Wind against tide!

[BrendanS]

Run off from the Guiness factory causes the waves to get a bit tiddly and fall over themselves

I thought you were in NZ. If I were going to cross the atlantic I wouldn't start from the antipodes.

Yes it would be a long haul! I am in NZ but my client is not from NZ. If I have what you were referring to correct, the South Coast I was referring to was the S Coast of England - the boat is destined for the other side of the Atlantic from there.

Any surfer will tell you that an offshore wind running against a big swell is ideal: the wind nicely sculpts the incoming waves, building up steeper hollow faces, making it more likely that the wave will break, and delaying the break. An onshore wind flattens the waves, and does the exact opposite, tending to smooth the sea.

The same applies to wind against tide situations - except here we curse the conditions rather than welcoming them!

(Unless you're sailing a planing dinghy, in which case that sort of lumpy sea gives an exhilarating ride.)

Re: Some sums answered:

I cant comment on the first - but a 7 second wave period? If you were to assume sailing into such waves the effective period would be down to 1 second or so. Empirically I haven't observed such a short period...
