Ski, sail, sauna, and swim

A fun day, starting with emergency skiing the quickly disappearing snow on my local hill at 6am, continued with sailing to Suomenlinna on Markus’ boat - thanks! From then on the company picnic day was just starting Lot more fun followed, e.g., a sauna and swim in the Suomenlinna boat harbor. 

Now I just need to go collect my car from the starting point Did I mention interesting discussions and first time seeing new colleagues ? And, why no meetings today? Because it is the Independence Day in Sweden Congrats!

On the sailing we also went past the Finnish snake island (Käärmesaari).

And in the sauna, we had an interesting discussion about the rocks for the stove. They obviously have to be changed regularly in order to clean up the debris from cracking stones. But are the uncracked stones ok, or do they lose their ability to function well also? The Saunologia blog article outlines nicely the cracking behavior of different types of rocks (see here). And this Yle article mentions that aging stone can become porous and lose its heat retaining capacity, but without describing the details. And Norwegian researchers have looked at the physics of sauna's heat absorption on wood here, but not dealt with the stones.

I have been unable to find any research results on other aspects of aging-related performance degredation in the sauna stove rocks.... does anyone know?

Information about guest boat harbor in Suomenlinna can be found here. And it is served by Cafe Bar Valimo few meters away, hosting both a restaurant and the sauna. Much recommended!
