and his team cruised and won some races in the Adriatic. As they expected light winds the boat was built particularly lightly. However they had to sail from Cork, Ireland to Trieste and met some particularly tough weather on the way. (Info from V. Delany).

2014 Septembre, For Sale, Silver Shamrock is Ron Holland’s 1976 Half-Ton World Cup winner K/GBR 5253 (??) helmed by Harold Cudmore. She has had a very successful racing career but I have not raced her since my retirement in 2000. Regretfully she is now for sale due to my age (75), she is a boat for a younger person and an absolute bargain at this price. I was preparing her for the 2012 half-ton cup when circumstances prevented me from taking part, hence there are two new, unused spinnakers and a virtually new Mylar No. 1 Genoa, a new Tuffluff twin groove headfoil and prefeeder plus a range of older sails. The rig and kicker are tensioned by hydraulics. The masthead tricolour was new last year. She is laid up for six winter months every year on a bespoke, eight point screw jack, lay-up cradle which can be taken apart and carried on a small trailer. All instruments and equipment are removed during lay-up and stored in a dry environment, Rating:- Endorsed TCC = 0.911 (in 1999 not raced since 2000), Winches:- All Lewmar. Genoa = 2 x 43 x 2 speed.(little used since new) Spi/Genoa halyard 2 x 40 x 2 speed. Reef/Halyard = 2 x 25 x 2 speed. There is a good range of instruments:- Raymarine ST60 wind. ST50+ CH/VMG. ST50+ Log. ST50+ Depth. VHF radio. GPS Eagle view. ST2000+ Tiller pilot. Car type FM radio. Compasses:- 2 x Plastimo bulkhead. Recent, V good condition, Anchors:- 1 x CQR. 1 x Admiralty pattern.

September, from Vincent, "She has a new owner based in Howth Yacht Club. She has been given a new livery, but otherwise she seems to be in original setup. the new owner wants to get to know the boat and to play with her.
We wish him all the best. There is of course extensive skill in sailing these boats within Howth Yacht Club which was once the home of Demelza (still is), Raparee, and Golden Leprechaun.
