Character

Where this design lands on the numbers a shopper trusts — read straight from her own ratios.

LivelySea-kindly

Her light displacement on a moderate beam gives 13 — a quick, lively motion that feels every wave.

Comfort ratio 13
CoastalBluewater

2.30 — right around the 2.0 line, the edge between coastal and offshore.

Capsize screening 2.30
LightHeavy

94 — light for her waterline, so she is easily driven and quick to accelerate.

Displacement / length 94
EasygoingPowered-up

31.0 — a lot of sail for her weight; powered-up and eager, a real performer.

Sail area / displacement 31.0
TenderStiff

39% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 39%

Light and lively — happiest day-sailing and coastal-hopping in settled weather.

What the fleet has seen

The 1d 35, as the fleet has seen it

Derived from the videos the fleet has analysed of this model. ▶ marks open the moment aboard.

The 1d 35 is a 10.7-meter fractional sloop designed by Nelson Marek and built by Carroll Marine Ltd. between 1998 and 2001. This racing sailboat features a fin with bulb and spade rudder hull, a carbon mast with twin swept-back spreaders, and a hydraulically adjustable forestay for rig tension control. It displaces 2971 kg and has a 2.3-meter draft. The 1d 35 was originally delivered for one-design racing and has an IRC rating. Aboard *Quantum Sails*, sailors used a smartphone camera to digitize sail shape data, including draft depth, draft position, entry angle, and exit angle, correlating it with rig settings like jib lead, halyard tension, and sheet trim to optimize performance.1:00 The *Berthon International* channel toured a 35-foot Spirit of Joyride, a 1990s sport boat that now functions as a Spirit of Tradition racer, incorporating a wooden veneered transom, a varnished deckhouse, a new Lombardini inboard engine, and a carbon bowsprit.1:16
