Hi Dennis,We sailed for 3 or 4 years on the Mississippi River at Dubuque, first with our Merit 22 with a 4 hp outboard and later with our Victoria 26 with a 15 hp inboard. Now we're at Lake Pepin (which is also the Mississippi River but a heck of a lot wider). In the spring one year with high water and strong current, my 4 hp, at full throttle, barely got me back upstream, but, except for spring flood season, the current is no real problem. In fact, it makes you a better sailor. True there is the occasional barge, but there is always room to avoid them and, since you sail at Saylorville, I know you're used to power boats and jet skis. No different on the river.The biggest problem with the Mississippi is flukey wind which can change direction 90 degrees or more in a couple seconds (due to the topography, especially with the high bluffs around Dubuque) or can die a quick and sudden death (not good if a towboat is bearing down on you)So....rig a preventer and/or keep a close eye on the boom, be ready to start the motor on short notice, and keep a close eye on traffic. River sailing is a blast, especially locking through. A couple more things to remember. With a 2 kt. current your speed over the bottom going downstream can easily approach 7 kts in your boat, but coming back up will only be about 3 kts. at best, so keep in mind it will take you twice as long to get back as it took to get wherever you're going (unless you're going upstream of course then the reverse is true)Stay between the bouys and you'll be in the main channel and have at least 8 feet of water, stray outside them and there are wing dams, submerged trees, logs, and a whole lot of other stuff that can snag your prop, rudder or keel. I learned this the hard way.
