Neptun 27 Buyer's Guide
Shopping the brokerage market for a Neptun 27 means looking at a 1973-origin German-built cabin cruiser that still turns up across the inland and continental European market. She is a 26.7-foot masthead sloop with solid fiberglass construction and a choice of fin or daggerboard keel, which matters more than almost any cosmetic detail when you evaluate a specific boat.
Layouts on the Used Market
The Neptun 27 was built with different keel alternatives, and the fin-keel version draws about 4.1 to 4.4 feet while the daggerboard model sits at roughly 2.1 to 2.4 feet dependent on load. Below, the boat is equipped with five berths and headroom near average for the length, a layout consistent with her cabin-cruiser purpose. Because the hull was also offered with different engine alternatives, you will find some boats with an inboard and others set up with an outboard for docking and maneuvering.
Equipment and Common Upgrades
On the used market, solar and an inverter are commonly fitted, supporting house power at anchor without engine runtime. Beyond those, the most consequential buyer-side equipment centers on propulsion and control: an outboard of 3 to 4 hp or an electric motor of 75 to 90 lbs thrust is typical for close-quarters handling, and the masthead rig carries 3/8-inch sheets throughout — jib and genoa at 27.7 feet, mainsheet at 69.3 feet, spinnaker at 61 feet — so verify running rigging condition rather than assuming upgrades.
What to Inspect
The wetted bottom surface of the Neptun 27 is about 215 square feet, a meaningful antifouling and blister-inspection area on a solid fiberglass hull wetted bottom surface. Confirm which keel type is fitted and whether the daggerboard trunk or fin attachment shows stress, since the two drafts differ by nearly two feet. Check the engine installation type — outboard well versus inboard — and match it to the stated docking power needs.
Availability and Buyer's Takeaway
These boats typically appear in the Netherlands, Switzerland, Germany, and France. For a buyer, the short list is: confirm keel type and draft, verify berth count and headroom in person, inspect the 215 sq ft wetted bottom for gelcoat issues, and confirm the solar and inverter house-power setup.
