Take a look at Easdale RIB Rendezvous - Home
This year's event is a circumnavigation of Jura so your two points of interest are included in the information which is available on the site.
I can understand the recommendations of the marinas but do also take a look at Easdale just north of the Corryvreckan. The harbour is excellent, there are both self catering cottages and B&B accommodation. Some even camp.
Another advantage of Easdale is you can come and chat to us for information on local RIB venues. WE spend a lot of time in the Corryvreckan and yes we do visit distilleries as and when required (Scottish Whisky Association photoshoot of Islay and Jura distilleries Oct 2013 was our last extended visit)
You are of course also welcome to join us at the Easdale RIB Rendezvous 10/11 May 2014.
