Sea Force IX has developed a standard boat based on design, sound engineering practices and a personal comfort level that classifies this vessel as fully founded and ready to perform. Sea Force IX reserves the right to make changes at any time to engineering, specifications, equipment, materials, and prices without prior notice. There are also no obligations to modify previously manufactured vessels prior to or after the effective date of sale.
The optional equipment list was developed to offer upgraded products or systems that are generally regarded as personal preference items. Option pricing applies only when included on the original order, prior to vessel going into production. Sea Force IX must approve any additional items prior to construction.
Speed and range predictions are based on 81.5 sea trials, data from 81.5 and 91.5 tank test results, computer projections, engineering and building experience. All speeds projected are targeted to Sea Force IX’s sea trial program specifications considering weight and conditions. Weight from personal gear, options (i.e.: bow-mounted personal watercraft and stabilizers) and conditions not under the control of Sea Force IX may affect the vessel’s speed.
Speed and range predictions available upon request. For additional details, see the General Specifications.
