Inside / heated winter storage included! Don't miss this incredibly rare opportunity to own and enjoy this clean, freshwater, original-owner Mainship with only 144 hours on her twin Crusader 350's with EFI & FWC. We delivered her in 1999 and she was berthed here and winter stored in our heated storage since then. She has been professionally wheeled & waxed and maintained by our service departments. Other highlights include dual air & heat units, GPS / plotter, VHF, Tri-Data, newer bimini canvas with full enclosures, bridge cover, cockpit canopy, dripless shaft seals, and new batteries this season. The 31 Sedan Bridge features a large, uncluttered flybridge with plentiful seating and storage. Wide molded fiberglass steps replace the standard ladder, offering safety and comfort. A bridge walk-through to the foredeck along with oversize handrails add to the safety of this ultra-functional and comfortable Mainship. Please inquire for more details!
