Share Listing

  • This particular Silverton has been completely redone and customized, transforming a proven hull into a modern, turn‑key sport fisher. The fiberglass work is beautifully finished, showcasing top‑quality craftsmanship with a clean, professional look throughout. In 2013, the boat received twin 375‑hp Marine Power gas engines that deliver a comfortable 16.5‑knot cruise, giving it both reliability and strong performance.
    The redesigned interior is beamy and spacious, offering a fresh cabin layout that feels open, bright, and highly functional. An Air‑ride captain’s chair makes long runs smooth and comfortable, while two additional bunks tucked under the main cabin, in addition to V-berth cabin, provide excellent sleeping capacity. Updated Garmin electronics and dual VHF radios give the helm a modern navigation suite that’s ready for offshore or coastal cruising.
    Flybridge steering offers outstanding visibility, making this boat a pleasure to run in any conditions. The large head with a hot‑water shower adds comfort rarely found on vessels of this vintage. Every upgrade reflects thoughtful customization, making this Silverton a standout example of classic design elevated with modern features.
    Altogether, it’s a beautifully restored, well‑equipped sport fisher ready for serious adventure.
