Mysterious Floating Object

A fairly fine day mostly of sunshine but windy and some showers throughout the day.

A really busy day again at work with more workshops for the bairns and been a real increase in tourist numbers again :) Time to step up a gear and get back into swing for the busy summer coming :)
Popped along my sister after my chores were done and took my niece Elise out for a run in the car. Went went down to Sumburgh for a look and I spotted one Puffin :) Shame he was too far away to photograph and he was flying too, I'll check again over the weekend :)

This mysterious floating object has been in Lerwick harbour all week. I'm not sure what it is but might be measuring the depth of the harbour or such like. I'll maybe find out sometime before it heads away again :)
