Character

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

TrailerableBeam 2.16 m — inside the 2.55 m no-permit tow width across most of Europe, and the 2.59 m US and Canadian limit. About 476 kg of hull, so roughly 1,100 kg on a trailer: check that against your own towing rating.Ramp-launchableAbout 476 kg of hull, with a keel that raises or a draught shallow enough to float off a trailer — she can go back on the trailer at the ramp, not only into the water.Shoal draughtDraws 0.41 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 8 — a quick, lively motion that feels every wave.

Comfort ratio 8

CoastalBluewater

At 2.79 she sits above the 2.0 line — beamy for her weight, and happiest coastal.

Capsize screening 2.79

LightHeavy

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

Displacement / length 146

EasygoingPowered-up

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

Sail area / displacement 25.8

TenderStiff

19% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 19%

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

What the fleet has seen

The Sandpiper 15, as the fleet has seen it

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

The Sandpiper 15 is a 4.7-meter gaff-headed cat-rigged sailboat with a centerboard trunk, designed by Breck Marshall and built by Marshall Marine Corporation since 1972. It has a 2.2-meter beam, a 1.1-meter draft, and displaces 476 kg. Aboard *Atom Voyager*, a Sandpiper 32 schooner underwent a comprehensive refit, addressing structural rot, ballast failure, and system modernization. The refit included removing 1,100 pounds of corroded steel ballast plates and replacing them with lead bricks, rebuilding the cabin sole, and modifying the interior for a new 48-volt electric propulsion system.7:18 Structural repairs involved replacing water-damaged bulkheads and a rotted plywood pop-top core with Divinycell foam.13:00 The original integral waste tank was replaced with a bucket toilet system, and a new 37-gallon integral water tank was constructed.10:59 The schooner’s pop-top was shortened, and the electrical system was overhauled, including a 1000-watt inverter and a portable gas generator.19:22
