San Juan 48' Sedan

Propulsion and Ride

The 48’s propulsion system plays a major role in her performance. Rather than the waterjets and computerized joystick-type engine controls that hallmark boats from competing companies, San Juan opts for a straight forward approach: inboard diesels routed through close-coupled V-drives to straight shafts, with big props in tunnels and big rudders for lots of steering control, especially in following seas. Single-lever DDEC electronic sticks at the helm put the finishing touches on the package.

Drivetrain simplicity alone has little to do with the smoothness of the 48’s open-water ride or her cornering agility, however. Instead, the key is the savvy way the system was designed, built, and installed. Consider, for example, the 7’5″ breadth between the props, as well as the rudders, a design element that boosts turning leverage and maneuvering oomph big-time. And then, not only does the boat’s Marol rotary-actuated hydraulics make steering fingertip easy, the system mechanically blocks rudder chatter from the helm and obviates wheel creep, in turns as well as on the straightaway. To further enhance smoothness, rudder stocks are stabilized in gutsy stainless steel fabrications bolted into stainless steel plates that are laminated into massive hull foundations during the infusion process.

Her twin MTU Series 60's cruise her at a exhilarating 22-24 knots, burning an economical 36 gallons per hour or 1.5 gallons per mile. Her top speed is near 40 knots!

Accomodations

The 48’s interior layout is as elegantly simple as everything else onboard. There’s a full wet bar on the bridge deck abaft the helm seat with 2022 U-Line refrigerator/ice maker, a U-shape settee and table opposite of here, wide sun lounges aft, and a bench seat across the transom. Below decks, the owner's stateroom is ample as well as comfortable, a separate stall shower in the en-suite head and a SeaLand “direct fall” MSD, meaning both it and the MSD in the day head across the hall open directly into the holding tank below—no macerators, sanitary runs, or other complicating factors are installed between bowl and tank. The guest stateroom, with a queen berth and fold-down pilot berth rendered private by pocket doors, is opposite the U-shape galley and is the real showpiece of the teak-trimmed accommodation area. With doors retracted and the berth converted to a couch-potato-friendly lounge strategically positioned in view of flat-screen TV, it does double duty as an entertainment area.

Construction

The San Juan 48 is composed of just four basic parts: hull, deck, interior liner, and superstructure. All are vacuum-infused using pricey E-glass, CoreCell coring, a high-end hybrid epoxy-vinylester resin, and in the hull alone, lots of impact-resistant Kevlar. Combine such a highly technical, lightweight assemblage into a single, unibody chunk, add four, cored-glass, watertight structural bulkheads, a PVC foam-filled E-glass stringer grid, and a box-type hull-to-deck joint, both chemically bonded and mechanically fastened, and what results is a sensation of pure, velvet-gloved brawn underway, despite the boat having a mere 32,000-pound displacement.
