Cairns sits at a crossing point that shapes the decisions of every offshore cruiser heading north. It is the last Australian port with a full range of marine services before the Torres Strait, Papua New Guinea, Indonesia and the Pacific - and that fact alone explains why the anchorage in Trinity Inlet is rarely empty during the winter sailing season. The marinas, boatyards, chandleries and service trades concentrated here give a departing yacht the same range of options found in a major southern capital, with the added weight that whatever you miss in Cairns, you are unlikely to find at the other end of the Coral Sea.
Australia's Northernmost Full-Service Marine Precinct
The description that consistently appears in cruising references - Australia's northernmost full-service marine precinct - reflects a practical reality, not marketing language. North of Cairns, available marine infrastructure drops sharply. Cooktown has a small marina with moorings and fuel, though marine repair services are very limited. Thursday Island has Ports North-managed port facilities with fuel available at the main wharf, but no marina or repair services for visiting yachts. Neither has a travel lift, a comprehensive chandlery, or trades that can commission electronics, service a liferaft or antifoul a sixty-foot ketch before an offshore departure.
What Cairns provides is the full stack: two marinas with shore power and fuel, four haul-out facilities with travel lifts of different capacities, hardstand storage, a major commercial slipway for the largest vessels, two chandleries covering both retail and industrial supply, and an on-call trade network covering mechanical, electrical, electronics, rigging and sail work. The concentration of this infrastructure in a compact geographic area is what makes the port work for offshore preparation rather than just transit.
The practical implication for a northbound passage is straightforward: Cairns is where you do the work. Even if cheaper haul-out rates were available further south at Mackay or Airlie Beach, a yacht arriving in June or July with a Torres Strait transit in mind needs to treat Cairns as the final opportunity to fix problems, upgrade systems, complete safety checks and load provisions for an extended offshore leg.
Navigating Trinity Inlet
Trinity Inlet is a well-marked commercial shipping channel and the approach is straightforward in daylight. The main channel carries substantial commercial traffic including cruise ships and bulk carriers, so give ship traffic right of way and monitor VHF 16 on approach. The yacht anchorage designated for visiting vessels lies directly opposite Cairns Marlin Marina on the inlet's western shore, putting anchored crews within dinghy range of the marina precinct and the city. The holding in the dark mud bottom is generally reliable if adequate scope is used, though the tidal current in the inlet runs strongly.
Ports North maintains a set of pile moorings inside Trinity Inlet, available to vessels up to a specified maximum length - confirm current size limits and fees directly with Ports North via portsnorth.com.au, as these are subject to revision. The moorings sit between the anchorage and the marina, offering an alternative to swinging at anchor for boats that fall within the size limit.
Anchoring in the inlet has historically been free, but Ports North policies on anchorage duration and charges have changed in the past. Confirm current rules with the marina office on arrival or via portsnorth.com.au before assuming long-term anchorage is available without charge.
Cairns Marlin Marina
Marlin Marina is the main public marina in the Cairns city centre precinct. Operated by Ports North, it holds more than 260 berths and can accommodate vessels up to 140 metres in length. The range means the marina handles everything from cruising monohulls to superyachts in the same precinct, and the management has experience with large vessels that most regional marinas lack.
Booking and Peak Season Timing
A minimum 48-hour advance booking is required before arrival, and in practice this is a floor, not a ceiling. The marina is in year-round demand. During the main cruising season from July through October, berths fill well ahead as northbound yachts cluster before the weather window for Torres Strait passages. Contact the marina weeks before arrival in peak season, not days. Reach Ports North via portsnorth.com.au for current availability and rates.
Shore Power, Fuel and Services
- All berths include single-phase 15A shore power in the berth fee; for vessels running larger loads during refit - battery charging banks, power tools, watermakers - three-phase power up to 200 amps is available at specific berths on request.
- Potable water is supplied at every berth.
- A fuel dock within the precinct supplies both diesel and petrol.
- A sewage pump-out facility operates inside the marina.
