A 20foot open daysailer designed by B.B. Crowninshield in 1915, the Dark Harbor 12 1/2 was built by Rice Brothers as a carvelplanked wooden hull carrying a gaffhead sloop rig on a fin keel. At 20 feet 2 inches overall with a 5foot 4inch beam and a 3foot 2inch draft, she displaces roughly 1,923 pounds and draws her character from a long lineage of small open boats meant for day sailing rather than cruising below.

Dark Harbor 12 1/2 Buyer's Guide

The Dark Harbor 12 1/2 on the used market is a 1915 B.B. Crowninshield design built by Rice Brothers as a 20-foot 2-inch open wooden daysailer, carvel-planked over steamed frames with a gaffhead sloop rig. She is a boat for the wooden-boat enthusiast rather than the casual weekend sailor, and any purchase decision turns on the condition of the hull and the honesty of the maintenance history.

Layouts on the Used Market

Every example is an open daysailer with no enclosed cabin, so the only layout question is cockpit and deck configuration. Original carvel-planked hulls over steamed frames are the norm, though some later boats use cold-molded or strip construction. A buyer should treat the open cockpit and flush foredeck as the defining layout and look for structural integrity rather than interior appointments.

Equipment and Common Upgrades

No equipment tiers or upgrade lists are carried for this model, so a buyer should evaluate each boat on its own rig and trailer. The gaffhead sloop rig with about 210 square feet of sail is the constant; anything beyond that is owner-fitted and should be judged on condition.

What to Inspect

The defining check on a carvel-planked hull over steamed frames is moisture discipline — a boat that has dried out will show opened seam lines and cracked caulking along the topsides carvel planked over steamed frames. Run a finger along the garboards and the sheer strake for softness, and look for dark staining at frame ends that signals rot. Where a seller offers a cold-molded or strip example, inspect glue lines for separation and listen for hollow delamination under light tapping. Because the four-sheet plan set is sparse and lofting is required, any repair work should be credited only to an experienced wooden-boat builder — ask who did the last plank or frame work and walk away from undocumented repairs suggested for experienced builders only as the plans info is sparse.

Availability and Buyer's Takeaway

The buyer’s task is simply to find a sound example and verify its structure.

  • Check plank seams for opened caulking
  • Probe frame ends for rot staining
  • Verify any cold-molded work with a builder reference
