48' Home Made Chinese Junk

General Description

Thomas E. Colvin, NA Design 48' Ocean Cruising Auxiliary 3-masted Junk. She has a 5' Draft, and dual integral keel cooling. There is lots of headroom for a six-footer. This is a big, stable, tough, easily maintained, operator-friendly boat with a great deck layout, and a capacity to cruise anywhere in the world. Design anticipates easy crewing by a couple, and single-handed under sail or power is a viable option.

Actual Condition

It is reported, due to health reasons, the owner has suspended the project. All major steel construction has been completed, including grinding of all hull welds. The ship has also been sandblasted and painted.

There are well over 6,000 hours of construction into the Chinese Junk at this point. The hull, deck, bulwark, and cabin plate are high-strength low-alloy Corten Steel. The frames, keel shoe and t-bar are A-36. All steel is certified, and from USA Plants.

All plates were cut with plasma to preclude any warping. All welding was done with modern, inverter-based welding machines. The hull plate welds were triple welded with very high-quality filler metal. Generally, the interior welds were made with a dual shield mig process, and the exterior welds were made with a traditional stick process.

The rest of the work necessary to complete the project is primarily inside carpentry, plumbing, sail making and wiring. Almost all major parts, such as port lights, shaft, propeller, hatches, windlasses, masts, rigging, etc. are ready to bolt on to the hull now that the sandblasting and painting have been completed.

Equipment Included in the Package:

• Three masts approximately 11,000 pounds of 50-pound lead bricks custom-sized for the keel space.

• 22 Lewmar #1 Ocean Series Portlights with interior trim and screens. Cam action lock and friction hinges to hold at any angle. Approximately 8 3/8 inches by 16 1/2 inches overall (7x14), Lloyd's approved. ("Ocean Series" is the top of the line, Lloyd's rated, heavy duty equipment.) (Lewmar #398920500) Cabin is prepared to bolt these on.

• 22 Lewmar Ocean Series Deadlights for the above portlights. These deadlights attach from the inside to the portlight frame. Great safety feature, no crawling on deck in a storm to fit deadlights. (Lewmar #360053919)

• Two Bomar 24 inch by 24 inch cast deck hatches. These cast hatches are the top of the line, custom ordered, Bomar units, double hinged, with the ability to open from two sides so that you may ventilate whether the wind is from the bow or from the stern: they include 6 dogs/latches and the ability to be opened or closed from inside or on deck, as well as to be locked from the inside. (Base unit is #173, with custom nomenclature for extra latches, dogs, double hinges and inside/outside capability: l, D,O,W.) Deck is ready to bolt these on. (www.pompanette.com)

• Two Maxwell Model VWC 3500 pound capacity windlasses. One unit is hydraulic and one unit is electric. The electric unit includes a foot switch, remote roving hand held unit, reversing solenoid pack, and the breaker isolator panel. Each unit has a manual option in the event of power failure. Either unit can be converted to either electric or hydraulic power, and all parts are interchangeable. The purpose of different power sources is to provide options in the event of on-board power problems.

• Three drums of ACCO hot dipped galvanized hi-test chain (grade 4) sized for the chain wheels on the Maxwell windlesses: One 600 foot piece of 3/8 inch hi-test chain with big links at each end. One 350 foot piece of 1/2 inch hi-test chain with big links on each end. One drum of four lead chains to use with rope anchor lines. Again ACCO hi-test chain with large end links.

• Two heavy duty 1/2 inch rated Maxwell deck mounted chain stoppers.

• Four genuine BRUCE anchors, chosen because they have an almost 100% probability of immediately digging in when they are employed. Two 176 pounders and two 66 pounders. Bow and stern roller fittings have been sized to accommodate these units. These anchors are considered substantially oversize by most authorities, but the very heavy duty windlasses and the welded-on anchor handling gear are designed to make them very easy to use, and thus, another significant safety factor. Roller fittings have been galvanized and welded to the hull.

• The bow has a fitting just above the waterline to engage one, two or three nylon lines to act as snubbers on a chain anchor line.
