Ok Ive added wolf rock as waypoint 20 and created a total of 6 routes 3 there and 3 back (yes i know you can reverse them on the unit)
Ideally I would like to go out via Seven Stones and Back Via Wolf Rock. I have also included the shortest straight line route in case we are running out of time.
Here's a Garmin Data File for anyone with MapSource - At least you should be able to check my waypoints to make sure we don't get shipwrecked anywhere.
All three routes touch the separation scheme to some extent and I've not been too bothered about making sure we are crossing it exactly at right angles. How fussy are they about this - how many degrees away from straight across is allowed when crossing a separation scheme - I'm assuming there is some leeway. If not I will have to add a couple more waypoints in and straighten us up due East/West as we cross it.
