All hulls are not created equally.

All too often basic hull forms will be recycled over and over rather than creating the optimum shape for each different type vessel. Time constraints, R & D costs and experience or lack thereof are generally the deterrents.

At OYD, we optimize the hull form for the intended purpose of each specific project. From displacement to planing, from hard chine to round bilge we have developed a vast design library of highly refined, proven hull forms over the past 25 years.


Our semidisplacement motor-yachts are based on our deep forefoot, hard chine, relatively shallow draft hulls with semi-tunnels. These vessels display excellent seakeeping while maintaining a modest draft, ideal for areas like the Bahamas.


Our MARINER, ALLERGO and DAUNTLESS designs as well as well as our Chaperone support vessels are all built on our "Fast Displacement" (FD) hull. These highly evolved bulbous bow, round bilge full displacement hulls easily exceed a speed/length rato 1.6 as compared to a more common 1.3 SLR. When operating at slower conventional displacement speeds, these hulls are real fuel mizers. Now on our third generation with over a decade of refinements, these are truly world class, go-anywhere vessels with extraodinary seakeeping and comfort.

Our full displacement, hard chine hulls offer a less costly option to base a motoryacht or explorer on. While lacking the superior performance of our FD hulls, this is a practical solution when initial build cost is the priority. This is a widely used type hull form throughout the industry.

Our soft chine, bulbous bow full displacement hull is a good comprimise between the hard chine displacement and the "Fast Displacement" hulls. These offer increased efficiency, seakeeping and comfort over the hard chine hull while still more economical to build than the FD.
