Ah Peter, but East Coast keels ride up with wear !

You might like this one. This is tip no.196 from a book I am reading for making sure you don't bash into the big stuff :-

'Let's look at a merchant ship approaching on a 30 degree angle from our bow.

The formula for closing speed is the square root of the sum of your speed squared and the other vessel's speed squared, minus twice the product of both vessels' speed multiplied by the cosine of the crosing angle.'

I skipped to tip no 197 ............

True...but heeling still works!

Going back to school days, I seem to remember the cosine rule as:

a^2 = b^2 + c^2 - 2.b.c.cos(A)

I think that's the formula your tip uses.

Reminds me of the formula quoted in RYA course booklets a few years ago for the scope of anchor chain to be put out for varying depths. They suggested:

Minimum scope = 12 . (square root of depth)

Trouble was, they forgot to say what units were used. Try it for depths of, say, 4000mm, 4m, and 0.004km.

In later editions they specified depths in metres!
