Thanks for sparing me a search for this
When dealing with waves, you have to take into account the hull design, length of the boat, and many aspects of the waves you're likely to encounter. My 17' tin can tiller with a 50 hp on tha back could handle much worse conditions than my 22' bass boat. When I fished tournaments, and knew there would be 6' rollers on Erie or Ontario, I'd take my 18' aluminum Xpress, not the 22' Bullet. Sounds backwards, but each hull reacts differently. Now, you heard me right, 6' waves. Those waves might have a length of 25' or more. Those are no big deal, if you know how to ride them. Going in the same direction is often the most difficult. Paralleling them isn't really an option. A hot foot throttle makes it a little easier using bursts of power to keep the bow elevated so you don't spear waves. It also allows you to keep both hands on the wheel. A tiller offers the same benefits, combining the steering and throttle. I've been caught in some pretty dicey weather, but overall I think big, long rollers lull you into feeling safe, but they take even more skill.
This day weather kicked up out of nowhere. We were less than 10 miles from the launch, in the big lake. Coming back to the launch, the wind was to our backs, and we were flying over the little chop. It only took around 30 mins for that to escalate into nasty 5-6' white caps. We were trailered by then though.
It can really expedite things, for sure! On Lake Ontario, you start to see white foam on the crests of chop, and you probably have around hour before things escalate. On Erie or Oneida you have around 15 mins.
