The next boat

Well here we are again … staring down the face of another moth build.

How did this all come about?

Well since the Belmont worlds, I have know for a while that I have needed a new boat, I also know that moth sailing is not the only expense that I have, so slapping down $20K+ for a mach 2 whilst nice, it simply is not an option. So what do you do in those circumstances? You wait. You wait until either the second hand resale price comes down, a great opportunity comes along or you home build.

This boat is a bit of both the last two and I have Clive Watts of CST to thank for that. Clive offered me a “winter build project”, which I simply could not refuse. This boat is a Monstro, the last of the R&D production run of three boats made by CST. So this is a “sister ship” to Nathan’s red and white “Artemis” moth made by Dave Lister, and another owned by Pete Valpiani.

The quality of the parts are awesome and way better than anything I could make at home. They are all pre-preg over a nomex core and weigh nothing (well not actually nothing, but they are bloody light).

First job off the rank is to put the new boat aside and make some cradles. I am going to re-use my cradle from my current boat on the new one, so today’s job was to get my previous cradle and update it to take the mouldings from my current one.

(The cradle needs to be made first so you have something to put the hull in once construction gets underway).

I have yet to make up the Montsro mouldings, so that will be my first job next weekend before moving onto the next job … the centre case.

Making Significant Gains

One thing about having an open data stream for the Americas Cup means that there is nowhere to hide when it comes to how fast you are going around the course.

Over the weekend I managed to stumble across www.cupinfo.com, a site that collects all the data and creates polar graphs of the AC competitors. Looking at the numbers, it clearly shows that Oracle have made significant gains in both raw boatspeed and tacking performance.

Looking at the boat speed polars, you can clearly see how the game has changed from Race 1-2 to Race 8. Oracle is now quicker in all points of sail.

In the early races, the lack of tacking performance of OTUSA was plain for everyone to see. In less than a week, the tables have turned. As you can see below, Oracle now has a much higher speed through the tacks, which leads to gains around the course.

For such a short period of time, those gains are nothing short of impressive. Now if only you could make those sort of gains in a week in a moth …

Update:At the end of the cup, Oracle were simply smashing ETNZ. Looking at the speed over ground polar it is almost a no-contest when it comes to boat speed. Dean Barker himself said, “We went from being a minute ahead on the upwinds to being a minute behind.”
