Some further feedback on comments
Good video to promote the even, last weekend was superb at Easdale. Mike, I am happy to do your advertising for you. I will get the office to check if you are on the accommodation database.
For those seeking accommodation Mike has a number of large static caravanbs, all good quality. The setting is superb with the caravans right on the water's edge. Mooring, pontoon and RIB friendly. Whilst on the Isle of Luing you launch at the Cuan ferry. Some of the ferrymen come to ERR and will assist with launching/trailer storage etc. Many from ERR stay here as it is very convenient just 5 mins away by sea. The same can be said for Cullipool on Luing.
Size of RIB for the event - Many come and have smaller RIBs circa 4m. I have always threatened if the weather was good I would do the event in the wife's RIB - a 3.4m Humber with a 15HP. Never happened yet and Oronsay is a bit of a haul. Garvellachs yes but once you head past these islands the seas can be lumpy.
