Character

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

TrailerableBeam 2.44 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 1,452 kg of hull, so roughly 2,050 kg on a trailer: check that against your own towing rating.
LivelySea-kindly

Her moderate displacement on a moderate beam gives 15 — a quick, lively motion that feels every wave.

Comfort ratio 15
CoastalBluewater

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

Capsize screening 2.17
LightHeavy

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

Displacement / length 193
EasygoingPowered-up

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

Sail area / displacement 18.2
TenderStiff

52% of her weight is ballast — very stiff, carrying full sail in a blow.

Ballast 52%

A balanced, easily-driven cruiser — comfortable and forgiving for coastal work.

Aboard *Life is Like Sailing*, the owner recalled his sailing origins in 1996 after seeing a yellow San JUAN 24, the same model and color as his first sailboat.9:45 For first-time sailboat buyers, the San JUAN 24 is considered a trailerable option that simplifies storage and insurance.5:16 When inspecting a San JUAN 24, buyers should check keel bolts for rust, the bilge floor for cracks, the deck for soft spots, and chain plates, bulkheads, and the transom for solid attachment.2:20
