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 25 — a moderate, middle-of-the-road motion.

Comfort ratio 25
CoastalBluewater

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

Capsize screening 1.96
LightHeavy

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

Displacement / length 160
EasygoingPowered-up

20.4 — plenty of sail for her weight; lively and quick to respond.

Sail area / displacement 20.4
TenderStiff

43% of her weight is ballast — stiff, standing up well to her sails.

Ballast 43%

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

What broke, what changed

Gear aboard, as the crews told it

Moments from individual boats of this model that the fleet has filmed — one crew, one piece of kit, one day on the water. Not a review of the class, and not a count of anything.

Each line is one crew's account of their own boat. Another X Yachts X-43 may be fitted out entirely differently.
