Anyone active on the West Coast of Scotland may find these charts interesting. They are highly detailed charts from a private survey of some of the more interesting anchorages and passages on the West Coast. The level of detail is phenomenal in comparison to the admiralty charts and the surveys much more up to date. I have just purchased a disc of the charts and at £10.99 I reckon it is good value.
The charts come in a number of formats on the disc and work fine with the memory map software I am using. You can also view them with Google Earth.
Well worth a look.
