As you may guess, at this point in time, AYRS is postponing or cancelling all activities that may bring groups of people together. We are reviewing this on a month by month basis.

The SW UK Area meeting is therefore cancelled (but see below), and the Norfolk sailing meeting (Broad Horizons 2020) is postponed at least until mid-late June.

It is possible that some meetings may be replaced by online video conferences (by Skype or similar). For further details please see the Forum where these things will be announced.

New Years Resolutions

AYRS relies on the members writing about their experiments and ideas so YOUR No.1 Resolution is to write and let us know what you are doing. Then we can publish it in Catalyst which helps you get your monies worth!

You can also do your bit by encouraging other members to use the forum which means members can get something in between issues of Catalyst.

As is now the custom at our Winter Meeting, members arrived just after noon for a 12.30 pm start. There were seven members and four of their wives present. Three apologies from absence were received from Roy Anderson, Steve McKenna and Colin Weir. After a short introduction, a Buffet Lunch was served which was enjoyed by everyone (thanks Col). Amply fed and watered, the Ladies retired to the conservatory leaving the Gents in the lounge to have their ‘official’ meeting.
