I assume that you will launch by slipping her on her trailer. As well as Balmaha, you can slip at Balloch, Millarochy, and Ardlui. Balmaha, Millarochy, and Ardlui are Ã¢â‚¬ËœbeachÃ¢â‚¬â„¢ type slips whilst Balloch has two very good concrete slips. By road, Balloch is the closest to you and the Clyde.
You will have to register for free, though the plates and numbers will cost you Ã‚Â£5. The Ã¢â‚¬ËœGuide to NavigationÃ¢â‚¬â„¢ at Ã‚Â£5 is worthwhile.
You will need to have a lifejacket for each person on board.
The south end of the loch with islands and anchorages is the better for cruising, though you are still in the lowlands there rather than the highlands so shallower (20 M ) water and less scenery.
I assume that you sleep/eat aboard and anchor.
You will enjoy Loch Lomond Ã¢â‚¬â€œ better sailing though less public access to shore than Windermere.
