[QUOTE=sailcruiser;1585082]A64pilot, honestly the Great Lakes
can be some of the hardest sailing out there. If wind
kicks to 15+knots you are looking at 4-6' waves with a 2 second interval. You don't clear 1 before hit by the next. They bounce and return off break walls then you have 6' waves from 2 or more directions. I was out in 6-8' waves one time and it was horrible. Ocean sailing you can ride up and down the waves with a much longer period between them. Here they'll beat you to death in a hurry. Lake Michigan can have 12-15' quite regularly with I believe a record
of close to 23' a few years back. Late fall is when it's usually the worst.
It is amazing that no matter where you travel, people will say there are spots with the worst weather
and conditions. From experience I can tell you that the worst conditions you will ever see can be ANYWHERE you happen to find yourself at the wrong place at the wrong time.
The worst conditions you will ever find will be those greater than the last you experienced.
Using shipwrecks as an analogy for the OP's question also does little justice. On ships, we don't have the luxury of waiting out good weather
windows and timetables must be met as berthing times, tugs, dock
thugs, trucks, logistics, etc. are all bought and paid for on a timetable.
Telling someone to wait for more experience does little justice as there is no better way to get experience then get out there and a 70 mile journey is nothing if the OP gives himself enough time to enjoy the trip and wait out any weather if it shows up. Problems normally happen with time schedules, not lack of experience. Just be prudent and patient.
