Design and Construction
The Sandpiper combines a fiberglass hull, shoal draft, and a spacious cockpit suited to thin-water gunkholing. Marshall Marine builds its catboats with solid fiberglass hulls and side decks, and an integral centerboard trunk. Closed-cell foam reinforces the foredecks, cabin tops, and transoms. A Sandpiper hull may wear pink gelcoat.
The yard estimates the worldwide Marshall fleet at around 1,400 boats, including some in Germany, Denmark, Antigua, and Chile. One made an almost 1,500-mile round trip from Massachusetts to the Newfoundland iceberg fields.
Rig and Handling
Owners who stepped down from 20-ton keelboats describe the Sandpiper as quick but temperamental. Flattening the sail helps the boat point higher, but it loses speed and position if the crew looks away for even a few seconds. Owners report that it needs constant trim or becomes fussy.
The builder claims a comfortable, stable ride for sailors of all ages and abilities. Its shoal draft also lets it reach grounds that deeper boats cannot.
Cockpit and Use
There’s no cabin. Instead, the open, roomy cockpit and shoal draft define the boat. The maker cites versatility and cruising range, a claim borne out by the Newfoundland voyage.
Known Issues
A Sandpiper can capsize in a flash if its boom tangles with another boat’s sheets. Its single large sail, set on a short mast, sweeps through a wide arc and leaves little margin in crowds. The boat’s need for constant sail attention adds to the workload.
Refits and Ownership
Steady factory output aids support. The boat’s simplicity leaves little beyond sail and rigging care.
The Verdict
The Sandpiper is a tiny, demanding catboat that needs active handling and vigilance around other boats.
