Additional Information

This one is Bristol. The owner has spared no expense in the seven years he has owned Seafari Blue. A recent move and lack of available moorage is forcing the owner to downsize after extensive upgrades. His loss is your gain!

This is a 58’ Offshore Pilothouse which is essentially the same yacht as the 62’ Offshore—the difference is the molded swim platform on the 62, they are otherwise the same yacht from the transom forward.

All Offshore yachts are known for their stable ride and solid construction; this one is no different. She is powered by Electronically controlled Detroit Diesels, providing the ultimate in reliability and has stabilizers to ensure a smooth ride even at hull speed in beam seas.

She is extremely easy to dock with Hydraulic Bow and Stern Thrusters, as well as her cockpit control station AND she is equipped with a Yacht Controller for wireless control of her engines and thrusters.

This is an immaculate Offshore 58 that can be purchased for a fraction of the cost of new.  She has been meticulously cared for by an owner with an open checkbook who wants things to just “work” and values reliability/ease of use over cutting corners and missing out on days of vacation time. He has owned her since 2016 and has upgraded and replaced a large portion of the systems/mechanics on board.

She cruises comfortably at 8.3 knots @ 1100RPM using only ~3gal/h per engine, or you can push her all the way up to 18.8 knots at max speed.  She is comfortable and capable at any speed with almost no bow-rise.

You can probably find a lower priced 58’ Offshore, if you wait around long enough, but you will wind up spending more to upgrade/repair everything that has already been taken care of on this one!

She is located in Seattle and can stay in her current slip for a few months if needed after closing.  Come take a tour today, if you are in the market for an Offshore you will quickly realize what a value she is.

The listing broker has piloted her extensively and knows this vessel well, please reach out with any questions by phone, text or email.

Manufacturer Provided Description

The Offshore 58 Pilothouse features a solid hand-laminated fiberglass hull with epoxy barrier coat, and hand-laminated fiberglass deck and superstructure. All Offshore yachts feature well thought-out details such as covered walkaround decks for maximum safety and comfort as well as window frames, doors, and hatches made of gelcoated fiberglass so they can’t corrode like aluminum or rot like wood. Offshore hull design features a generous beam and finely veed and deep forefoot that gradually tapers to a 12-degree deadrise at the transom. This design produces a hull that is quick to get on plane and knifes cleanly through waves and chop throughout the speed range.
