About the 1947 Custom 42 Trawler

If you are looking for a classic wooden boat to cruise the Pacific Northwest Diligence is a well loved, solid, boat that can take you anywhere you want to go.

The owner has been fitting out the boat with a plan to head to Alaska but life circumstances have changed and he needs to sell after spending roughly $60,000 on maintenance and upgrades in the past two years to ensure Diligence is a safe and reliable vessel.

The majority of the money was spent on ensuring the underwater portion of the hull was in great shape. Diligence was thoroughly inspected, all planks needing replacement were replaced, the hull was fully re-fastened, re-caulked and painted. All done by one of the best wooden boat companies on the island. .

The owner has had a two-mechanic team going through the Gardner diesel and surrounding systems and ensuring all maintenance items have been addressed, access has been improved and she is working well.

Originally converted from a fishing boat to a pleasure craft in the early 80’s. A complete refit began in the late 80’s and by the early 90’s, Diligence had all new electrical systems and wiring, new fuel and water tanks, new plumbing, hydraulics, and the engine rebuilt. Diligence has a long history ot continuous upgrades with hundreds of thousands of dollars being invested over the years by previous owners to keep her in top shape.

Since 1989 she was professionally maintained by Richmond Boat Works Portland Or., Charlot Marine Works Inc. Portland Or. and D. W. Charlot Shipwrights LLC until her sale to the current owner who brought her up the west coast from Ilwaco Washington and has continued to ensure Diligence is kept in the condition she deserves. Its important to note, the delivery skipper that drove Diligence from Ilwaco, on the Columbia River, up the west coast of Washington to Sidney BC, had no concerns about her strength, sea keeping abilities, engine reliability or overall abilities.

If you like classic boats and want one where the important and expensive work has been recently completed, Diligence is being offered at a very fair price with the intention of getting her a new home.


Engine & Running Gear

The Gardner diesel is considered one of the best work-horses ever built. Compared to modern 120 hp engines, she is a beast. Massive, strong, capable and will simply keep on working. The engine room is from a time when access was considered an extremely important safety feature so there is full walk around space on both sides. With clean fuel, clean oil and well maintained cooling, she has many years left in her.

Historical Maintenance

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.

In 2015. Starter was replaced new and all cable connections to it. Batteries: All 8 batteries for the 2 bank 32v system batteries were replaced. Then Summer touch up work to exterior paint and coating were done.

In April 2016 She was hauled out and put into Port Ilwaco Boat Yard Building for 3 weeks for refinish work to hull, below and above water and top side paint. 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. Inside bulwarks re-painted. All Ironwood rub-rails sanded & treated with 3 coats of Humboldt/Seafin Oil coating. 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. Bottom appears tight and fair, for it is a heavy stout vessel that was well made for commercial use. Engine operation perfect, fuel good clean, filters replaced 50 hours, system operations are well found.
