Tuning & Sailing Guides

The following Tuning Guide is intended to provide a very early view of the set-up of the new square top sail. It's entirely provisional and will be updated as we learn more.

Of course, everyone sails in their own way, at different weights and heights and on different waters, so you may find these settings don’t work for you. That’s fine, there’s no ‘right’ answer, and we can all learn from each other as we gain experience. You may also notice some differences from the Hartley Boats Tuning Guide (for example regarding mast rake), and again, it’s all about what works for you.

Any feedback about any aspect of this guide is very welcome!

For those sailing a Mk1, please note that the hull isn't quite as stiff as the Mk2 and Mk2e. The tensions described in this Tuning Guide should not present a problem, but caution should be exercised.
