" Cavileah " offers upgraded Caterpillar diesels, Naiad stabilizers, and a Honey Oak interior.

Her overall condition is still good, but one engine is in need of a rebuild.

Owner is offering the boat "as is" with estimates for repair, or repower available, from reputable local dealer.

Westbay 58's were performance oriented yachts with a rock-solid ride that were engineered to the highest North American standards. A solidly built, luxurious cruising machine, she is big enough to entertain a large group with many of the features of a large yacht, yet small enough for a couple to handle comfortably.


This is a three stateroom, galley up, Pilothouse Motor Yacht with a wide beam, spacious salon, walk-around side decks and a large cockpit aft. Honey Oak interior finish. VIP guest stateroom forward.

From aft: The 7-foot cockpit is big enough for "Al Fresco" dining or serious water sports activities. There is a large molded-in dive platform accessed via walk-through transom door, a stainless steel ladder leading up to the flybridge/boat deck, and steps leading forward on both sides to the wide side-decks. An opening hatch, leading to a stairwell, allows access to the stand-up engine room, and aft is a separate hatch for the huge lazarette. Double doors lead forward to the salon, and forward and up three steps is the "country style" galley with dinette, and the pilothouse controls.

The Pilothouse with full helm station is located forward of the galley. A stainless steel destroyer wheel is center line at the console and the helm chair is mounted just aft. Port and starboard pocket doors lead to the wide side-decks.

A curved oak stairway allows easy internal access to the flybridge from the pilothouse. Forward and down three steps from the pilothouse are the owner and (two) guest staterooms, two heads with showers and the laundry center. The master is full beam amidships, and all the way forward is a VIP queen berth on center-line. The third stateroom has two over/under berths.

Flybridge: The Bridge features a full helm station beneath a large Bimini top (new in 2020), two pedestal mounted helm chairs and two L-shaped settees with seating for eight. Aft of the settees is the boat deck with low profile crane.

Salon: Entering the main salon from the cockpit through double wide doors is well furnished salon with a sofa to port and three chairs opposite. There are large windows with blinds, fitted vinyl headliners with flush-mounted halogen lighting. The double doors open aft, and visibility forward is excellent creating an nearly unobstructed flow from transom to pilothouse.

Forward of the salon and up three steps enter the pilothouse and galley level. To starboard is the curved, hand crafted oak stairway to the flybridge.

Galley: The galley is opposite the dinette and on the same level as the pilothouse. The Corian surfaces offset against the honey oak-faced appliances, and features all of the factory options, including upgraded faucets and fixtures. Additional storage for dry goods is located under the bench seats of the settee.

The Dinette is on the starboard side with a Corian-topped table and L-shaped settee for four, plus storage for plates and glassware housed within. Additional storage for dry goods is located under the bench seats of the settee.

The Full Width Master Stateroom is down and amidships, aft of the staircase from the pilothouse. There is a head with large stall shower, center-line queen berth with storage beneath, oak wood nightstands, brass reading lamps and upgraded bedspread, throw pillows, shams and blinds. A stacked Westinghouse washer and dryer are housed inside a closet forward in the master stateroom. This stateroom has individual air-conditioning controls.

The VIP Guest Stateroom is all the way forward from the master and features a queen-size berth on center-line. This comfortable stateroom has the factory optional mirrored oak storage cabinets built in overhead on both port and starboard sides. A chest of drawers, cedar lined hanging locker and storage for suitcases is provided in lockers beneath the berth. Two opening overhead hatches provide bright natural lighting by day or a direct view of the stars at night. Two brass reading lamps are mounted to the headboard.

The Second Guest Stateroom is to port, offering over/under single berths with reading lamps, a hanging locker, and drawer storage. There is access to the shared guest head including stall shower, mirrored vanity and wood laminate flooring.