Marlin Marina suits pre-departure preparation that relies on city-centre access - provisioning, crew changeovers, customs and biosecurity clearance formalities, and trade visits where you need contractors to come to the boat. It is not a haul-out facility; for any out-of-water work, the vessel moves to the Portsmith precinct or Rum Jungle Marine.
Half Moon Bay Marina at Yorkeys Knob
Twenty kilometres north of the CBD, Half Moon Bay Marina sits inside the suburb of Yorkeys Knob. The drive from the Cairns airport takes roughly fifteen minutes; the drive from the Portsmith boatyards takes around twenty. This geographic separation from the main marine precinct is both Half Moon Bay's limitation and its appeal.
The marina accommodates vessels from ten to twenty-five metres with Comsen power and water pedestals at every berth. It operates a fuel dock and dry storage for smaller vessels, and - importantly - has mechanical and electronics trades based on-site rather than requiring crew to arrange contractors to visit from elsewhere in Cairns.
The practical case for Half Moon Bay over Marlin Marina comes down to what the vessel needs. Crews wanting a quieter environment, arriving from the north with a boat that fits the size range, or specifically needing the on-site trades will find it a workable base. Crews who need proximity to the Portsmith boatyards or the city centre for provisioning and clearance formalities will find the twenty-kilometre separation adds friction to daily logistics.
The Portsmith Marine Precinct
Portsmith is an industrial suburb a few kilometres south of the Cairns CBD, sitting on the main shipping channel immediately adjacent to HMAS Cairns. It is where the practical work of offshore refit happens in Cairns. The concentration of yards and suppliers here is not an accident - channel access, available industrial land and an established trade network have drawn marine businesses to the same streets over decades.
The key practical fact about Portsmith is that the two principal travel lift yards, the main commercial slipway, and the two principal chandleries all sit within the same compact industrial cluster. A crew can haul in the morning, walk to the chandlery for parts, and return to the boat the same afternoon.
Cairns Cruising Yacht Squadron (CCYS) and The Big Boat Shed are on the same street. Nautical Supplies (AMI Group) and Sharplift Marine and Industrial Supplies are within the same industrial pocket. Tropical Reef Shipyard operates the commercial slipway and a 300-tonne travel lift nearby.
Planning a Portsmith Work Week
- Contact CCYS or The Big Boat Shed to schedule your haul-out date and confirm lift availability; for large or unusual vessels, describe the vessel's keel configuration and beam in advance so the yard can plan sling placement.
- Book Marlin Marina for the nights before the haul - the short water transit from Marlin Marina to Smiths Creek basin keeps logistics simple on haul-out day.
- Prepare a full parts list before arriving and email it to the chandleries so you know what is in stock and what needs ordering; some items will take several days to arrive from the south.
- Coordinate contracted trades - antifoul painters, engineers, riggers - around the haul-out date so work overlaps rather than queues sequentially.
- Allow buffer days; weather, parts delays and discovered defects are the norm during offshore preparation, not the exception.
Haul-Out Facilities: Which Yard for Which Vessel
| Facility | Lift capacity | DIY policy | Best suited to |
|---|---|---|---|
| CCYS (Cairns Cruising Yacht Squadron) | 40 tonnes | Explicitly welcomed | DIY cruisers, club members, budget-focused haul-outs |
| The Big Boat Shed | 35 tonnes | Available - confirm with yard | Vessels with painted or delicate topsides; boats needing covered storage |
| Tropical Reef Shipyard | 300-tonne travel lift; commercial slipway to 3,000 tonnes | Commercial focus | Larger commercial and working vessels; contact the yard to confirm suitability and rates for recreational yachts |
| Rum Jungle Marine | Monohulls to 65 ft / 55 t; cats to 55 ft / 25 t | Contact yard directly | Catamarans, larger monohulls, extended cyclone-season storage |
CCYS in Detail
CCYS at Portsmith operates a 40-tonne travel lift with a hardstand holding up to 75 vessels. The yard also has a marina with a small number of berths and pile moorings, which means a boat can wait on a mooring, haul for work, and return to a berth without relocating to a different facility. The explicit DIY welcome is significant: many commercial boatyards in Queensland restrict owner-performed work to avoid liability and protect their own trades. CCYS's approach makes it the natural choice for offshore cruisers who want to do their own antifouling, osmosis work or minor repairs during a week or two on the hardstand.
