Fatty Knees Information, Review, Specs

Sailing Performance & Handling

The handling characteristics of the Fatty Knees are defined by its hull shape, which features a full-bodied midsection and a relatively deep skeg. When rowing, the boat tracks with a precision rarely found in small dinghies, resisting the "crabbing" common in flat-bottomed designs. The lapstrake construction creates turbulence that acts almost like a grip on the water, providing stability when a passenger steps onto the gunwale.

Under sail, the Fatty Knees employs a simple but effective lug rig (or occasionally a marconi rig on certain vintage editions). Because it was designed by Lyle Hess, the boat possesses a surprising amount of "big boat" feel; it does not twitch or heel precariously at the slightest gust. Instead, it offers a predictable, stiff response. The 7-foot model is a nimble solo performer, while the 9-foot version is capable of carrying a small family and gear without losing its ability to beat to windward. The inclusion of a daggerboard trunk allows for efficient upwind angles, a rarity for a boat often relegated to "shore boat" duties. Owners frequently report that the boat sails well enough to be used as a primary daysailer for exploring harbors, rather than just a utilitarian transport tool.

Sibling Variants & Scale

The Fatty Knees was developed in three distinct sizes—7, 8, and 9 feet—each built on the same design philosophy but serving different roles:

• The 7-Foot Model: Originally intended as a "nesting" or compact solution for smaller cruisers, this model is a favorite for solo sailors. It weighs approximately 60 to 70 pounds (hull weight), making it manageable for on-deck storage on yachts under 30 feet.
• The 8-Foot Model: Often considered the "Goldilocks" of the range, the 8-footer balances a 3.5-foot beam with a weight of roughly 100 pounds. It is the most common variant found in the cruising community, offering enough buoyancy to carry three adults safely in moderate conditions.
• The 9-Foot Model: The heavyweight of the family, the 9-footer is a true expedition tender. With a broader beam and increased freeboard, it is frequently used by long-distance cruisers who need to transport heavy loads of fuel, water, and groceries in remote locations. It is also the most formidable under sail, often used for junior racing or coastal exploration.

Popular Mentions & Media

The Fatty Knees owes much of its legendary status to the endorsement of world-renowned circumnavigators Lin and Larry Pardey. In their books and videos, most notably throughout their voyages on Seraffyn and Taleisin, the Pardeys showcased an 8-foot Fatty Knees as their primary tender. They famously opted for the Fatty Knees because it could be rowed and sailed in conditions that would defeat an outboard-dependent inflatable. Their advocacy, detailed on the official Pardey website, helped cement the boat's reputation as the premier choice for "purist" cruisers who value self-reliance and traditional aesthetics.

Known Issues & Buyer’s Checklist

While the Fatty Knees is built to a high standard, there are specific areas potential buyers should inspect, particularly on older Edey & Duff hulls:

• The "Knees" and Woodwork: The boat’s name comes from the robust structural "knees" (thwart supports) that tie the seats to the hull. On older models, these were often made of teak or mahogany. If the varnish has been neglected, check for soft spots or rot where the wood meets the fiberglass.
• Daggerboard Trunk Wear: Because these boats are often dragged onto sandy beaches, the leading edge of the daggerboard trunk and the daggerboard itself can suffer from abrasion and gelcoat chips. Ensure the trunk is structurally sound and that there is no weeping of water into the hull laminate.
• Mast Step Stress: On boats that have been sailed hard, the mast step and the partners (where the mast passes through the thwart) should be inspected for stress cracks or compression damage.
• Towing Eye Reinforcement: Given its role as a tender, the bow eye (towing point) is a high-stress area. Look for "crazing" in the gelcoat around the eye, which may indicate the boat was towed in heavy seas without sufficient backing plates.

Community & Resources

The Fatty Knees community is tightly knit, largely supported by the current builder, the Fatty Knees Boat Company, which provides replacement parts, rigging diagrams, and technical support. Many owners also congregate within the broader Edey & Duff owner circles and the "Traditional Small Craft Association," where the boat is celebrated for its adherence to classic design principles. Technical documentation for rigging and maintenance is often shared via these owner associations to ensure vintage models remain seaworthy.

The Verdict

The Fatty Knees is a purposeful, heirloom-quality vessel that appeals to sailors who appreciate the intersection of form and function.

Pros:

• Exceptional Stability: The lapstrake hull and wide beam make it one of the safest small dinghies for boarding and heavy loading.
• Versatility: Superior performance as a rowing, sailing, and towing craft.
• Resale Value: Due to its reputation and the closure of the original builder, used models hold their value remarkably well.
• Aesthetic: A classic look that complements any traditional yacht.

Cons:

• Weight: Heavier than modern inflatables or carbon fiber tenders; usually requires a davit system or a dedicated deck space.
• Price: High initial cost due to the labor-intensive hand-laid construction and high-quality hardware.
• Maintenance: The teak trim and wooden sailing components require more upkeep than a utilitarian plastic boat.
