Seamaster Sailer 23 Buyer's Guide
The Seamaster Sailer 23 is a Laurent Giles-designed 23-foot cruiser built by Seamaster Ltd. between 1968 and 1975, and she remains a recognizable name on the secondhand market for sailors wanting a small, solid fiberglass boat with real keel options. Shopping one means weighing bilge-keel versus lifting-keel versions and checking the age of a 1970s fiberglass hull and rig.
Layouts on the Used Market
Used Sailer 23s appear with either a bilge keel or a lifting-keel centreboard variant; the bilge keel lets the boat sit upright on a beach or drying mooring, while the lifting keel ranges from 2 feet 6 inches up to 5 feet 6 inches down for deeper-water sailing. The standard rig is a masthead sloop with a 110 sq ft main and 120 sq ft No. 1 staysail, and the boat's above-average headroom for its length makes the compact interior more livable than many peers. Reviewers once compared her accommodation directly with the Laurent Giles Pageant at a lower price, a useful benchmark when inspecting several similar boats.
Equipment and Common Upgrades
On the used market, a short-handed setup is commonly fitted, meaning simplified sheet and halyard leading for single or pair crew, and a chartplotter is also commonly fitted for navigation. Beyond those, buyers should expect varied owner-installed gear rather than a standard inventory, and the original engine could be any of several 5–10 hp petrol or diesel units on shaft drive, so confirm which is installed.
What to Inspect
A standard age-related survey of the fiberglass hull and deck is the practical step. Where a lifting-keel example is offered, the centreboard trunk and pivot should be examined for wear, and bilge-keel boats deserve a look at the twin-keel bonds.
Availability and Buyer's Takeaway
These boats are typically found in the United Kingdom and Ireland. For a shopper, the checklist is brief: confirm keel type and its mechanism, verify engine make and shaft-drive condition, check for a commonly fitted chartplotter and short-handed rigging, and survey the fiberglass as you would any 1970s hull.
- Decide bilge keel vs lifting keel for your cruising grounds
- Verify engine installation and running state
- Inspect centreboard or twin-keel structure as applicable
- Expect to add or update navigation and sail-handling gear
