Owners choose the GRAND MARINER 23fromHARRISas a luxury day boat for family cruising and entertaining, and many specifically call out how well the layout works for kids, grandkids, and even dogs. It also shows up in lake rental and party-boat fleets, which reflects its popularity for social day use rather than overnighting.
On-water behavior earns consistently positive notes: with a Mercury Verado 250, independent testing reported about 46.1 mph at the top end, 0–20 mph in 3.8 seconds, and an easy cruising band roughly in the low‑ to mid‑30s up into the 40s depending on RPM. Reviewers and buyers often describe a firm, V‑hull‑like feel in turns with a soft, dry ride, and many owners opt for 250–300+ HP packages to support towing and watersports.
On board, the seating is spacious with thick foam and upscale finishes, and recent builds commonly feature JL Audio, Simrad screens, CZone integration, entertainment centers, plentiful storage, and modern charging (USB/USB‑C and wireless) that suits full days on the water. Routine Mercury outboard service is straightforward, though rigging runs behind the engine well can feel cramped, and forum reports on older boats mention items like steering‑cable binding, occasional transom sag on aged or high‑horsepower hulls, and small deck voids/spider cracks or minor leaks over many seasons.
