The 58' Sonship built by West Bay in British Columbia is their most popular model, it offers a blend of classic styling with a modern pilot house, luxurious accommodations, and world class construction. Built on a modified–V hull for speed, it features Airex coring for strength, prop pockets for a shallow draft, and under water exhaust for quiet and reduced fumes.

Exteriors include a good-sized cockpit with lazarette storage, walk-around side decks, and a spacious flybridge with 2 L-lounges with 2 cocktail tables.

The yacht's exceptionally roomy open-plan interior afforded by its 17' beam offers three staterooms that sleep 6 and two heads. An amidships full-beam master stateroom with walk-around queen berth, a luxurious salon furnished with large U-shaped sofa and hidden entertainment center, an extended pilothouse with full-service galley and dinette, and a standup engine room with cockpit access are its highlights.

The 58 West Bay Sonship is a three stateroom, raised pilothouse motor yacht with cockpit, walk-around side decks and flybridge, and offers one of the finest interior arrangements of any similar type yacht. The interior woodwork is crafted in satin varnished American Cherry with high gloss corner posts. Teak & Holly flooring graces the galley/pilothouse area and heads while the remaining floors are covered in carpet with a sound deadening underlayment. All fabrics, wall coverings, carpets, bedspreads, and pillow shams as well as other linens and decor items have been upgraded from standard to superior quality. Closets and hanging lockers are lined with aromatic cedar. Windows on the main deck are of gray tinted, heat-treated laminated glass. All living spaces offer opening ports, overhead hatches, or sliding windows for natural ventilation. Four, zone-direct expansion air conditioning and heating systems provide supreme indoor comfort.

The white hull is vacuum bonded, hand laid up fiberglass Knytex and BTI with a 1" core cell, urethane foam core fiberglass stringers, and ISO Aristech resin osmosis protection below the waterline. The deck is cored, as are all bulkheads. Barium filled foam composite laminate in the engine room bulkheads and overhead provide sound insulation. Bilges and machinery spaces are finished with epoxy paint for ease of maintenance. The boot stripe is 2" black Imron and bottom is finished with Interlux 2000/2001 epoxy barrier and Micron CSC extra anti fouling paint.

The hull is protected with a rub rail capped with a stainless-steel striker. All handrails and rail fittings are 1-1/4'" 316 stainless. There are twelve cleats: 4 bow, 2 stern, 4 springline and 2 flush popups on the swim platform. An anchor platform with bow roller is fitted on the foredeck. Propeller shafts and hydrodynamic rudders are stainless steel.
