Corribee Mk I Buyer's Guide
Shopping the used market for a Corribee Mk I means looking at a 20 ft 3 in Robert Tucker design built by Mallon Boats from 1963, a fractional-sloop centerboarder whose slender hull and modest 1,120 lb weight backed by 416 lb of lead made her a documented offshore candidate. She is a proper little yacht in the original sense, but the same narrow beam that earned her sea-keeping praise also makes the below-decks space tight by any standard.
Layouts on the Used Market
The Mk I’s defining trait is the Tucker hull’s narrow beam, which restricts the space below decks. Buyers should expect the original compact arrangement: four berths, a galley, and a chart table with a chemical toilet beneath it. There is no alternative factory layout in the record, so any boat presented as a Mk I should match that footprint, and a widened or reconfigured interior is an owner modification rather than a standard plan.
Equipment and Common Upgrades
On the used market, solar, a dodger, an autopilot, and a chartplotter are commonly fitted to these boats. For a buyer, that cluster means the basic energy and helm-relief needs are often already addressed: solar keeps the autopilot and instruments fed at anchor, the dodger makes the cockpit usable in chop, and the chartplotter removes the need for paper navigation on short passages. Beyond those, expect little beyond the original chemical-toilet specification below.
What to Inspect
The constraints on the Mk I are geometric. The narrow hull restricts the available space below decks, so verify that the four-berth, galley and chart-table layout is intact and that the chemical toilet is present under the chart table restricts the available space below decks. Confirm the centerboard and its trunk operate, since the 3 ft 2 in draft depends on it, and check the hull for the slender Tucker profile and long overhangs that identify a true Mk I. The cramped volume is inherent and cannot be “fixed” by a seller.
Availability and Buyer's Takeaway
The Corribee Mk I is typically found in the United Kingdom. For a buyer, the takeaway is simple:
- Confirm the narrow-hull four-berth interior with chemical toilet under chart table
- Verify centerboard operation and trunk condition
- Check for commonly fitted solar, dodger, autopilot, chartplotter
- Expect cramped below-decks space as designed, not as damage
