This info comes via the previous owner as well as the shipwright that maintained the boat and a 2019 survey:
Diligence is a very stout, heavy built well taken care of vessel through its years to this day. It was decommissioned as a fishing boat in the northwest by 1979 and then converted to a pleasure craft trawler for recreational use by 1982, then enjoyed by its owners, hence. Later acquired by Charlot Marine Works Inc. Portland Oregon. Then the exterior and interior was refinished and additions and updates made by Charlot Marine Work Inc. Diligence has been shown over the years on several seasons at the Port Townsend Wooden Boat Festival and several times and in Portland Oregon and Coastal Boat shows. An extensive refit conversion to the entire boat was done by 1982 with all total electrical systems and wiring, new plumbing, and running gear serviced, hydraulics replaced, woodwork serviced, corking renewed and semi refastened as to hull. The engine was rebuilt and serviced by Gardner Vancouver BC during original conversion period and all the water and fuel tanks were pulled and new tanks installed at that time also. Since then the boat has been professionally cared for through the years since 1989 by: Richmond Boat Works Portland Or. - Charlot Marine Works Inc. Portland Or. and D.W.Charlot Shipwrights LLC. She has been hauled out every 2 -3 years for general service i.e., bottom paint, zinc, general maintenance and complete refinishing or as needed. Diligence is a show piece for sure, comfortable, secure, warm and cozy, but a very trustworthy usable stout vessel for the pacific coast and inland waters.
In April 2013 the vessel had completed a total exterior refinishing, paint and body and repairs to seams, various woodwork needs, gear serviced, new zinc and bonding system check. Over one month of professional and owner contribution work completed in dry dock building totaling about 840man hours. Head serviced, packing gland serviced, fluid changes to engine, gear, hydraulics, keel cooler cleaned, pilothouse windows removed and re-bedded. Bilge cleaned. During this time the hull structure was sounded and probed and plank fasteners were randomly inspected and found sound. Back in water all systems checked. The vessel is at this time in total operation and sound. 2014. New Garmin Radar/Plotter/GPS installed with custom aluminum pedestal mount.

New zinc was welded and bolted to the hull , galvanic AC/DC potential reading was total bonded and in perimeters. All valves serviced and proven fit, working, and sound. Cutlass bearing shows no wear, prop is sound condition, rudder sound and responsive. Hull appears true to her lines and fair. No bilge water was leaking out when on dry dock stands. A few feet of garboard seams were reefed out and re-cocked and a thru hull & valve not used anymore was removed. 2 coats Unipoxy Red anti-foul applied with 3 coats on waterline and bow ad rudder, 5 gallons total applied. 2 coats Interlux Brightside enamel finish colors to hull. 3 coats of Elastomeric nonskid deck coating to cabin tops and main walking decks was applied.

The underwater hull seams were checked and some areas midships garboard keel were reefed and re-corked as found necessary due to slight seepage of bilge water. These seems are tight and secure. Keel cooler was inspected and cleaned, found sound. Keel straight, no hog or distortion, wood hard and no damage, skid shoe sound, boat dose not flex at all when in lift straps ever was found and no seams opened.
