I reviewed these notes in August 2022. They tell me that they are just breaking ground for a new Marina amenities building here so next summer it should be really posh.

I reviewed these notes at the end of June 2021. They are still cheaper than Rhu and the facilities are very good. Expect to see an increase in the berthing here in the next couple of years as they are optimistic that they can start expanding into the commercial basin to seawards of them this coming winter
Update Spring 2019

These notes were reviewed in May 2019. All is well; they expand every year and hope for new building in the next couple of years. New charts have been uploaded.

I reviewed these notes in April 2017 having been in there last year. Since then they have handed over ownership but have retained the original staff. They intend increasing the number of berths to occupy D walkway below the lifting out bay. Prices have gone up this year but still cheaper than Rhu across the other side.

Update summer 2016

We have now spent a few nights in this marina and it is no longer just an almanac stub. The facilities are fine here and, for the scale of the operation surprisingly cheap. There is a 12 year plan for expansion on the shore; apartments, des res etc but it is believed that the marina itself has just about as many berths as it can hold.
