FPB 115 Basic Specifications

FPB 115 Outboard profile bottom rev

The FPB 115 is the latest in the iconic FPB range of globe trotting motor yachts. Following in the footsteps of the FPB 64 and 83, the 115 offers efficient long distant cruising with the ability to endure adverse weather in comfort and safety.  She has a 5000+ nautical mile range at her cruising speed of 12 knots. Given the proven heavy weather performance of the smaller FPBs, the 115 could arguably be called the finest extreme weather yacht ever conceived.

With just five foot draft and the ability to dry out in tidal estuaries, the FPB 115 can explore areas typically unavailable to larger yachts. Add in a structure designed to twice the Lloyds Special Service Rule, with 12mm (15/32″) bottom plate, and high latitude environments become more inviting.

The FPB 115 is based on a standardized package of structure and systems, with wide latitude of interior layouts.  Plans are available for owners who prefer to cruise without crew, for commercial operators, and fully crewed versions.

All versions feature six electric self-tailing deck winches for handling dock lines and shorefasts in high latitudes. Twin engines and oversized rudders give precise control for maneuvering in tight quarters. Add in 360 degree views from the pilot house and flying bridge, with good sightlines in close, and it becomes possible to cruise with minimal (or no) crew if you are so inclined.

A pair of 300HP John Deere diesels will deliver a top speed of 14.5 knots at half load. The FPB 115 features the generator independent systems for which Dashew Offshore are so well known and can go for extended periods at anchor without running the genset.

    I have been following your exploits and designs for years. I am the captain of a 70′ Chuck Paine designed Trawler and heading up the east coast headed towards the canadian maritimes. I would like to catch up to you somewhere and see Wind Horse. What is your tentative schedule.

    Hi Kevin:
    We are in Beaufort, NC. No real schedule other than if we have a fair breeze we will head as far north as it takes us, the eventual goal being Maine.

    I find the shift from 112 to 115 feet interesting, correct me if I wrong but my understanding is that 35 metres (114.8 feet) is the cut off for requiring a pilot aboard to enter many ports around the world. Anyone who actualy does this rather than dreams of doing it able to confirm or deny that because requiring the services of a pilot at every port entry is going to get both expensive and time consuming.

    Hi Rob:
    Pilot requirements vary from all sizes (Puget Sound, Washington), to 20 or 24 meters, some are 35, and more 50 meters. The measured length, probably 34M for the FPB 115, is what counts.

  5. Paul Says:

    I`m sure its the question that many would like to ask; have you run any costing yet or do you have an approx. selling price.

  6. Steve Dashew Says:

    Hi Paul:
    Working on pricing now. Contact ToddR@SetSail.com for details.

    We’ll be in the Chesapeak until July 10th, are you planning to visit anywhere in the Chesapeak during that time period?

    Hi Kevin:
    We might be in Norfolk on the way north, but probably not until Septmber in the Chesapeake.
