Island Packet sailboats: a full-keel cruising identity built by one naval architect
Island Packet's sailboats carry a design signature that traces back to a single naval architect's career rather than a rotating cast of stylists. Bob Johnson founded the company in 1979 as Traditional Watercraft, Inc., and for nearly four decades his patented Full Foil Keel and hand-laminated solid-fiberglass construction defined every hull the yard built, from a 26-foot centerboarder to the largest center-cockpit cruisers. That continuity survived a 2017 change of ownership and remains the throughline connecting Island Packet's earliest boats to its newest ones.
Origins and ownership
Johnson formally incorporated Traditional Watercraft, Inc. in the fall of 1979 and, a year after launching the 21-foot Lightfoot, bought the liquidated molds for the Bombay Express and reworked them into his first Island Packet: a beamy, 26-foot centerboarder that launched in 1980. A Mark II introduced at the February 1982 Miami boat show added more headroom and the first version of the Full Foil Keel. The Island Packet 31 followed in 1983 — orders for 14 boats were taken at that year's U.S. Sailboat Show in Annapolis, and the model stayed in production until 1989 after 262 hulls were built. In 1984 the original 26 evolved into the full-keel Island Packet 27, which ran through 1992 with 249 hulls built. Over the following decades, Johnson designed 24 different Island Packet models in total, and the company's cumulative output has topped 2,500 yachts.
Johnson remained founder, CEO, and chief designer until the company changed hands in two separate steps rather than one sale. In April 2016, Hake Marine, parent of Seaward Yachts, acquired the company, consolidating two longtime Florida builders that had already joined forces the year before; Seaward's Stuart, Florida production facility closed and its molds moved to the Island Packet yard in Largo. Only in January 2017 did Darrell and Leslie Allen become Hake Marine's new majority shareholders and managing partners, at which point the company was renamed Island Packet and Seaward Yachts. The Allens were not outsiders — their Suncoast Yachts dealership had represented Island Packet in San Diego for more than two decades. Their early moves included rolling model pricing back to 2008 levels, consolidating two production facilities into one, and rebuilding the workforce from 13 employees to more than 50, many returning Island Packet craftsmen.
The designers
Before boats, Johnson spent two years at McDonnell Douglas working on ballistic missiles, then followed his own ambitions to southwest Florida in 1974, joining Irwin Yachts as a naval architect under production-boatbuilding pioneer Ted Irwin and modifying existing Irwin hulls including the 30 and 33. There he became close friends with fellow designer Walt Scott. After two years running the Irwin plant, Johnson moved to Endeavour, an Irwin offshoot staffed by former Irwin employees, where he designed the Endeavour 43 from scratch along with the Endeavour 40 and the Stamas 44.
The Island Packet itself began with a favor to that friendship: the Bombay Express, whose molds Johnson later bought out of liquidation, had been designed by Scott as a beamy cat sloop for Bombay Yachts. Johnson reworked it into his own boat rather than building Scott's design as-is. He also named his own keel — the Full Foil Keel, an airfoil of roughly 6.5-to-7-percent thickness built into the hull rather than bolted to it, its ballast capped internally to form what Johnson calls a double bottom. Separately, Bob Cottrell of Arjay Industries developed a spray-applied core material that eliminated the need for foam, balsa, or plywood in decking; Island Packet later acquired it, marketed it as PolyCore, and backed it with a 10-year warranty.
In 2013, Johnson collaborated with longtime Tartan Yachts designer Tim Jackett on the Blue Jacket 40, named Cruising World's 2014 Domestic Boat of the Year. He was protective of how his work was judged: he once returned a Boat of the Year trophy his company had won because he considered the accompanying review unfairly unflattering. Since the 2017 ownership change, new models have come from an in-house Island Packet Design Team rather than from Johnson.
Construction through the eras
Every Island Packet hull is a one-piece, hand-laminated solid-fiberglass hull and keel reinforced with triaxial knitted laminate, with no balsa or foam core in the hull itself. Decks use PolyCore, and interior construction relies on Coosa composite board instead of marine plywood. Every Island Packet yacht meets CE Category Standard A for Ocean, the rating for extended voyages in conditions that may exceed Beaufort force 8.
Chainplates mark the clearest visible change over time. Earlier boats had chainplates embedded directly in the laminate, and some later failed because stainless steel needs air exposure to stay stainless; the current specification is a "belt and suspender" bonded chainplate in 316L annealed stainless steel. The standard rig shifted too. For roughly three decades, the sail plan was a cutter rig with a high-cut foresail and a furling working staysail set on a Hoyt Jib Boom, paired with a signature teak caprail carried for more than 30 years — both dropped when the Estero arrived. Sales data cited by former vice president of sales and marketing Bill Bolin also points to a shift toward in-mast furling, with the company selling few if any boats with conventional full-battened mainsails between 2004 and 2012.
Lines and generations
Most of the lineup, from the Island Packet 27 through the larger cutter-rigged cruisers, follows the full-keel formula Johnson established early on; the Island Packet 460, with its trademark off-white hull and Hoyt-boomed staysail, carried that formula to Cruising World's 2009 Domestic Boat of the Year award. The 2007 SP Cruiser broke from the pattern with a broader, trawler-styled transom and swim platform built around motoring comfort. The 2009 Estero was a more fundamental departure, dropping the decades-old teak caprail and cutter-rig convention; the 2019 Island Packet 349, built explicitly as "a re-boot of the old Estero," was named Cruising World's 2019 Domestic Boat of the Year. The 2021 Island Packet 439, Cruising World's 2021 Best Full Size Cruiser of the Year, reused the same Johnson-designed hull as the older 440 and 460 models but was developed by the in-house Design Team under Allen-era ownership.
Who Island Packet is for
Practical Sailor has described the Johnson-era lineup as dominated by full-keel auxiliary sailboats with a U-shaped hull, a conservative ballast-displacement ratio, and a low-aspect rig — a consistent philosophy across 24 designs rather than a boat-by-boat reinvention. Every model meeting CE Category A for Ocean underscores that the boats were built for extended, open-water voyaging. The brand's history is documented outside the company itself, too: Island Packet is featured in Ferenc Mate's book "The World's Best Sailboats II," and its cumulative output of more than 2,500 yachts spans two ownership eras built on the same keel philosophy.
