I looked at a charter for this month but other plans came up. There are some options with Garmin or some other electronic means for maps with a guide book and paper harts for backup.
I was under the impression wind is light in May. I would still like to hear about your trip in May.
Average should be 6-7kts so I imagine we’ll get some 12kts hours and some no kts hours. The coromuel winds will hopefully be blowing late afternoons so I’m planning most routes (hence the chart search) for then.
