Carl Alberg (1900-1986)
Carl A. Alberg was born in Gothenburg, Sweden in 1900 and is the designer of the Sea Sprite.

“The harbor was always filled with ships and boats of all kinds and when we weren’t sailing there, the family usually vacationed on an island off the coast where my father, brother and I used to race each other in small sailboats.” He took two years of sailboat design courses at Chalmers University of Technology in Gothenburg. In 1925, he moved to Lynn, Massachusetts, USA and worked as a rigger for General Dynamics in Quincy. He moved on to become a spar-maker at the Lawless boatyard in Neponsett. There, he met John Alden who hired him as a designer.

“I enjoyed working with Alden very much. He was a wonderful guy, pleasant, calm, never getting excited, and I learned quite a bit from working with him. His designs were conservative. He concentrated on seaworthiness, comfort and boats that would sail on their bottoms, and that’s pretty much what I’ve tried to do with my boats.” During World War Two, he interrupted his tenure at Alden to work for the Navy at the Charleston Naval Shipyard. After his return, he designed the U.S. One-Design. In 1946, he left Alden for good, starting his own firm. Another short period at the Charleston Shipyard during the Korean War led to a 10-year position with the Coast Guard as chief marine engineer/architect.

Toward the end of that period he met the Pearson cousins, who were kids just hanging around the boats. He asked them about building one of his designs in fiberglass, and, in 1959, both the Triton (28 feet, 675 built) and Pearson Yachts were born.

In 1961, a small group of Toronto sailors approached Kurt Hansen, then of Continental Yacht Sales, with an idea of a 30-foot fiberglass boat for class racing. Mr. Hansen contacted Carl Alberg late in that year.

The design was based on Carl’s design, the “Odyssey,” of which fifteen had been built in San Francisco in 1959. Intended for the heavy weather of the San Francisco Bay and the Pacific Ocean, the Odyssey had a heavy displacement and a 7/8ths rig. The original Alberg-30 drawings followed this design with 2000 pounds less displacement and 3 inches less draft. By mid-1962, the plans were complete and construction commenced.

Whitby Boat Works came into being. Kurt Hansen changed the ballast from the designed lead to cast iron to hold down the production costs. In some of the early boats, the weight was insufficient and internal ballast had to be fixed in the bilge. Then, after the molds had been made, the syndicate of sailors who had ordered the boats decided they wanted a masthead rig. It was too late to move the mast step aft the 24 inches that was required, so, instead, the mast was shortened and the jib stay was raised. Carl Alberg wasn’t pleased with the decision, but later admitted, “It seems to have worked out ok.”

After several other designs, including the Ensign (22 feet, 1600 built) were launched, he retired from the Coast Guard in 1963. About this time, Andrew Vavolotis asked him to design a 28-footer for Cape Dory. He’d already picked up the mold for the Typhoon from a bankrupt boatbuilder. This began a long association and a period when Carl Alberg designed at least one boat a year. In all, Carl designed 10 boats for Cape Dory, ranging from 19 to 45 feet. Vavolitis says,

“I always asked Carl to design me the beamiest and shallowest boat possible. Then he’d go away and what he came back with was what we used. Of course, it was never as beamy or as shallow as we liked. He never compromised his design principles.” Carl’s own assessment agrees:

“Contrasted to the modern IOR boats where you have six gorillas sitting on the weather rail with their feet hanging outside trying to keep the boat upright, my boats are strictly family-cruising boats. In all my designs I go for comfortable accommodations and a boat you can sail upright without scaring the life out of your family or friends. I gave them a good long keel, plenty of displacement and beam, and a fair amount of sail area so they can move.” In 1979, while those modern boats were capsizing and sinking, an Alberg 25 on it’s way to England comfortably lay a-hull.

“It was really blowing and though they shortened sails and did everything else they could in order to keep going, they eventually took everything off, went below, battened down the hatches and just ate, drank and played cards. When it had blown over they hoisted sail and continued to England, where they were told they had just sailed through the same gale that had taken 16 lives in the Fastnet race. They had ridden out the storm by just sitting in the cabin while everyone else was capsizing.” “There are still some designers around who share my ideas about glass boat design. Everyone else is trying to conform to the new rules. My boats are more designed to follow the waves and stay relatively dry and stable.” Carl passed away on August 31, 1986 at his home in Marblehead Massachusetts. His 56 designs resulted in over 10,000 boats.

Alfred “Bill” Luders (1909-1999)
Alfred “Bill” Luders was born 1909 and designed every Sea Sprite except the 23′.

Mr. Luders was a world class skipper in the 1930’s in the six meter racing class. Among the many famous yachts Mr. Luders designed was the sloop American Eagle, built for the America’s Cup competition. It was later owned by Ted Turner, the media tycoon.

Mr. Luders’ father founded Luders Marine Construction which produced more than 100 vessels for the United States during WWII. The company built minesweepers, patrol craft and submarine chasers.

After his father’s death, Mr. Luders continued to run the shipyard, building the America’s Cup boat Weatherly in 1958 to the design of Philip Rhodes. Weatherly was not a successful campaigner in that series, but after a redesign by Mr. Luders, she successfully defended the cup in 1964 with Bus Mossbacker at the helm.

Mr. Luders designed , and his shipyard built, many others yachts for owners such as King Olaf V of Norway, actor Yul Brenner, Nelson Rockefeller and the Pulitzer family.

The company closed in 1968 after changing technology and Fiberglass construction did not appeal to Mr. Luders. The last racing yachts designed and built by him were the 5.5 meter sloops, a class used in Olympic and international competition.

The Sea Sprite 34 was Bill Luders last design. He died January 3, 1999.
