About the Snapdragon 29 Sailboat

Introduced in 1971 by Thames Marine, this British-built cruiser represents a practical approach to coastal sailing with its distinctive twin keel configuration. The fiberglass construction and masthead sloop rig make the Snapdragon 29 an accessible choice for sailors seeking versatility in shallow waters and tidal areas. The twin keel design stands as this boat's defining characteristic, allowing it to dry out safely in harbors and explore shallow anchorages that would be off-limits to traditional deep-draft vessels. With a draft of just 3.25 feet and beam of 9.50 feet, she offers impressive stability while maintaining the ability to navigate challenging coastal waters. The substantial ballast of 3,000 pounds provides reassuring stability for her 7,500-pound displacement. Performance-wise, the Snapdragon 29 delivers respectable sailing characteristics with her 300 square feet of sail area driving a hull speed of 6.56 knots. The comfort ratio of 22.66 suggests a motion that favors stability over speed, while the capsize screening formula of 1.94 indicates good seaworthiness for coastal cruising. This design appeals particularly to sailors interested in exploring tidal waters, beach cruising, and coastal adventures where shallow draft capability opens up numerous anchoring possibilities unavailable to conventional keel boats.
