The Gadflyis one of a large number of GRP (glass reinforced plastic) boats built in Taiwan, primarily for the US market and based on a design by Bill Garden.  Large numbers of these boats were built in Taiwan in the 70’s and 80’s, in a number of yards and with a variety of design features and names.  Gadfly is a ‘Sea-Tiger’ and was built and launched in 1975 at the Formosa Boat Building Co. yard in Taipei. She spent most of her early career in Seattle and Alaska in the United States before going to New Zealand and then Australia.  She has journeyed apparently around the world, then across the Pacific, New Zealand and in the past seven years with her current skipper in SW Pacific locations, and SE Australia.

According to the Builder’s certificate she is measured at 40’11’’ in length, 12’ 2’’ width and 6’2’’ depth; net tonnage 14 (US).  She is rigged as a cutter-ketch and has a Westerbeke W58, 60 HP engine.  This is a marine version of a Mazda XA light truck engine. She sleeps up to eight in two double berths and four single berths but really three to five is a good number for longer passages!  The rig is Genoa (high cut ‘Yankee’ about a number 3) and staysail, both on furlers.  The forestay is attached on a bowsprit with decking-platform to the pullpit. The main and mizzen are slab reefed, three in the main and two in the mizzen; reefing is ‘at the mast’.  She also carries a large light-wind, light-weight cruising genoa, MPS in a sock, spare staysail and storm trysail.  Main and mizzen are covered with sail bag and lazy-jacks. Gadfly has wheel steering, chain-cable to rudder. She has a full length keel and keel hung rudder.

She carries 270 litres of diesel in a midship fuel tank, 180 litres in two fuel bladders and 60 litres in three jerry cans stored outboard over the transom.  There are two water tanks (isolated), located underneath the saloon berths each at 160 litres.  Gadfly also carries a PUR 80E water maker.  A three burner gas stove is supplied from gas bottles carried in an aft locker that drains through the transom. Refridgeration is 12 volt, electric, house batteries are 2x200amphr, AGM, cranking/engine is 2x80amphr, sealed lead-acid.

    I could use some open ocean sailing experience and came across your posting on 7knots. Can you spell out what your itinerary is for 2011. I would be available after the first week in January. And what is the cost. Where can I board? etc.

      Hi Raivo, thanks for the message. Tentative plan is to head east in the early part of next year. Might get into the passage east rally for the journey over the top of Borneo. Tentative plan is to get back onto Aus east coast for a move south when the northerlies kick in late next year. So on the water for at least another year or who knows maybe longer. See how it all goes. What are your plans? I see you have a 5 month sojourn planned, how is that going together? Cheers and beers, Trevor.
