Only thing to say is make sure you have EVERYTHING you need on the boat out the car before you go to park - it's an awfy long walk back to the slip..... (don't ask me how I know!
)
Other option (as you are coming from the North) Is Linnhe Marine. On the A828 just before the climb up to the Castle Stalker viewpoint assuming you are driving south)
Not a huge difference in water distance to the Sound if you go down the west side of Lismore, and what little extra in fuel is offset by the cheaper launch fee!
