Make sure that you time it so that you are going through the swellies at slack water, preferably HW as well. It can be done at low water, even LW springs, but it is much more tricky, especially if you haven't done it before. Also, I'd buy the admiralty chart because it shows the straits in a lot more detail than an imray. Watch the change of bouyage, I think it is at caernarfon. With all of the sand banks it could catch you out.
