LeComte Alc 40 Buyer's Guide
Shopping the used LeComte Alc 40 means looking at a Dutch-built Sparkman & Stephens design from the early seventies, also badged as the Le Comte 40. She is a 39-foot fiberglass masthead sloop with a lead fin keel and a narrow hull that has aged into a credible cruiser-racer for the right buyer.
Layouts on the Used Market
The Alc 40 was offered with different keel alternatives, and the lead fin keel appears on many survivors. Two draft bands exist: a shallow fin at roughly 4.6–4.9 feet and a deeper fin near 5.7–6.0 feet, both load-dependent. A buyer should treat the quoted draft as a light-ship figure, because each added 1,227 pounds of cruising gear lowers her by one inch immersion of one inch per 1,227 pounds, so any added equipment pushes the waterline down and eats into the marina-friendly shallow draft.
Equipment and Common Upgrades
In the Netherlands these boats commonly carry radar, autopilot, and chartplotter as factory or dealer-fitted navigation equipment. That trio covers offshore passage-making and short-handed steering without needing owner-added electronics. The engine option is an inboard Westerbeke 4-107 diesel at 37 horsepower, with Vire as the supplier.
What to Inspect
No structural or osmotic defects are known for this model. The one quantified check is draft behavior: because she immerses about 1,227 pounds per inch, measure freeboard at the bow and stern with the boat loaded as she will be cruised, and compare to a known-unloaded sister ship or the designer's lines. A hull sitting disproportionately deep for her visible gear suggests undocumented ballast additions or water ingress. Confirm which fin keel is fitted and that the lead foil shows no impact cracks at the hull joint.
Availability and Buyer's Takeaway
These boats are typically found in the Netherlands. Before committing, walk through this short list:
- Confirm the fin keel type and measure loaded draft against spec.
- Check freeboard for signs of excess immersion or unreported weight.
- Verify the Westerbeke 4-107 or Vire diesel runs clean.
- Test the radar, autopilot, and chartplotter at power-up.
- Inspect the lead keel-hull joint for impact damage.
