The blue water colour is created by a dye that is added to the water to help prevent excessive weed growth.
It seems to work well enough and looks good too as the props churn up the water 👍

Attended the Bring and Buy today at Southport MBC. My first visit there, and definitely not my last, albeit that the journey time is a shade over 2 hours from betwixt York and Knaresborough.
Thoroughly enjoyed the B&B, the chat and the setting, but can't quite get over that true blue water. Sorry Kevin !😉

We went there today for a lovely sail in the sun with Rapier 1 and a Vector 80.

Would love to be there!

Local weather forecast for next (and this) weekend is good (!) so it should be a nice day to visit the Southport Club lake 👍
