Character

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

LivelySea-kindly

Her moderate displacement on a narrow beam gives 29 — a moderate, middle-of-the-road motion.

Comfort ratio 29
CoastalBluewater

1.75 — just under the 2.0 offshore line; her beam is modest for her weight.

Capsize screening 1.75
LightHeavy

257 — moderately heavy for her waterline, a balanced cruising weight.

Displacement / length 257
EasygoingPowered-up

14.6 — modest power for her weight; easygoing rather than lively, and happier with a breeze.

Sail area / displacement 14.6
TenderStiff

45% of her weight is ballast — stiff, standing up well to her sails.

Ballast 45%

Built heavy and sea-kindly — a boat made to cross oceans and forgive a rough night.

What the fleet has seen

The Hallberg-Rassy Rasmus 35, as the fleet has seen it

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

The Hallberg-Rassy Rasmus 35 is a 10.5-meter masthead sloop designed by Olle Enderlein and built by Hallberg-Rassy from 1967 to 1978, known for its long keel and offshore liveaboard suitability.1:33 The first two boats had mahogany hulls, while subsequent models were GRP. Aboard *Santana*, a 1978 Hallberg-Rassy Rasmus 35, the long keel provides directional stability and structural protection, and its 1.3-meter draft allows access to shallow anchorages.1:33 The deep center cockpit offers protection from spray and wind, and a 45% ballast-to-displacement ratio contributes to stability.20:26 The vessel displaces 5488 kg, with 2.5 tons of ballast, and has a sail area-to-displacement ratio of 15.1:52 Its 39-horsepower Volvo Penta D2-40 engine, installed in 2012, provides propulsion and hot water.12:05 Electrical systems include 300 amp-hours of AGM batteries, 400 watts of solar, and a 2-kilowatt inverter.11:08 The boat carries 430 liters of water and 270 liters of diesel. The original thick teak deck is screwed into a closed-cell foam core.6:40 The small rudder, a consequence of the shallow draft, makes low-speed maneuvering difficult.7:32 The interior, with a side-galley and small salon, is considered cramped for two people and two dogs.5:34
