For a few years of use, it carries the kind of light, expected cosmetic wear that reassures buyers it has been enjoyed responsibly rather than neglected. The overall condition presents with the confidence you want in a late-model Whaler—clean surfaces, strong systems, and nothing to hide in terms of upkeep or history. It’s a turn-key opportunity for someone who wants big-water capability without the uncertainty that often comes with older offshore boats. The 380 Realm is built for versatile days on the water—cruising with family, entertaining friends, or running out to deeper fishing grounds when adventure calls. The layout gives you comfort at the sandbar, protection when the weather shifts, and plenty of room to unwind after a long run. It strikes that sweet spot between luxury and practical usability, making it easy to picture weekend escapes or long summer days spent hopping from harbor to harbor. Located at The Boat House Door County, it’s already sitting in the heart of some of the Midwest’s most scenic cruising water. Shoppers who know Lake Michigan and the Door Peninsula understand how valuable a capable, confident hull like this truly is. Reach out to schedule a viewing—quality Whalers in this condition don’t stay available for long.Additional FeaturesQUAD MERCURY Joystick Plt 400 CXXL VeradoMassive cockpit with self-bailing sole and abundant storageRod holders on gunnels and transom for fishingWalkthrough transom door and integrated swim platform with telescoping ladderPrep center with stainless sink, electric grill, and Corian countertop.Refrigeration under prep station.Insulated fishboxes and refrigerated under-seat cooler(s).Extensive drink holders throughout bow, helm, and cockpit areasLarge integrated hardtop with LED lighting and railsSpacious helm with room for multiple large displays and premium electronicsWindshield with walk-through lower door for easier bow accessDual USB and 12 V charging points at helmEnclosed cabin with opposing convertible seating that forms a berth.Enclosed head compartment with VacuFlush toilet, shower, and storage.Galley amenities including stainless fridge, microwave, Corian countertops, and sink.Hardwood cabin sole and quality cabin finishes (teak cabinetry).LED interior lighting with dimmer switches.24″ HDTV (in some configurations)USB charging ports.Skylight with shade and opening portholes for ventilation.
