2019 SeaWind Handicap Regatta

GMBC SeaWind Handicap RegattaOn Sunday, 7 April 2019, we held a fun handicap regatta for SeaWinds.

It's common knowledge that although the SeaWind class is raced internationally as a one-design class, there have been four different versions of this model made by Kyosho over the years, and although they all look alike, in the words of George Orwell, "some are more equal than others."

SeaWinds have been manufactured in Japan with ABS (plastic) hulls, fibreglass hulls and carbon fibre hulls. After the Kyosho factory in Japan was damaged by the 2011 earthquake and tsunami, production was moved to China where ABS hulls are now made. All four of these hulls vary in weight and just to make things even more interesting, there are two different keel bulb designs in lead and steel versions.

In our Club we can see variations of as much as 500g between boats - that's almost 30% overweight!  

In order to see what would happen to performance if we leveled the playing field, we put together a day with a difference! Unfortunately our plans were negatively influenced by underwater debris fouling keels, and by a lack of wind as the day progressed. Nevertheless, a great time was had by all!

To start with, we weighed all the boats to see what the spread of weight differences was. (The boats in italics were not at the regatta but their results are added for reference purposes.)

Then we asked the question: "Is it you or your boat which is quick?" We held three short, one-lap races where the skipper who finished first in the above results swopped with the last boat, and the second-fastest swopped with the second last, and so on. Interestingly, once racing got under way, there were very few instances of skippers sailing the wrong boat!

Lastly, we added ballast in the form of nuts and washers inside every boat to bring them all up to the weight of the heaviest boat in the fleet - 3.383 kg. There was much light-hearted complaining about 'submarines' and increased waterlines, but we all took on the challenge with enthusiasm. Unfortunately the wind was much less enthusiastic and we drifted around hoping to catch a puff.

The results showed that skippers who sail heavy boats can get to the top of the score sheet once the fleet has been equalised. Congratulations to Bernie, Ian and Neil for getting the podiums!
