1 D 35 Information, Review, Specs

The 1D 35 was in production from 1998 to 2001, with Carroll Marine constructing approximately 48 units of this focused racing machine. Nelson/Marek's design philosophy for the 1D 35 aimed to integrate features from both sport boats and offshore-oriented IMS (International Measurement System) yachts, resulting in a versatile platform suitable for various racing disciplines, including overnight races. The goal was to create a boat that stripped away complexities, emphasizing pure speed and responsive handling, while also establishing a strict one-design class to minimize rule-related complications.

Carroll Marine, known for its dedication to cutting-edge design and robust construction, utilized advanced techniques for the 1D 35. The hull was constructed using a post-cured wet preg method, employing bidirectional E-glass and epoxy resin, which was then vacuum-bagged and post-cured at 140 degrees. A balsa core was incorporated to ensure high shear strength, contributing to a hull that proved to be extremely stiff and durable after a season of racing. A defining characteristic of the 1D 35's rig is its carbon mast with twin, swept-back spreaders, and notably, the absence of a conventional standing backstay. Rig tension is controlled on the fly through an hydraulically adjustable forestay connected via a Vectran strop, providing precise tuning for optimal performance., 6, 11]

Sailing Performance and Handling

The 1D 35's performance ratios clearly indicate its purebred racing intentions. With a sail area to displacement ratio of approximately 30.9, and cited figures ranging up to 36.77, it boasts an exceptionally large sail plan relative to its weight, suggesting potent light-air performance and the ability to load up quickly. Its ballast to displacement ratio of about 0.385, coupled with a lightweight displacement of 6,550 lbs and a displacement to length ratio around 93.5, signifies a light yet stiff and stable hull capable of standing up to significant wind pressure., 12]

Anecdotal reports consistently praise the 1D 35's exhilarating handling and speed. It has been described as easy and fun to sail, capable of planing over flat water at speeds up to 18 knots in moderate breezes. The boat’s substantial spade rudder contributes to its excellent handling, allowing for precise control, even downwind. Tacking is quick and effortless, aided by the absence of a backstay that allows the large mainsail to flop over freely, and the relatively small 110% jibs are easily sheeted by hand. While powerful and easily driven, the boat performs best when crew weight is effectively leveraged on the rail, particularly in upwind conditions. The deck layout is highly optimized for racing, with most control lines led under the deck, providing a clutter-free and efficient workspace for the crew.

Accommodations and Layout

As a dedicated race boat, the 1D 35's interior is functional and lightweight, prioritizing sail storage and crew accommodation over extensive creature comforts. The maximum headroom is limited to 5.33 feet, meaning taller crew members will need to maneuver bent over., 5] The layout is typically open, designed to sleep four to six individuals with a combination of four fixed bunks and two removable pipe berths.

Amenities are minimal but sufficient for offshore racing. The interior includes a small sink located forward near the mast and an area for a portable burner or camping-type stove. A modest, albeit somewhat exposed, head is situated just forward of the main bulkhead on the starboard side. There is also counter space available forward, often utilized for spreading out charts, and a cool box that doubles as the bottom step of the companionway, providing a practical stowage solution. The interior finish is largely utilitarian, with structural panels and a molded deck lining. While aesthetics are secondary, the quality of the fiberglass work is evident in the unpainted ends of the boat, and the electrical systems are robust and well-installed for reliability in demanding conditions.

Owner's Perspectives

Owners frequently describe the 1D 35 as one of the best, fastest, and most enjoyable 35-foot boats available, praising its simplicity to sail and transport. The robust construction, particularly the stiff hull achieved through Carroll Marine's advanced building techniques, is a consistent point of appreciation, contributing to the boat's solid feel and durability. Its high-performance capabilities often attract serious and talented sailors, contributing to competitive and engaging one-design racing. The boat's design also allows for single-point hoisting with a 4-ton dry lift and trailering with a light truck, making it convenient for owners who prefer dry-sailing.
