A very nice representation of Ted Irwin's MKIII 37 and in good condition considering her age. A few items stand out. First, the recently installed Yanmar 39 HP diesel is fresh and starts with the tap of a key. 500 hours. Looks clean and new. Second, her shoal draft makes her a very desirable cruiser. Third, her rigging, masts, all look recently tuned and are in fair to good condition. Fourth, her cockpit is very spacious and comfortable for long durations of time on the hook and cruising. Other areas of note: Her davit is a little light weight, but it functions well. Not designed for anything heavier than a light inflatable, but is serviceable. The wood mounting plates are deteriorated and need replaced with aluminum plates. Her swim platform is outstanding. Windlass is old and a manual unit. One house battery need replaced and is dragging the 12V down. Teak could use a sanding and recoating. Her fuel tank appears to be galvanized steel. Very little sign of rust, but should be checked out. Good news is it's a breeze to remove due to it's location beneath the removable salon floor. A few of the deck hatches could use some attention or replacement. Some are recently replaced and look good. Several of the other larger hatches are original, do not leak, but show signs of distress. We did not hoist the sails, so we do not have an assessment of the sail inventory condition, but owners are sailing her frequently and report no issues, and they are covered by canvas and out of the sun. She could use a haul out and bottom job. Last bottom job 2010. Diver cleans bottom every couple of months, so growth is not out of control. All in all. A nice boat with great accommodations. *NO AC or Generator.

1977 Irwin Yachts MK III 37 Center Cockpit Ketch

The MK III was one of Ted Irwin's next generation of sailing yachts, incorporating practical feedback and ideas from Irwin Owner's, something Ted was famous for, and supported by the latest fiberglass and boat building technology of her time.

The MK III's hull is a one-piece fiberglass unit using alternate hand laid layers of 24oz woven roving and reinforced with additional laminate in high stress areas to create a very solid hull construction.

This MK III is a full keel, shoal draft (4'), making her a perfect fit for island hopping in Florida and the Bahamas. She can skinny up to almost any anchorage to avoid the elements.

Her deck is a single piece fiberglass unit with marine plywood core for stiffening and insulation, covere ... [ask POP associate for the full description]
