Planes & Sails

Airplane pilots are attracted to sailing because there are many skills that transfer between the two activities. For example, both require knowledge of navigation, weather, and wind patterns. Pilots can use their knowledge of aerodynamics to understand how to harness the power of the wind in sailing. Additionally, sailing can help pilots develop their situational…

Appropriate Freeboard

High freeboard improves buoyancy with no decrease in hull speed. Sailboats at rest with low freeboard only look faster than many of their high freeboard counterparts. Unless the boat has the general shape of a log, the heel of the vessel increases the freeboard presented to the wind. High freeboard presented to the wind when…

Lean Manufacturing

The notion of designing a vessel from a luxurious interior out doesn’t sit well with me, but this is likely the situation with most new sailboats today. In aircraft builds an approach called Lean is followed. This means that base functionality is engineered first before creature features (features that are intended to get a customer…

Competing Hull Forms Bethwaite

The competing hull forms in Murrelet (displacement in the bow and planing aft) bring up some interesting aspects in sailing the cruiser. Because the manufacturer built so many pocket cruisers, the best hull form and ballast configuration was extensively studied. For example, one contemplated factory modification in 2000, involved adding a platform to the transom…
