Westerly GK 29 Buyer's Guide
The Westerly GK 29 is a 1978–1981 British-built IOR half-tonner from Westerly Marine Construction Ltd, designed by Michael Pocock with Jack Laurent Giles. With 182 made, she is a recognizable name in the used small-racer market but not a high-volume class, so a careful viewing matters more than a quick comparison of listings.
Layouts on the Used Market
The GK 29 is a masthead-rigged fin-keel sloop with a transom-hung rudder and a solid fiberglass hull. Below she carries six berths with a galley and a toilet, and the beamy hull gives her more interior volume than most similar 29-footers, which is the main reason the berth count works for a small cruising crew rather than being a paper number.
Equipment and Common Upgrades
Boats on the market often carry a spinnaker or asymmetric spinnaker, an autopilot, a chartplotter, and a life raft. For a half-tonner these are the consequential additions: the spinnaker gear restores the downwind performance the IOR rule rewarded, while the autopilot and chartplotter turn a race-derived hull into a manageable short-handed cruiser. A life raft is the safety baseline a buyer should expect on any offshore-capable listing.
What to Inspect
The GK 29 has no model-specific fault lines in the review record, so a buyer's inspection centers on standard age checks for a 1978–1981 fiberglass hull. Confirm the iron ballast keel attachment and the transom-hung rudder stock, and verify the engine — either a 6 hp or 12 hp diesel — starts clean and shifts the shaft drive without excess play.
Availability and Buyer's Takeaway
These boats are typically found in the United Kingdom, Belgium, Ireland, and the Netherlands.
- Verify the keel-to-hull joint on the iron ballast fin
- Check the transom-hung rudder for stock wear
- Confirm the diesel engine and shaft drive operate smoothly
- Look for spinnaker or asymmetric gear and a life raft
