Amazing Sail

That's what she said.

I agreed. That's pretty much the story. The impatient can stop reading now.

For the patient reader, we'll go back in time. Ever since I owned more than 2 sails, I had a mix of different styles and brands. At some point, I came close to have a collection ranging from 5.5 to 7.5 square meters of the same model .. only to discover that the manufacturer had totally changed the character of the sail, but kept the name, when I bought the last missing size. Bummer!

When I started to dabble in speedsurfing, things got worse. The first sail I bought was the sail that had held the top speed on for years: a 2007 KA Koncept 5.8. The fact that the sail was about 5 years old and a real bargain made the purchasing decision easier. Even though the sail was supposedly developed for light weight surfers (which I am certainly not!), I liked it. Over the years, the 5.8 Koncept got larger and smaller speed sail companions - some where gifts (thanks, Dani!), the others were bought used and cheap. They were all decent sails that had a well-established fan base - but they also all rigged and behaved differently, and I can't say I loved any of them.

In stark contrast, my lovely wife approaches windsurfing in a much more orderly way. Once she discovered that (a) freestyle was her thing, and (b) she liked North Idols, she made sure she had the whole quiver: 4.0, 4.2, 4.5, 4.7, and 5.0. I also bought a 5.6, but she never uses that one. So she can use a sail that feels pretty much the same, regardless if it's blowing 18 or 30. Maybe that has something to do with her being so good.

While freestyle is Nina's first love on the water, she also likes slalom and speed on occasion (for example when she can leave tons of guys behind at a Kashy/WET slalom regatta). When it was time to replace my old Koncept 5.8, we ended up buying a "barely" used Loft Racing Blade 5.6 from Boro. I have not yet had a chance to use it, but Nina sailed in both both light and strong wind, and loved it both times. That alone is quite unusual - the other racing and speed sails we sailed usually did not behave well in light conditions if they were great in strong wind, and vice versa. But I had an opportunity to sail a Loft Racing Blade 7.8 last year, when Boro visited, and liked the sail a lot.

We had also bought a used Loft Switchblade 7.8 earlier this year. That's not a full race sail, since it has only 3 cams and a narrower mast sleeve, but it has plenty of low-end power and top-end stability. More importantly, both Nina and I like it a lot (Nina especially if I rig it and then the wind drops, so she does not have to rig it or carry it to the water).

So when our fellow speedsurfer Al from New Jersey reported that he had bought several Loft racing sails from Poland, Nina started talking - "wouldn't it be great if we also had the same sail for speed in all different sizes"? Who am I to disagree? So we placed an order for 3 sails (5.0, 6.3, and 7.0), one mast, and a few more things. That included a couple of mast bases and extensions, since the racing sails need 3 pulleys, and all RDM extensions sold for the "US" 2-pin system have only two pulleys. This ended up being the biggest order for windsurf gear we had ever placed - with a shop in Europe that we had never done business with!

But within less than 2 weeks, everything arrived in perfect shape. Even the weather played along: yesterday was windless but nice to allow for some practice rigging and batten tuning; today, we got perfect wind to try the 7.0.

At first glance, today looked less than perfect. It was rainy and cold (57ºF, 14ºC) in the morning, and the wind meter readings were just around 20 mph. That may sound good, but the Duxbury meter tends to read high, since it's sitting on a very tall pole that has a much better fetch than a windsurfer in the bay. For my older MS TR-7 race sail, that would have been marginal wind - I would have chosen to rig the 7.8 instead. But the new sail needed to be tested, so out I went. Here are the GPS tracks:
A few things to note:

  • I was planing the entire time until the wind dropped near the end of the session (when averages dropped to 17 mph, then 15).
  • I planed through a whole bunch of jibes. That's amazing since I often have problems when jibing cambered sails.
  • At the end, I switched gear with Nina, who had a total blast on the slalom gear (117 l board, 7.0 sail) in 15 mph wind. I had somewhat less fun sailing her 90 l board / 5.0 m sail back to shore. The board plaid submarine most of the time - U-Boot windsurfing is not so much fun.
I was quite amazed how much power I had in the relatively light wind. At the same time, this was "easy power" - the sail never felt heavy. Nina said it felt "like a freestyle sail", and I have to agree. On land, the sail feels a lot heavier than a freestyle sail - on the water, not so. Even the slogging, which can be a pain on some race sails, was nice and easy. The wind was too weak to test top end stability, with gusts never exceeding 24 mph, but the "locked-in" feeling was superb - substantially better than in the Switchblade 7.8, which does already feel very stable. My 2-second top speed today was 33 mph- that's 13 mph faster than the average wind speed, and 9 mph faster than the strongest gusts during the session, quite decent by my standards. I can't wait to see how the sail does in strong wind and on my speed board!
