Nope, no Coral
. Just Rock. Pete is very correct in his statement of "peppered" around. You really have to study charts
as you can be sailing in clear blue sea, miles from land, in 200ft of water
or more and a rock will be just under the surface somewhere, ready and waiting. Of course, like all countries, not all NZ is like that. The difference form most countries, is that NZ is hugely variant in geography in a very short distance. The NZ coastline ranges from continental upthrust/down thrust, to alluvial/silt to volcanic to sunken mountain chains to glacial in only a few miles of each event and each event being millions of years apart and in the making. We have live Volcanoes and extinct volcanoes and in the case of many North Island areas, many "hope the heck they are extinct" volcanoes. The country is some1000miles long and 80 across. There is one hr difference in the time of Sunrise/set, between the bottom and top of the country. 98% of the population live within a short distance from the sea. The sea temperture varies all the way around the country, due to currents coming from different parts
of oceans and colliding with the land mass at differing locations.
In Fiordland, the mountians have share verticle faces that drop thousands of feet straight down. Carved by huge ancient glaciers. It is impossible to anchor
, even with the boat right against the rock face. In the Marlborough sounds were Pete and I hail, we have mountains that are sinking beneath the sea. We sail in deep water
in sunken valleys of 100-300ft deep and the infamouse Cook straightthat pluges to 8000ft. Just 30Nm away is some of the shallowest water you can find. The Farewell spit area. You can sail for miles and miles with only 6-10ft under you. The country varies so greatly.