Noonsite reports that haul-out costs in Cairns - hardstand plus the full lift cycle - are substantially higher than at comparable facilities further south in Queensland, with the gap large enough to influence whether cost-sensitive cruisers do major work here or at Mackay before heading north. Check current rates directly with the yard and read recent Noonsite reports at noonsite.com for a realistic budget figure before committing to Cairns for extended out-of-water work.
The Big Boat Shed in Detail
The Big Boat Shed runs a 35-tonne Marine Travellift fitted with fabric slings rather than wire. Fabric slings distribute load across a broader contact area, reducing pressure on painted topsides and hull fittings - a material advantage for glass or timber boats with epoxy coatings, or yachts with through-hull fittings positioned awkwardly relative to standard sling placement. The yard draws boats from Smiths Creek, a basin sitting around five minutes by water from Marlin Marina. Storage options include open hardstand, undercover shed space, and a portable covered structure called The Igloo for boats needing weather protection without the cost of full shed space. Total storage capacity reaches up to 75 vessels across all options.
Rum Jungle Marine at East Trinity
East Trinity sits across the inlet from the main Cairns precinct. Rum Jungle Marine handles monohulls up to 65 feet and 55 tonnes, and - critically for multihull owners - catamarans up to 55 feet and 25 tonnes. Neither CCYS nor The Big Boat Shed is specifically configured for wide-beam catamaran haul-out; Rum Jungle is the clearest option for a catamaran needing out-of-water work in the Cairns area. If your beam is at the outer edge of the stated limit, contact the yard before making plans - confirm the current lift configuration and sling spacing will suit your hull.
The haul-out fee includes a pressure clean of the hull, removing the step of separately scheduling hull cleaning before antifoul application. Short-term storage runs to a fixed cap of three months; long-term storage is calculated by vessel dimensions per day. For boats planning a cyclone-season lay-up rather than a quick refit turnaround, the dimensional pricing model means costs scale with the boat's footprint - get a written quote early and compare it against other regional storage options. The East Trinity location sits outside the Portsmith walking-distance chandlery cluster, so factor in transport time for parts and trade visits when scheduling work.
Chandleries and Marine Supplies
Two suppliers in the Portsmith precinct cover the range of offshore equipment needs, with clearly different strengths.
Nautical Supplies (AMI Group)
Nautical Supplies, part of the AMI Group, in Portsmith, is the principal retail chandlery serving offshore cruisers. The stock covers the main categories a departing yacht needs to audit before an offshore passage:
- Electronics: Simrad, Raymarine and ICOM chartplotters, VHF radios, AIS transponders and ancillary hardware
- Deck hardware: Ronstan and Wichard blocks, shackles and running rigging fittings
- Safety equipment: Plastimo and ACR EPIRBs, flares, harnesses and tethers
- Life raft servicing and inflation testing on-site
- Life jacket inflation and service checks on-site
The life safety servicing capability is worth flagging separately. AMSA compliance for offshore passages requires current service records on EPIRBs, life rafts and life jackets. Having a facility that can test, service and certify this equipment alongside the main chandlery stock means compliance checks and any necessary replacements can happen in a single visit rather than requiring separate appointments across town.
Sharplift Marine and Industrial Supplies
Sharplift, also within the Portsmith precinct, supplies the industrial end of the marine market - commercial-grade fasteners, mooring hardware, industrial hose and fittings. For offshore vessels built or maintained to commercial or AMSA standards, the distinction matters: Sharplift carries the grade of hardware that retail chandleries typically do not stock. Through-hull fittings, heavy stainless fasteners, high-pressure hose assemblies and mooring chain components are the kind of items to source here rather than from a retail counter.
