The short answer
- Sailing boats carry fewer people than motor catamarans, and that changes the day more than the sails do.
- Michaelmas Cay is the classic sailing destination — a sand cay and bird sanctuary on the reef.
- Expect $280–$289 per adult, similar to a motor boat but with far fewer passengers.
- You trade reef sites for atmosphere. Sailing is slower, so you visit fewer moorings.
- Best in light winds. In the June-to-September trades you'll motor more than you sail.
Most reef trips from Cairns are fast motor catamarans carrying a lot of people to a lot of sites. A handful of operators sail instead, and it's a genuinely different day for roughly the same money.
Whether it's the better day depends on one question: do you want more reef, or a better time getting to it?
Why sail rather than motor
The romantic answer is the sails. The real answer is passenger numbers.
Sailing catamarans here typically carry far fewer people than the big motor boats, and that changes everything about a reef day: shorter queues at the gear station, no waiting at the ladder, smaller guided snorkel groups, and crew who learn your name. We've argued elsewhere that passenger count is the most under-asked question in reef booking — see how to choose a reef tour.
The sailing itself is a real bonus rather than the point. Engines off, the boat heels slightly, and the two hours to the reef stop being dead time. On a motor catamaran the crossing is something to be endured; under sail it's part of the day.

Michaelmas Cay
The destination that makes sailing from Cairns distinctive.
Michaelmas Cay is a sand cay on the reef — a low island of coral sand sitting on a reef platform, and an important seabird nesting sanctuary. Thousands of birds nest there, which means visitor access is restricted to a marked section of beach to protect them.
What that gives you is unusual: you snorkel off a beach in the middle of the ocean, with fringing reef right there, and a wall of noise from the bird colony behind you. It's nothing like a pontoon and nothing like a mooring in open water.
The restriction is also the point — you can't wander the cay, and you shouldn't want to. Our Michaelmas Cay page compares the operators that go there.
The sailing operators
| Operator | Adult | Child | Departs | Where |
|---|---|---|---|---|
| SeaStar Cruises | $280 | $180 | 7:30am | Michaelmas Cay and Hastings Reef |
| Ocean Spirit Cruises | $288 | $149 | 8:30am | Michaelmas Cay |
| Ocean Free | $289 | $225 | 8:00am | Green Island, with its own private mooring |
| Passions of Paradise | See tour page | — | Morning | Outer reef, sailing catamaran |
Adult from-prices per our tour pages. Family fares available on several; add-ons such as dives are extra.
Choosing between them:
- SeaStar is the highest-rated of the group and visits two sites — Michaelmas Cay plus Hastings Reef — which is unusual for a sailing day. The 7:30am departure is early, and that's what buys the second site. See SeaStar.
- Ocean Spirit has the best child fare of the three at $149 and a family price, which makes it the sailing option for families. It also offers a marine biologist guided snorkel as an add-on at $89, and introductory diving from age 12. See Ocean Spirit.
- Ocean Free sails to Green Island and has its own private mooring there, which means you get the island without the crowd that arrives on the big catamarans. Different proposition — more island, less outer reef. See Ocean Free and our Green Island guide.
- Passions of Paradise is a sailing catamaran running to the outer reef, and it's the one to look at if outer reef coral matters more to you than a sand cay.
What you give up
Being straight about this, because the sailing brochures aren't.
| Sailing | Motor catamaran | |
|---|---|---|
| Passengers | Far fewer | Often 100+ |
| Reef sites | Usually one, sometimes two | Two or three |
| Crossing | Slower — part of the day | Faster — more time in the water |
| Time at the reef | Less | More |
| Facilities | Basic | More, including dry viewing on pontoons |
| Atmosphere | The main reason to book it | Functional |
| Price | $280–$289 | $275–$330 |
The honest summary: you're paying similar money for less reef and a better day. If your priority is maximum coral, book Silverswift at $308 and get three sites. If your priority is not spending eight hours with a hundred strangers, sail.
The early departure is worth taking seriously. SeaStar's 7:30am start is an hour ahead of most boats, and it's the reason it can fit two sites into a sailing day. If you're not a morning person, Ocean Spirit's 8:30am is the gentler option.
Who sailing suits
- Couples and anyone allergic to crowds. The single strongest case.
- People who like boats. Obvious, and worth saying — if the vessel is part of the appeal, this is the only reef format that delivers it.
- Nervous snorkellers. Smaller numbers mean more crew attention and a less chaotic ladder. A sand cay entry is also gentler than open water. See is snorkelling the reef safe.
- Families, on Ocean Spirit specifically, because of the $149 child fare and the family price.
- Not for divers chasing sites. One or two moorings won't satisfy a certified diver — see our diving guide.
- Not for non-swimmers. Sailing boats have no glass-bottom boat or semi-submersible. Book a pontoon instead — see the reef for non-swimmers.
Best conditions for a sailing day
One caveat that operators don't advertise: in strong winds you'll motor. The south-easterly trades are strongest from June to September, and while that sounds ideal for sailing, in practice heavy conditions mean engines on for safety and comfort.
The best sailing days are the lighter-wind months — roughly October to April — when there's enough breeze to sail and not so much that it's uncomfortable. That's also when the water is warmest. The month-by-month reef picture is in snorkelling the reef month by month.
Whatever the month, a smaller boat moves more than a big one. If seasickness is a concern in your group, a pontoon is the steadier choice.
Prefer forty people to a hundred?
Sailing days cost roughly what a motor catamaran costs and carry a fraction of the passengers. We'll tell you the numbers booked on your date before you commit.
Compare reef tours →How we know this
We book all of these boats, and the comparison reflects what guests report back rather than what the brochures claim. Every price, departure time and inclusion comes from the operator's own tour page. Where a figure isn't published, we've left it out.
Whether a boat sails or motors on any given day depends on conditions. Passenger numbers vary by date and we confirm them at booking.
Sailing to the reef: our verdict
Roughly the same money as a motor catamaran, fewer reef sites and a much better day — and the reason is passenger numbers, not sails. SeaStar at $280 is the highest-rated and squeezes in two sites off a 7:30am start. Ocean Spirit at $288 has the best child fare at $149, so it's the family sailing option. Book it if you'd rather share a boat with forty people than a hundred; skip it if you're a diver chasing sites or you need dry viewing options.
