Built by Ryder Boats in Bucksport, Maine, the Presto 30 is a lightweight performance craft built with modern composite construction and assembly techniques.

Hull: The VARTM (vacuum-assisted resin transfer molding) hull is built with vinylester resin, NCS (non-crimp structural) E-glass, and Corecell A500 core. The bow is reinforced with aramid patches in case of accidental collisions. VARTM, also called vacuum infusion, is a closed-molding technique that increases the glass-to-resin ratio, ensures the laminate is consistent and free of voids, and produces a lighter, stronger part.

Deck: The hand-laid deck is built with polyester resin for better cosmetics, NCS E-glass, and vacuum-bagged Corecell A-500. High-density core is used in way of highly-loaded, through-bolted hardware, and epoxy (G-10) plates are laminated into the deck for tapped fittings.

Hull-to-deck joint: The modified shoebox hull-to-deck joint is bonded with Plexus (methacrylate structural adhesive) and through-bolted with ¼-inch stainless-steel bolts.

Keel and rudder: The centerboard and rudder are vinylester/E-glass composite construction. The centerboard has 90 pounds of lead embedded in syntactic putty to add enough weight to keep the centerboard down while underway. The rudder gudgeons and rudder head are carbon-fiber/epoxy construction.

Rig: The Presto 30 has two bilge-stepped, carbon-fiber, free-standing spars. They are supported by mast tubes glassed to the hull and deck structure with unidirectional E-glass.
