún has three real routes, not a dozen

On paper, you could chart a yacht route to a dozen destinations from Marina Hacienda del Mar, Puerto Cancún or Marina Aquaworld. In practice, only three destinations make commercial and navigational sense on a charter day: Isla Mujeres (the easy default, 8 nautical miles north-east), Isla Contoy (the protected island ~35 nm north of Cancún, requiring CONANP permit), and Cozumel (~40 nm south, an open-water crossing that puts you on the Mesoamerican Reef wall). Every other "yacht trip" you see advertised is some sub-version of these three — Holbox is technically reachable but adds hours each way, El Meco reef is an Isla Mujeres sub-stop, and Puerto Morelos is a Cozumel-route variant.

The decision tree is shaped by three things: distance (which controls fuel and how much real water time you get), permits (Contoy is the gated one), and weather window (Cozumel crossings demand a clean forecast that the Cancún coast does not always provide in winter Nortes). A captain working a 4–8 hour day will almost always default to Isla Mujeres because the math works for any group size and any season. Contoy and Cozumel are deliberate decisions, not "let's see how the day feels".

The three routes side by side

Crossing time assumes a 50+ ft motor yacht at 18 knots. Sailboats double the times; high-speed cruisers (45+ kn) cut them in half but burn fuel proportionally. All three routes require a captain with current Capitanía de Puerto credentials issued by SEMAR.

Route 1 — Isla Mujeres: the workhorse loop

From any Cancún marina to Isla Mujeres is ~8 nautical miles across the channel that separates the island from the hotel zone. Most charters depart between 9 and 10 am, cross in 25–35 minutes, and pick one of three anchor zones: Playa Norte (sand bottom on the north end, swimmable straight off the swim platform, the default for groups that want to drift in the shallows), MUSA Underwater Museum (the sculpture installation that doubles as a snorkel field — buoys on the south-west side, depth 4–8 m), and Manchones Reef (the south-end reef system, deeper and richer marine life, buoys at the dive zones).

Most 4-hour charters do one stop — usually MUSA. Six-hour charters do two — MUSA plus a lunch stop in town or anchor at Playa Norte. Eight-hour charters add Manchones and a longer swim block. The crossing is sheltered by the lee of Isla Mujeres itself, so even moderate north winds keep the route workable; in our experience, Isla Mujeres routes complete as planned more than 90% of charter days.

Dock fees apply if you tie up in the Isla Mujeres marina (~$20 USD per guest), and a small CONANP fee applies if you anchor in the Parque Nacional Costa Occidental de Isla Mujeres zone (~$5–8 USD). Reputable operators invoice these as line items rather than rolling them into base. For the full breakdown of how this day flows, see our Isla Mujeres yacht day guide.

Route 2 — Isla Contoy: the protected gem

Isla Contoy sits ~35 nautical miles north of Cancún, just past Isla Mujeres in the Yucatán Channel. It is a federally designated national park administered by CONANP — the same agency that runs Cabo Pulmo and Banco Chinchorro. The protection level here is serious: the island hosts nesting colonies of frigatebirds, pelicans, cormorants and seasonal sea turtles, and the surrounding seagrass beds shelter juvenile reef species. The daily visitor cap is ~200 people across all authorised operators combined, enforced by the park ranger station on the south end of the island.

To run a yacht charter to Contoy, the operator must hold a current CONANP concession, the trip must include a federally certified biologist on board for the landing, and the route plan must be filed with the local SEMAR Capitanía. Not every Cancún yacht has these papers — and the ones that do typically only run Contoy days a few times per week because the permits cap them too. Expect a 9–10 hour day minimum: 2 hours north, 4–5 hours on the island (a guided walk on the boardwalk, snorkel at the lee anchorage, lunch), 2 hours back.

Anchorage on Contoy is restricted to a designated mooring zone on the south-west lee — directly anchoring on the seagrass or reef is prohibited and SEMAR patrols enforce it. The biologist briefs guests on land rules before disembarking: no removing shells, no feeding wildlife, no sunscreen with oxybenzone in the snorkel zone (CONANP follows reef-safe sunscreen guidance aligned with IMO MARPOL environmental annexes).

Route 3 — Cozumel crossing: the long open-water day

Cancún to Cozumel is ~40 nautical miles roughly south-south-east, the open-water crossing that puts you on the wall of the Mesoamerican Reef. This is the longest of the three real routes and the only one that crosses a busy commercial shipping channel administered by APIQROO (Administración Portuaria Integral de Quintana Roo). Cruise ships, ferries from Playa del Carmen, and cargo movements all use the same water; a captain working this route files crossing intent with the local port authority and times the run to avoid the worst of the cruise-ship traffic windows (typically 6–9 am arrivals and 4–6 pm departures on Cozumel).

Cruise time at 18 knots is ~2 hours 15 minutes each way. That eats 4.5 hours of a 10-hour day in transit alone, leaving 5.5 hours on Cozumel — enough for one or two snorkel stops (Palancar reef shallow zone on the south-west side, or Chankanaab reef on the south-central coast) and a quick anchor lunch. For real Cozumel time, this route works better as the front half of an overnight charter — depart Cancún 9 am, anchor at Chankanaab overnight, snorkel Palancar at dawn, return next afternoon. See our 2-day Cozumel overnight itinerary for the full plan.

