The Pandora Mk I is a small, slimhulled yacht drawn from E. G. Van de Stadt's TrotterPandora lineage and built by Rydgeway Marine of Lowestoft, Suffolk after the firm acquired the moulds from Grimsby Plastics in 1970. At just under 22 feet overall, she occupies a deliberate middle ground between racingoriented 22foot dayboats and accommodationled cruisers of the same length, and she does so with a firstclass design pedigree behind her.

Pandora Mk I Buyer's Guide

Shopping the used market for a Pandora Mk I means taking home a 21-foot-10-inch Van de Stadt cruiser that Rydgeway Marine produced from 1970 after acquiring the moulds, with a reputation for standing the test of time. She was conceived as an inexpensive day yacht and later marketed as a quick, easily handled cruiser, and she remains a popular boat on the used market thanks to that longevity.

Layouts on the Used Market

The Mk I keeps an open-plan cabin with four berths and a molded GRP galley unit containing a sink and gimballed cooker. Headroom runs about four feet eight inches, and the cockpit stretches past seven feet to seat three crew. Rydgeway offered the same deck in several hull forms — fin keel, twin keels, or a drop-plate centerboard — so a buyer chooses between a 3-foot-9-inch fin, a 3-foot twin, or a 2-foot-3-inch triple draft rather than between interior plans. The 2-4 hp outboard engine is standard, mounted for simplicity rather than enclosed propulsion.

Equipment and Common Upgrades

Most Mk Is will show the original masthead-sloop rig with a 92 sq ft main and 160 sq ft genoa, and the trailerability owners prize means a road base and winch are consequential upgrades. Given the outboard power, a modern auxiliary bracket and fuel tank are the buyer-relevant energy items; canvas such as a spray hood and sail cover protects the open cockpit and aged deck. Navigation stays simple on a 22-footer, but a tiller pilot and basic instruments are the upgrades that matter more than comfort trims.

What to Inspect

The one documented wear point is the keel attachment: owner reports note that keel bolts and bedding can rust and wear anchor, so examine the bolt heads, surrounding laminate, and any staining at the hull-keel joint closely. Aside from that, she shows no tendency toward repair frequency above the norm for comparable small cruisers, and the design and build qualities have stood the test of time.

Availability and Buyer's Takeaway

The Pandora association is based in Abersoch, Wales and actively races Pandora yachts, supporting a live class. When viewing a Mk I, check the keel bolts and bedding for rust, confirm the rig and outboard match the 2-4 hp spec, verify the draft of the keel form you want, and inspect the open-plan cabin and seven-foot cockpit for structural soundness. A sound example delivers seaworthy, fun sailing in a trailered, two-person package.
