Hi Dave, They are N28.01.197-W082.48.170
Its the fourth island south of the Dunedin causeway. Thats counting the little one with nothing on it, we call it Nipple.
If the weather is going to be cold and windy we may wind up on the first island. Its a bit bigger and gives a bit more protection from the wind. If your intersted email me and I'll give you my ph. #
