We just took part in an event from N.I. to the Menai Straits in the Bangor Challenger (RB4 etc). The "Irish Sea Challenge" left Carrickfergus, N.I. last Thursday and went via Port St Mary to Bangor Wales, then on to Liverpool, Douglas and Portpatrick, finishing yesterday (Sunday 5th august) back in Bangor, N.I. We in the Challenger left them at Bangor and went through the straits on Friday midday approaching high tide, then on down the Welsh coast to the Bristol Channel and back up to Holyhead, eventually rejoining the fleet in Douglas (via Howth). The run through the straits was most beautiful and "picture-scue". It is wee buns in a rib in these (good) conditions. The port & starboard marks are easily followed as long as you are aware of the change from port-left to port-right just around Dinorwick; yuo should take your Macmillan Almanack with you. I would recommend stopping off at Caernarvon and Beaumaris or Bangor.
