Character

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

TrailerableBeam 1.07 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 35 kg of hull, so roughly 650 kg on a trailer: check that against your own towing rating.Ramp-launchableAbout 35 kg of hull, with a keel that raises or a draft shallow enough to float off a trailer — she can go back on the trailer at the ramp, not only into the water.Shoal draftDraws 0.10 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
LivelySea-kindly

Her light displacement on a beamy beam gives 3 — a quick, lively motion that feels every wave.

Comfort ratio 3
CoastalBluewater

At 3.29 she sits above the 2.0 line — beamy for her weight, and happiest coastal.

Capsize screening 3.29
LightHeavy

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

Displacement / length 97

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

What the fleet has seen

The Optimist Dinghy (INT), as the fleet has seen it

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

The Optimist DINGHY (INT) is a 2.3-meter pram-hulled sailboat with a sprit/lug rig, designed by Clark Mills in 1947. It displaces 34 kg and is widely used as a youth trainer, built by numerous home and professional builders. Aboard *navegandoporelglobo*, a crew refurbished an Optimist dinghy by sanding and repainting it during a larger refit of their sailboat, Zen, for a transit from the Netherlands to Valencia, Spain.18:24
