  • Onboard the DETERMINATION Yacht

    The DETERMINATION yacht is ranked number 4,613 among the world’s largest yachts.

    In 2016 she was one of 355 yachts greater than 65' (19m) delivered by all yacht builders combined, and the 100th largest yacht built by the world-renowned superyacht builder Westport, based in United States.

    Motoryacht DETERMINATION has had one custom refit, in 2025. She also has the former name registered, TIRELESS, which suggests that the DETERMINATION yacht sold, changing ownership one or more previous times.

    Measuring in at a length of 111' 11" (34.1m) and boasting a beam of 23' 9" (7.24m), DETERMINATION's grandeur is matched only by her spaciousness. Her draft of 5' 6" (1.68m) allows for an interior volume of 228 GRT (gross registered tons) which contributes to her exceptional performance on the open ocean.

    Up to 8 guests can be accommodated on board the superyacht DETERMINATION in 4 staterooms. DETERMINATION also has accommodations for 4 crew members, including the yacht’s captain.

    Constructed with a GRP hull, and GRP superstructure, she offers ample exterior and interior space.

    Powered by two MTU main engines, each generating 1,491 horsepower, for a total combined output of 2,982 horsepower. Notably, the DETERMINATION yacht is one of 4,548 yachts greater than 65’(19m) with MTU engines.

  • Note to visitors and U.S. Customs & Border Protection

    Vessels not for sale or charter on this website are for informational purposes only. If offered, DETERMINATION may not be available to U.S. residents while in U.S. waters, or to EU residents while in EU waters, unless operating in a Foreign Trade Zone (FTZ) or under a boat show bond. Please consult your broker for details. DETERMINATION yacht owner, broker, or captain, use the form below to report any changes to the status, images, or information of this vessel. Prices are converted into the selected currency for comparison purposes only; check current exchange rates to verify. This website strives to provide accurate information, but makes no guarantees regarding the DETERMINATION condition or details. Media shown may not depict actual photos, or the most recent photos of DETERMINATION for charter, and may include images from before refits or modifications. Please contact your yacht broker for the most up-to-date information. Presented courtesy of YDIQ, if available, DETERMINATION may be centrally listed with another yacht brokerage and is offered through this broker/dealer for client convenience. It does not constitute a direct representation. Due to the dynamic nature of the yachting industry and the lack of a centralized global listing service for all charter yachts and yachts for sale, it is impossible to maintain a fully current view of the market. Yachts often change status, leave the market, are sold, or are renamed, making it challenging to confirm their availability for charter or sale at any time. While we utilize third-party services and make every effort to ensure accurate information, the appearance of a listing on this website should not replace official documentation provided by a yacht’s authorized representatives. The DETERMINATION for charter, if offered, may be sold, subject to price changes, or withdrawn from the market without notice.
