Built during a brief but productive four-year run from 1977 to 1980, this compact cruiser represents a collaboration between renowned designers Edwin Monk and Robert Perry for Sun Yachts. With only 155 hulls produced, the Sun 27 has earned recognition as a well-balanced coastal cruiser that punches above its weight class. The design showcases classic late-1970s thinking with its fin keel and spade rudder configuration, delivering responsive handling and respectable sailing performance. The boat's moderate displacement of 6,200 pounds, combined with 2,300 pounds of ballast, creates a stable platform that inspires confidence in a variety of conditions. Her 340 square feet of sail area provides adequate power for coastal cruising and weekend adventures. The Sun 27's comfortable motion at sea stems from her sensible proportions and the designers' attention to seaworthiness. The hull's 22.50-foot waterline generates a theoretical hull speed of 6.36 knots, making her capable of respectable passage times under sail. Her masthead sloop rig keeps sail handling straightforward, while the fiberglass construction ensures durability and low maintenance. This boat suits sailors seeking a capable coastal cruiser for weekend getaways, small crew adventures, or as an entry point into serious sailing without overwhelming complexity.
