Taking advantage of growing name recognition, Dolf formed a sales company, Adolf LeComte Company, Inc. in the United States and LeComte-Holland, N.V. opened a building yard in the town of Jutphaas, south of Utrecht in the Netherlands. Contracts with the yacht design firm of John Alden Co. resulted in the wood construction of 33' Malabar Senior sloops and 42' Nordfarer yawls, followed by the finishing of Halmatic-moulded 38' Challenger yawls.
In 1961, LeComte-Holland moved into fiberglass construction exclusively, starting with the Medalist 33 sloop, followed in 1962 with the North East 38 sloop/yawl. Quality construction was the norm, with solid-glass hulls, Airex-cored decks, yacht quality varnished interiors and attractive designs joined in a competitive hull and rig design. 1965 brought the flush-deck, teak-decked 52' Ocean Racer, the last of the Tripp designs with LeComte. In addition to constantly upgrading the yachts, in 1966 a complete redesign of hulls, rigs and interiors kept these designs current and popular.
In 1968, soon after opening a modern building facility in Vianen on the Lek River, (just south of Jutphaas) the Luders-designed Fastnet 45 sloop/yawl joined the LeComte family. 1970 brought the phasing out of the Medalist 33 in favor of the LeComte-designed ALC-35 sloop, and 1971 replaced the North East 38 with the ALC-40 sloop. 1973 brought the redesign of the Fastnet 45 as the ALC-46 sloop/ketch.
Retiring in 1994, Dolf LeComte closed LeComte-Holland and sold the Vianen property
to a non-marine industrial user. Meanwhile, the New Rochelle marina is home
to Glen Island Yacht Club with slips filled exclusively by sailboats summer
and winter, West Harbor Yacht Service providing a full-time crew with skills
in hauling, rigging, yacht quality carpentry, metalworking, engine service,
marine electrical and plumbing, and A. LeComte Company, specializing in the
resale of LeComte yachts and other sailing yachts.
