About the 1D 35 Sailboat

Nelson and Marek's 1D 35 represents a focused approach to performance sailing, designed during the late 1990s when the sailing world was embracing more aggressive hull forms and lighter displacement concepts. Built by Carroll Marine between 1998 and 2001, this fractional sloop demonstrates classic modern racing yacht characteristics with its fin keel and bulb configuration paired with a spade rudder arrangement. With a displacement of just 6,550 pounds and generous sail area, the 1D 35 delivers impressive sailing performance particularly suited to coastal racing and spirited day sailing. The boat's low comfort ratio of 13.15 reflects its performance-oriented nature rather than cruising amenities, while the moderate capsize screening value of 2.3 suggests reasonable stability for experienced sailors. The deep 7.58-foot draft and substantial ballast-to-displacement ratio provide the power to carry sail effectively. Limited production of just 48 hulls makes the 1D 35 a relatively rare find on the used boat market. This scarcity, combined with the respected Nelson/Marek design pedigree, appeals to sailors seeking a distinctive performance boat that stands apart from more common production cruisers. The fiberglass construction ensures durability while maintaining the precise hull shapes critical to the design's sailing characteristics.
