Castlecrag Marine

About Castlecrag Marine

Castlecrag Marine sits in the protected waters of Sailors Bay, offering a quiet Middle Harbour base with a marine-service history reaching back to 1910. The current operation blends boutique floating berths, swing moorings and a skilled slipway yard in a leafy residential setting. We think that longevity matters: this is a place built around knowing boats, owners and the particular demands of maintaining vessels on Sydney Harbour.

The marina’s floating berths provide power and water for vessels up to 60 feet. Secure swing moorings are available for short or longer stays, with storage for an approved fibreglass dinghy up to 2.4 metres and courtesy dinghies for access. A courtesy berth is normally available for loading and unloading. The governed profile carries indicative figures of about nine wet berths and 52 moorings, but current availability should always be confirmed directly.

Two slipways handle boats up to 35 tonnes, with published limits of 50 feet and 2.4 metres draft for the slipway operation. The yard’s qualified shipwrights undertake repairs, deck work and full restoration, with a recognised strength in classic timber cruisers and yachts. Painting, varnish, antifouling, detailing, surveys and routine servicing round out the offer. DIY slipping can be arranged, with vehicle access near the boat making owner-managed work more practical.

Sailors Bay opens into Middle Harbour, placing the Spit, Balmoral and Sydney Heads within an enjoyable run. The return to a protected, bush-edged bay feels worlds away from the busy main harbour. Shore facilities are more workshop and owner focused than visitor oriented, and the residential location rewards considerate access. What stands out to us is the combination of understated surroundings and genuinely substantial repair capability.

Our take is that Castlecrag Marine is particularly strong for owners who want a long-term relationship with a capable yard. Classic-boat custodians, hands-on DIY owners and Middle Harbour regulars should all find something to value. Confirm berth or mooring space, slipway geometry and the exact scope of work before arrival. For suitable vessels, it is one of Sydney’s most characterful and useful small marine facilities. Its calm scale makes regular ownership feel more personal and manageable.

Services

Castlecrag Marine offers boutique floating berths with power and water for vessels up to 60 feet, along with sheltered swing moorings for short- or long-term hire. Mooring fees can include storage for an approved fibreglass dinghy up to 2.4 metres, and courtesy dinghies are provided. A courtesy berth is normally available for loading and unloading, subject to operational needs.

Two slipways accept vessels up to 35 tonnes, with published slipway limits of 50 feet and 2.4 metres draft. Services include shipwright repairs, timber restoration, painting, varnishing, antifouling, detailing, servicing and professional hull surveys. Work pontoons can support larger repair tasks. DIY slipway bookings may be approved, with parking beside the vessel, but yard safety, insurance and environmental rules apply.

Provide full length, beam, draft, displacement and construction details when requesting a berth, mooring or haul-out. Ask for a written estimate covering slip fees, supports, pressure cleaning, materials, labour, lay days and relaunch. Confirm courtesy-berth timing, dinghy conditions, parking and after-hours access before arrival. Middle Harbour is sheltered, but current weather, navigation information and local traffic still belong in the passage plan.

Ideal for

Middle Harbour yacht and motorboat owners seeking a small marina with serious repair capability, especially custodians of classic timber boats and hands-on owners who may want approved DIY slipway access.

What we love

• A marine-service history in Sailors Bay dating to 1910.

To keep in mind

Published berth and mooring figures are indicative, so confirm current space directly. Slipway length, draft and weight limits differ from the larger work-pontoon capability. DIY work requires prior approval, insurance and compliance with all yard safety and environmental rules.
