The North Pacific 45 is designed with a reverse rake pilothouse and bold look to reflect the true capability and function of this long-range coastal cruiser. There is no wood on the exterior of the NP45, only stainless steel, fiberglass, and a durable Flexiteek deck for reduced maintenance and ease of ownership.

The hard chine hull was carefully designed to provide good stability and economy at low-end speeds while providing lift to allow for higher top end speeds when larger engines are chosen. A keel allows the vessel to track well but you remain in full control at any speed with a large barn door style rudder that, along with the shaft and propeller, is fully protected. The planked look embedded in the fiberglass adds to the character and classic look.

The superstructure is made of fiberglass and cored mostly with a synthetic lightweight closed cell foam, which increases stability and eliminates the possibility of rotten decks. Rigid PVC squares are used in areas that require more strength (where the upper helm seat is bolted for example). The hull and superstructure are a shoebox design and are epoxied and fiberglassed together for a strong and lasting bond.

The hull is solid, hand-laid fiberglass. This makes it both very strong and heavy, which adds to the stability. A vinyl ester resin is used in the outer two layers of the hull to prevent blistering. Below the waterline is additional protection in the form of an epoxy barrier. The stringer grid on the NP45 is exceptionally rigid, increasing the hull strength. Stringers are made on a separate mold and then glassed into the hull, eliminating the need for coring.
