Design and Construction
Reichel/Pugh drew a relatively wide hull with a length-to-beam ratio of 3.42. The canoe-body profile shows the forefoot lifted just above the design waterline, leading into a near-plumb stem. The rocker flattens around the keel root, then kicks up around station 7.5. The shape pairs with very high-aspect-ratio fins for the rudder and keel.
The keel itself is a cast stainless fin carrying a lead bulb. A built-in kelp cutter at the leading edge allows weed to shear off quickly, while a large fillet smooths the junction between the hull and the keel’s leading edge. Ballast includes 8,820 pounds of lead cast to the bottom of the fin, plus 2,980 pounds of water ballast held in two tanks per side.
Tillotson Pearson built the hull with carbon-fiber woven biaxial fabrics for the inner skin and Kevlar-and-glass hybrid fabrics for the outer skins. All were wetted out with custom-formulated Ampreg epoxy. The keel floors and longitudinals are solid carbon-fiber and glass over a foam core, glassed integrally with the hull. The deck is all carbon over foam, with integral beams. The all-carbon-fiber rudder and stock are by GMT, with Speedwave bearings. These are exotic, lightweight structures for a 48-footer.
Rig and Deck Layout
The fractional sloop rig carries 1,194 square feet of sail area, giving the D 48 a sail-area-to-displacement ratio of 27.98. It centers on a carbon-fiber mast by Sparcraft; the masthead unit, gooseneck, and vang bracket are also cast in carbon-fiber. The boom is a two-piece section that combines an extruded top with a shaped bottom.
All deck hardware is from Lewmar. Ultralight primary winches connect to a lightweight centerline pedestal, an arrangement that keeps mass centered and helps the crew move efficiently.
Systems and Accommodations
The D 48 is a racer first, reflected in its modest tankage: 21.4 gallons of diesel and 41.5 gallons of water. Auxiliary power comes from a Yanmar 3JH2-TCAE X SD31.
Instrumentation is extensive and entirely from Ockam. The listed equipment includes full polar readouts, fitting a boat intended to be sailed to targets rather than cruised.
Verdict
The D 48 is a narrowly focused grand prix one-design, built with exotic composites and equipped with a high-aspect bulb keel, an integral kelp cutter, and a carbon rig from a specialist manufacturer. With only eight built, it’s a rare sight. Its water-ballast system and comprehensive race instrumentation mark it as a serious course weapon rather than a weekend cruiser.
Pros
- Carbon-and-Kevlar hybrid hull in custom epoxy, with an integrally glassed carbon keel structure
- High-aspect cast stainless fin keel with a lead bulb and built-in kelp cutter
- Carbon-fiber mast and carbon-fiber boom hardware
- Full Ockam instrumentation, including polar readouts
Cons
- Just 21.4 gallons of fuel and 41.5 gallons of water, giving minimal cruising range
- Only eight built, so spares and class support are limited
- Water-ballast system adds complexity compared with a simpler lead-ballast racer
