This is a trip I did a few months ago now, from Makara to Owhiro Bay on the Wellington coastline. I’ve only done the trip once before, and the trip is tide dependent and requires meticulous planning, tides can run in excess of five knots along this coastline, so it’s important to have them working in your favour. The tidal flow gave us a big push, I’d guess taking at least an hour off the trip.
I’ve also got a Cook strait crossing one I will dig up.
Fantastic, thanks for posting! :D
