Tuning Tips by Tiesda You
The Serenity is quite a special board to tune because I designed it from the ground up to be as simple as possible to use - that means that there is very little tuning options! It's a plug and play toy where you just get on and go.
With simplicity as one of it's fundamentals, the only tuning option left is your fin choice, your mast track position and what sail you want to put on. Of course, your sail will have a vast tuning range too.
With the deep Tuttle box system, there is only one fin position possible. However, there is a wide variety of Tuttle head fins available on the market that allows you to tune the board to match your needs perfectly, and this fin choice is probably the most important tuning consideration of all.
The supplied fin is the largest size you'd want to use on the Serenity. It's 70cm deep, very stiff and very powerful. We've chosen to supply you with this fin so that you will experience the most exciting possible lightwind sensation straight out of the box. It's so powerful that in the slightest bit of wind, the board rails up and just drives forward, leaving the board's slender shape to keep you a float and cut through the water in eerie silence. It's like magic and on a personal note, it's the board design I'm second-most-proud-of since I first started shaping boards at the age of fifteen!
The supplied 70cm is very stiff - this adds more stability and it makes the board more steady. I know that some of our riders like Remi Vila like to fit a R19 Race NR 70cm fin because it has more flex. Remi likes the sensation of feeling the fin breathe, allowing him to coax more speed and power into the board and 'foiling over'. It's all quite personal so there really is no perfect formula. The rule of thumb: experiment and choose whatever suits you best.
The other fin we supply with the board is the Shallow 41cm. This would be pretty much the smallest size you can use in the Serenity before the board starts to behave in a very strange way. I've tried to use a 34cm slalom fin just to see what would happen and the board refused to even go forwards.
You'll see that this 41cm shallow fin is actually surprisingly well adapted to the Serenity, especially in slightly stronger wind conditions. The board feels more like it's gliding forwards than powering forwards through the fin. It also helps the board's manoeuvrability.
In between these two extremes, there is a wide range of other fins on the market that will allow you to find just the right balance between power, glide and manoeuvrability for your personal taste. There's been a few forum threads discussing ideal Serenity fins so checking up there would be a good start too.
Mast Track Position
For the mast track position, the recommended setting is simply the centre. In more windy conditions, we can inch the mast track position forwards to allow the sail to rake itself further back too. This position allows the mast track pressure to hold the nose of the board down lower, increasing the waterline length that gives you more upwind grip and a faster, steadier glide through the water.
There's a wide variety of sails that will work on the Serenity. In fact, pretty much all sails work on the Serenity. The hull is so slippery in lightwinds that the sail will be subjected to quite a bit of apparent wind, bringing more power into the sail which in turn generates more speed and therefore even more apparent wind. This loop is how the Serenity achieves such a fun, fast and gliding ride in such lightwinds.
So the choice of sail depends more on what you want rather than what you need. If you want to save some cash, just use any sail that you already have - your largest wave sail, your 8.0m freeride sail, a twin cam sail or your full blown 10m Formula sail. They're all great for the board:
A large wavesail:
it's light, it's manoeuvrable and fun. You'll still get plenty of gliding sensation but won't have any trouble uphauling or flicking the sail around. Probably the less suitable of all options though.
A freeride or twin cam sail:
lots more speed and glide, especially if there are camber inducers. These cambers hold the sail's shape in place so the whole package becomes that much more efficient. Still not heavy, so still lots of fun. Probably the best all-round choice.
A large race sail:
this will give you the most performance and the most speed. The deep shape of the sail will generate lots of power but the downside is that you'll be dealing with a large, heavy sail that at the end of the day, may not give you that much more performance. If you're in a racing situation, it's definitely the way to go.
What would be the best sail for the Serenity? Without a doubt, it would be either a raceboard class sail or the Severne Glide. These sail designs are the perfect match for the board because they are specifically shaped to generate lots of power at lower speeds. If you want to find a rig to go with the board, it's definitely worthwhile to check our one of these options.
I guess this final comment should go under sail choice too, but the Serenity is also a great board without a sail at all. In zero wind, get hold of a kayak paddle, sit on the deck, paddle away and enjoy a cruisey ride with the family anytime.
