Hanse 388 Real-Life Performance

With a few hundred million more speed and wind data points in the database, here’s some fresh sailing performance data, and some humble guesses as to what it all means.

GPS Precision

Our Hanse 388 has three different GPS devices. A couple of days ago, when I was sorting through the position data, I came across some interesting glitches.

Calibrating Heading

Last week, during my fun solo sail from Finland to Ă…land and back, I had some issues with engaging the autopilot. Regular commentator and Hanse 385 owner Stuart chimed in (thank you!), and suggested I should check the calibration. So I did!

Hanse 388 Performance 2.0

Last year I wrote a post summing up our first season sailing performance. Now, a couple of months into our second season, I think it’s clear that we’ve already found a better gear! In this post, I’ll share some data from a two-day solo sail I did this week.

Wind Polars

Sailboat polar diagrams usually tell us what the boatspeed will be, based on wind speed and angle. I thought it would be nice to flip it the other way: if we want to achieve at least, let’s say, three knots of boatspeed, what kind of wind will we need to achieve that?

Hanse 388 Speed and Polars

So, how fast does our Hanse 388 go? This summer, we gathered over twenty million data points to compare our sailing speeds with what HanseYachts’ marketing material had promised. Here are the results.

A Digital Logbook

Since I was about eight years old, one of my hobbies has been to code, to make computer programs. I love the creative process, and also the off chance of finding some new ways of piecing old puzzles together. This post is about my small sailing logbook coding project.

A Community of Sailing Blogs

There’s a lot of people actively sailing (or dreaming about it as we do!) and at the same time publishing blogs and YouTube videos about their adventures. Here’s my humble attempt to bring this community together, with the help of some computer wizardry and magic.
