capnsensible;4930445Was going to say I never have had a problem with IALA B as its used all over the Windies said:
it may have changed as it's been a few years since i was out there but there were then a number of Islands who used IALA A. Saba I recall was one of them. Easy to forget where you were !!
I remember delivering a yacht up the cape fear river to Wilmington. Virtually no buoys. It was all lit transits ! probably a good method of navigating the river provided you had a chart of course......
Possibly the only cardinal mark in North American waters is a N cardinal at the north end of Fighting Island in the Detroit River where the two channels either side of the island meet (42°14'.9N, 83°07'.0W). It is on the international border between USA and Canada, so not sure which side it belongs to.
As one American mobo-er passed us he remarked loudly "What the **** is that thing!". He drove over to take a closer look and promptly ran aground.
No there are quite a few.
They do tend to use fixed day marks to mark channels and rivers.
there are still a lot of single lateral marks which can be confusing.
The worst I can think of is the Marks for Seaforth Channel where the ends of the reef are Red and Green.
What is very rare though I do know of a couple is the Isolated Danger Mark.
It would appear there must have been a cheep deal on bifurcation marks which are used all over the place.
