If wave period was say 15 seconds and the swell 1.5 metres max, I would think it reasonable to cross but I guess you would have to suss out the breakers visually? Shorter wave periods to me indicate chopy seas and a rougher ride, but I guess the breakers would not be as intense cause the volume in each cycle is less. Again you would have to assess maximum wave height?

Joe theres many variable such as primary swell size, secondary swell size, sometimes tertiary swell, swell period, swell direction, tide and obviously wind.

Greater swell periods generally are associated with long traveling ground swells generated from a storm system a long way offshore smaller periods are associated with storms closer to shore normally creating bumpy conditions. A 12 sec swell at 1m will be more powerful than a 6 sec swell at 2m but the 6 sec swell will be lumpier. Hope that makes sense.

Certainly does make lots of sense. I've absolutely enjoyed getting out on those long gentle rolling swells. Add some crosswinds and a short wave interval and you get that terrible washing machine....Those long swells generally create those great breakers that surfers like and that are bad for bar crossings I guess.

Exactly. Long wave period equals a lot of water in the wave. When the front of the wave meets shallower water it slows down and the back of the wave catches up. Swell then stands up much higher and breaks. Offshore a long period is just slow rolling hills and nice and comfortable, this is the trap, conditions good for fishing but crap on the bar...
Many boats crossed the bar safely that day, but they knew what they were doing.
The trap is also the current direction in the channel. Run in bar looks good so off they go. Then the tide turns and runs out. The bar goes to crap and they have to come back through it. Again knowledge of how to do it enables plenty of people to cross with minimal risk.
There's nothing . . . absolutely nothing . . . half so much worth doing as simply messing around in boats.

Think I have read somewhere there's a bar crossing course you can do at lakes? Know anything about this re-tyred

Yes Tafe in Lakes does do one, but it is only on when they get enough applicants.
I have done the professional one as it is part of my passenger carrying ticket. It is well worth doing. However if time and money makes it hard to get to, then a good study up on the Gippsland Ports site and a few bar crossing videos will help a lot. The issue with Lakes bar compared to many small estuaries is that there is a defined channel that is marked by lead lights. It is very important to understand how it is marked and to stick to the "leads". It is also important to understand the effects a VERY large estuary has on the narrow channel during run in and run out tides.

Check out this site. It has the bar crossing course details and dates.

They also do a radio operators course so you can also sit the exam and "legally" use the VHF marine radio.
