Great little island is Gigha and great for a small boat adventure. The 9m ribs probably shoot past it in 3 minutes!
Don't want to seem Mr Moany - but there has to be better ways to navigate than a OS Map which is only accurate above MHWS and a 300 year old chart. More than just sand banks will have changed. There could be new underwater obstructions (wrecks, newly discovered rocks etc), there could be reasons not to anchor (under water cables), there could be new jetties etc which may not always be marked on an OS Map. A SIB hardly needs a jetty but in terms of passage planning a Jetty is an escape route.
Not to mention any navigational marks.
Plus an OS Map will usually highlight certain land objects visible from the sea that can be used for transits etc. The OS Map gives you them all and you may not know if you should be able to see a church from the sea etc.
You can get free electronic access to charts via Navionics website.
Do come back again if you want to see some of the best sandy beaches in Scotland.......
The Scottish Maffia will be on to you. You need to remember the official line is that it rains all the time and is full of midges. Keep showing all these nice scenes and the "Public from Englandshire" will arrive...
