Having chosen different tacks . . . . . . . .

Very, very lazy day today, lying about at the pool, despite still having a hire car sitting doing nothing.  We will use it tonight to go to a Thai restaurant, foregoing the delights of half board dinner.
So, whilst basking in the sun, SHMBO noticed about a dozen identical sails passing the end of our sea inlet.  Shot off down the road & path to the headland but by the time I got there they had all made the windward mark and set of back downwind, spinnakers flying.  All except one who had managed to sail over their's and got somewhat stuffed by all the others.  The above is a crop from a much larger snap, as in extras, hence the fuzzy nature.   I don't recognise the class.  Do you?
Stuck in a couple of silly crops, just for fun.  ;-)
