Seahorse yachts 52 cruising

Seahorse 52

Base Price: $640,000

Pilothouse Design Longrange Cruiser Trawler yacht, twin diesels, well equipped.

With an unbeatable price, this beautifully strong yacht of 52′ LOA features a plus 2′ swim-boarding platform and large wide body main saloon aft.

The design includes two queen-sized cabins, including two heads — one with a tub and another with a separate shower. Interiors can be teak or cheery wood and all windows comprise powder coated aluminum frames with screens, while the pilothouse windshields are 10 mm thick.

She’s able to exceed the 9 knot hull speed by a several knots because of its lighter fiberglass hull, and, as you might expect, she efficiently uses fuel at a standard 7-to-9 knots.

With safety first, designers include a dash safety systems monitor. You’ll know the status of each system in the boat, including high engine room temperature, engine water flow, bilge water status, and if any pumps are running. Should something become abnormal, the monitor responds with visual and audio warnings.

Since more than 20 Seahorse 52 yachts now are delivered, Seahorse Marine has incorporated response from owners to make a good boat an even greater passagemaker. This feedback produced many matchless features on the Seahorse 52 not ordinarily found on other boats. For example there’s a full stand up workbench and engine room large enough to house twin engines in a 52-foot boat! An optional flybridge is available.

Why settle for good, when you can have great?
