Reviews
Everyone at Harbor Marina is incredibly friendly and helpful. A great place to be.
Friendly staff greeted us on arrival and helped with lines. It's a small marina with floating docks that were safe but feeling their age. Limited amenities (no pool) but nice, clean & modern bathrooms & showers.
Rick and team were great. Super accommodating with last minute requests, twice. Never said no, even after hours support. Very nice dock hands and restaurant is great too.
Not a good place for large boats. Plastic wobbly floating docks (!) with no real cleats, not suitable for a 50 foot boat. Tied up at 7pm, No marina staff on hand, no slip assignment and no off hours contact info at marina office door, etc. frustrating after a long day cruising. Staff friendly during day.