Cozumel days demand a clean weather forecast. Winter Norte winds of 20+ knots make the crossing rough on anything under 50 ft, and the return leg in the late afternoon is often choppier than the morning out. The captain checks the NOAA NHC tropical outlook in summer and Mexico's SEMAR Atlantic forecast all year before committing. If conditions sour, the day pivots to a long Isla Mujeres + El Meco reef variant.

Anchor points and reef rules — where you actually drop the hook

Every route ends with the same question: where does the boat actually stop? Mexican federal regulations and CONANP zoning prohibit anchoring on living coral anywhere in the Caribbean Marine Park system. Reputable operators only use designated mooring buoys or sand-bottom anchorages identified on official charts. Here is the legal anchor list:

• Isla Mujeres — Playa Norte: sand bottom, 3–5 m depth, anchor permitted outside the swim-zone buoys.
• Isla Mujeres — MUSA: mooring buoys only, 4–8 m depth, ~30 buoys total managed by the Marine Park concession.
• Isla Mujeres — Manchones: dive-class buoys on the reef perimeter, 8–15 m depth.
• Isla Contoy — Punta Sur lee: 12 designated mooring buoys, biologist supervises hook-up.
• Cozumel — Chankanaab: sand bottom in the inshore bay, 4–6 m, anchor permitted; reef buoys at the snorkel zone.
• Cozumel — Palancar shallow: drift snorkeling preferred over anchor; if anchored, sand patches on the leeward side only.

The rule of thumb is simple — if your captain points to coral and lowers the anchor, you are on the wrong boat. Active SEMAR patrols and CONANP enforcement teams check anchorages routinely in peak season, and the fine for coral anchoring runs 50,000+ MXN plus licence suspension. US Sailing and IMO have aligned best-practice guidance on reef-safe anchoring that the Mexican Navy now enforces directly.

Fuel range, cruising speed and the "fuel-heavy day" surcharge

Most Cancún charter yachts in the 40–60 ft range cruise economically at 15–18 knots and burn 80–140 litres of diesel per hour. The base charter rate typically includes a "reasonable" fuel allocation tied to the standard Isla Mujeres day; routes that exceed that allocation invoice a fuel surcharge at marina pump price. Diesel at Marina Hacienda del Mar in early 2026 was running ~$1.30–1.50 USD per litre — the API CANCÚN (APIQROO) publishes the official daily rate that operators must use as the baseline. A Contoy day adds typically $180–400 USD of fuel over baseline; a Cozumel round-trip day adds $400–800 USD; an overnight Cozumel charter doubles that again.

The fuel surcharge is one of the most common contract-fine-print surprises for first-time charter clients. Reputable operators quote it upfront when you select the route; less reputable ones present it at the dock at departure. We cover the full list of common surcharges in our Cancún yacht charter contract fine-print article. Read that before signing anything for Contoy or Cozumel — those two routes are where the price gap between "advertised base" and "actual day cost" is biggest.

Weather windows — what closes which route, and when

The Cancún coast operates on a relatively predictable seasonal weather pattern, but each route has its own threshold for cancellation. Isla Mujeres handles winds up to ~22 knots before captains start refusing to cross; below that, the lee of the island shelters the day. Isla Contoy needs a calmer window — 18 knots maximum on the run north, because the leg past Isla Mujeres opens into the Yucatán Channel proper where there is no lee. Cozumel is the most demanding: north winds above 20 knots make the crossing uncomfortable on anything under 55 ft, and tropical wave activity (May–November) can force cancellation with 6 hours notice.

The reference forecasts are the NOAA National Hurricane Center tropical outlook (May–November), the SEMAR Capitanía de Puerto Cancún daily bulletin (year-round), and the CONAGUA regional weather forecast. Captains read all three before committing to a Contoy or Cozumel day. If you are booking in advance for these routes, build a 24-hour reschedule buffer into your trip — most operators allow a one-time free reschedule for SEMAR-declared port-closure days.

Which route is right for your group

The simplest decision rule: first-time visitors and mixed groups → Isla Mujeres. The crossing is short, the day is forgiving, the anchorages have variety (sand, museum, reef), and the route survives most weather. Couples and small groups can do this on a 30–35 ft boat; bachelor/bachelorette parties hit the sweet spot on a 45–50 ft yacht. See our bachelor / bachelorette yacht planning guide for the celebration angle on this route.

Nature-focused groups and serious snorkelers → Isla Contoy. The trade-off is the longer day, the permit cost, and the strict rules — but Contoy is the only Mexican Caribbean destination where you get a federally protected nesting-bird island plus reef snorkel in one charter. Book this 4–6 weeks ahead to ensure permit availability.

Reef divers and overnight charters → Cozumel. A single-day Cancún→Cozumel→Cancún is technically possible but doesn't give you enough water time to justify the fuel. The honest pitch is to do it as a 2-day overnight (see the linked itinerary above) or, alternatively, fly/ferry to Cozumel directly and charter from there — see our Riviera Maya yacht routes article for the Cozumel-based version of this charter.
