About the Gulf 27 Sailboat

Built by Capital Yachts beginning in 1970, this 27-footer represents classic American coastal cruising design from sailing's golden era. With her traditional masthead sloop rig and fin keel configuration paired with a spade rudder, the Gulf 27 offers responsive handling characteristics that appeal to both novice and experienced sailors. The boat's substantial 6,900-pound displacement and generous 2,750 pounds of ballast create impressive stability for coastal cruising and light offshore work. Her moderate beam of 9.33 feet provides comfortable interior space while maintaining seaworthy proportions. The fiberglass construction ensures durability and relatively low maintenance compared to wooden contemporaries of the era. Performance-wise, the Gulf 27 strikes a pleasant balance between comfort and sailing ability. Her sail area to displacement ratio of 15.81 indicates moderate power that won't overwhelm less experienced crews, while still providing satisfying performance in varied wind conditions. The comfort ratio of 22.78 suggests she'll handle moderate sea conditions well without excessive motion. This design works particularly well for weekend coastal cruising, sailing instruction, and as an entry-level cruiser for those seeking to explore protected waters and nearby coastal areas. The hull's proven sea-kindly characteristics have earned respect among sailors who appreciate traditional sailing qualities over pure speed.
