G'day Wilky and Paddlewise,
					Thanks for the information about the wave rider. The BOM internet
forecasts are beautifully presented and easy to understand but I'm wondering
how they use the information from the wave rider - is it just for measuring
swell? A sample extract from the forecast for the Tasmanian NW coast says:
"Seas 3 to 5 metres. Southwesterly swell rising to 2 to 3 metres". So at
what time between peaks do they stop referring to swell and start referring
to waves? Anyway its clear this would not be a day for going out - not me at
least !!

All the best, PeterO
