FOST Obsession 860 - HONDA BF250

If you asked me to describe the Obsession 860 of Fost Rib Boats shipyard in a few words, I would say without hesitation that it is a rigid inflatable boat (RIB) with a purely offshore character, primarily designed to travel smoothly in rough weather conditions, perfectly adapted to the demanding seas of the Aegean.
Its relatively long and narrow hull, with an entry angle of 62 degrees and a deadrise at the transom reaching 26.5 degrees, allows it to cut through waves like "butter" and enter the water smoothly, fully absorbing shocks so that they never reach the passengers.

Despite its narrow bow, the sundeck can comfortably accommodate two adults, featuring an overall length of 2 meters and a maximum width of 1.20 meters in the feet area. Below, there are two independent storage compartments capable of holding all the necessary safety equipment and plenty of luggage.

Weighing 287 kg and featuring a gear ratio of 2.00:1, Honda's BF 250hp engine incorporates a range of technological features designed to deliver high power while maintaining fuel efficiency. Oxygen sensors enable the Lean Burn system, which optimizes the air-fuel mixture through computer-controlled fuel injection, ensuring fuel savings at low loads. Meanwhile, the Boosted Low-Speed Torque (BLAST) technology advances ignition timing when the throttle is rapidly opened, enhancing power output.
BLAST is Honda’s unique air-fuel ratio and ignition timing technology, developed to improve torque during initial acceleration, reducing the time required to reach the planning mode.

Furthermore, high torque remains optimal across both low and high rpm ranges, thanks to the electronic Variable Valve Timing and Lift Electronic Control (VTEC) system.
VTEC is an exclusive Honda technology that utilizes variable valve timing and lift control mechanisms to enhance intake performance by adjusting valve opening and timing as engine speed increases. By delivering high torque across the entire rpm range—ensuring strong acceleration at low speeds and steady acceleration through to high speeds —VTEC contributes to improved fuel efficiency.
