Cornish Crabbers Shrimper 21 Buyer's Guide
The Cornish Shrimper 21 on the used market is the slightly larger, updated sister to the very popular Shrimper 19, built to order so no two boats need look alike below or on deck. Because every example was specified by its original owner, a buyer is really shopping a small fleet of one-offs sharing the same hull, rig philosophy, and shallow-draught keel. Knowing which options were ticked matters more than chasing a particular model year.
Layouts on the Used Market
Most boats carry the standard gaff rig, though some were delivered in the Adventure range with a taller Bermudan rig in place of the gaff. Below decks you should expect two settee/quarter berths, a forecabin with a choice of chemical or sea toilet under the berth head, and a table that doubles as galley worktop. The cockpit is larger than the 19’s and laid out with single-level seating. Because layouts were built to owner requirements, some will show teak inlays on the cockpit seats while others remain plain; stowage around the galley varies with the chosen option package.
Equipment and Common Upgrades
Autopilots are commonly fitted, a useful addition given the boat’s easy-sailing, low-load rig. Less often seen but present on some boats are AIS and a chartplotter as owner upgrades, worth confirming if you plan sheltered-water navigation beyond familiar estuaries. The standard auxiliary was a Yanmar 1GM diesel inboard with cockpit-led controls, though earlier or lighter-spec boats may show an outboard in a stern well; electric inboard options existed as an emerging choice and turn up occasionally on river and broads-based examples.
What to Inspect
The rudder is transom hung with a stainless steel lifting drop plate, and that drop plate together with its pivot is a high-wear assembly worth checking for corrosion or free play, as boats.com details anchor. The lifting centreboard case should not intrude unduly on leg room when down, so confirm the keel lifts and drops smoothly and that the case is not distorted. Where an inboard diesel is fitted, verify the cockpit controls operate cleanly and the engine bay is dry.
Availability and Buyer’s Takeaway
These boats turn up most often in the United Kingdom and Germany. When viewing, work through this short list:
- Confirm rig type: gaff standard, Bermudan Adventure if specified
- Check drop-plate rudder and pivot for wear or corrosion
- Verify lifting centreboard operation and case condition
- Note auxiliary fitted: inboard diesel, outboard well, or electric
- Confirm autopilot present; AIS or chartplotter if navigation matters
- Match accommodation option to your toilet and berth needs
