From Poole RYC:
Sadly our Longham venue has also been hit by the dreaded weed and is not currently sailable. We will be looking to rerun the event later in the year when, hopefully, the weed subsides and we will keep the MYA and skippers informed of any future arrangements.
Unfortunately this means that the Canada cup for Sunday 21st July has to be postponed.
Any rearranged date will be posted in the racing locker & the marblehead class website.
