About the 1D 35
ONE-DESIGN 35. Carbon mast with twin, swept-back spreaders. As originally delivered for one-design racing, the 1D 35 has no backstay(s). (at hounds or topmast). Rig tension is controlled under way with an hydraulically adjustable fore stay. Dimensions shown here from a sample IRC cert.
The 1D 35 is a fractional sloop designed by Nelson/Marek and built by Carroll Marine Ltd.(USA) between 1998 and 2001, with a total production of 48 hulls. This limited production run suggests a niche market appeal, often associated with custom or semi-custom builds from that era.
- Best for:
- This vessel is best suited for coastal cruisers and performance-oriented sailors who appreciate a fractional rig and moderate displacement, given its D/L ratio of 93.55 and SA/D ratio of 36.77.
- Bluewater capability:
- With a displacement of 6550.0 lb and a capsize ratio of 2.3, the 1D 35 exhibits moderate offshore capability, though its relatively light displacement and fin keel suggest it is more optimized for coastal and nearshore cruising than heavy bluewater passage-making.
- Comparables:
- Comparable boats include the Nauticat 35 and the Tartan 35, as they share similar beam dimensions (10.75 ft) and fractional sloop rigs from the late 1990s, offering a balance of performance and comfort.
