Latest Survey

Survey done 2023

Survey Requested By: Captain owner

Attendants during the survey and sea trial: Undersigned marine surveyor and (1) Vessel owner.

Surveyed: While and on the hard at Shelter Island Boat Yard Shelter Island and on the water dockside at Marina and underway on San Diego Harbor San Diego, California.

Dates of Survey: June 2nd and July 14th, 2023

Owner: Captain owner

Replacement Value: $1,500,000 Present Value: $430,000

This is a 1958 Stephens 53 as found to be in very good/excellent condition with respect to exterior cosmetics/painted surfaces, interior housekeeping and furnishings, structural integrity, and general operation of mechanical, machinery, electrical, electronic, and plumbing equipment onboard. Vessel hull is white with tan canvas, (1) foredeck escape hatch port lights seals appear to be leak free and bilges dry to lowest pump pickup mostly towel dry. Vessel was sea trialed on San Diego Bay for a period of one hour and at that time a maximum rpm of 2,600 at 23 mph was achieved and maintained after which the vessel was operated at various rpms and performed as general usage would dictate.

This vessel is considered of suitable type for Southern California near coastal waters and like waters with respect to seasonal weather, conditions, and fuel range. Further notes and images below.

This vessel was originally built and commissioned for Marylou Jefferson, local San Diego philanthropist. In 2011, the vessel hull was completely refit to its original yacht quality of excellence by a local shipwright at Shelter Island Boat Yard here in San Diego. Main engines and generators were replaced, as well as many other upgrades were completed. Upon the passing of Marylou, the vessel was willed to Art (Jr.) Defever (DeFever Yachts), Art carried the responsibility of maintaining the vessel until his untimely passing. The new owner/operator has taken on the responsibility of maintaining the yacht to its high standard of integrity. The vessel remains a classic original and is in exceptional condition.

Below the water line zincs: (4) Shaft streamline type and (1) transom plate type zincs (new 06- 2023). Monitor zinc/bonding wires, ensure that all bonding wires connections are secure, service as needed. Note: Monitor all below the waterline metals for any excessive galvanic activity and adjust the amount of sacrificial zinc anodes accordingly.
