Design: History & Description

From Wavetrain.net:

American shipwright and boat designer Thomas Colvin, who has long championed both metal construction and junk rigs on cruising sailboats, has designed about 300 small ships and boats over the course of a career that has now spanned about 70 years. He designed the original Gazelle for himself and his family to cruise aboard way back in 1967. The Gazelle has since proven to be both his most successful and perhaps most interesting creation, with over 700 sisterships launched to date.

The first Gazelle was conceived as a no-frills light-displacement boat that could function both as a shoal-draft coastal cruiser on Chesapeake Bay, where Colvin was based at the time, and as a bluewater cruiser. She was built of 10-gauge Corten steel. Her most distinctive feature was her schooner rig, which consisted of two Chinese junk sails mounted on lightly stayed aluminum masts with a Western-style triangular jib out front flying from a long bowsprit. She also carried a triangular “fisherman” sail between her masts or sometimes flew a loose-luffed reaching staysail from her main masthead.

By all accounts the first Gazelle sailed well, as is reflected in her performance ratios. She balanced well on all points of sail, her helm required little attention, except when running dead downwind, and she was reasonably fast. Colvin reported hitting speeds of around 9 knots sailing his boat. Thanks to her narrow beam, shoal draft, and generous sail plan, she also needed reefing early, which is easy to do on any junk-rigged vessel.

The interior lay-out is similar to those seen on modern center-cockpit boats, except there is no cockpit. Instead the helmsman is stationed on a flush-decked area between the main and aft cabins, directly abaft the mainmast and directly over the engine or cargo area.

The main cabin connects to the aft cabin below deck via the engine or cargo area, which has only stooping headroom. The main cabin does have full standing headroom and the forepeak has a narrow V-berth bisected by the keel-stepped foremast, which precludes installing a filler section to make the berth a double.

Design Modifications for Gaia

Gaia’s rig was designed by Sunbird of England (Allan Boswell) and is self standing (stay and shrouded except for a forestay for the genoa and temporary backstays.

Gaia has a cockpit and a much loved light weight pilot house. 

Gaia has a forward facing steering wheel activating a torgue tube steering system designed by Whitlock of England.

Gaia’s interior is light and airy with 14 opening ports and differs markedly for Tom’s concept. She is the opposite of ‘no frills’.
