If 14 hp goes hull speed with no current, it will also go hull speed with 8 knots of current. The same will be true with 28 hp. If hull speed is 6 (for example), you won't go against the flow no matter what size motor you have. (You won't do better by adding blades to the prop, either.)VidaliA wrote:I... where the currents can reach 8 knots you may want more power. But 14 horses goes hull speed!!.

an experience I had just last week....
during a sail on the Piankatank River (lower Chesapeake Bay).
I was sailing BuscaBrisas up river (right to left below) on a starboard tack beat, towing a dinghy, when I came to the bridge:

It looked pretty close as to whether I would be able to sail through the bridge, but as I neared it, I determined that it was too close for comfort; I didn't think my course was perpendicular enough to the bridge to clear the pilings, especially given the current and extra drag of the Bolger Nymph. I concluded that if I were forced to tack, I likely wouldn't make it through without smacking a very nasty looking concrete piling.
I started the outboard a few boatlengths shy of the bridge and was under the bridge when the wind quickly went from maybe 10 kts to probably 25 kts. The (protected) water to the east of the bridge had had waves of a couple inches but to the west, they were already at least a foot high with lots of whitecaps. As you might have guessed, I was overcanvassed. I motored through and away from the bridge a distance. BuscaBrisas displaces less than 2000# and she has a 5 hp outboard. She was making very slow progress to weather at full throttle, thanks to the wind, current, and the extra drag of the sails which, some might argue, perhaps should've been dropped before attempting the bridge, although had the single cylinder engine failed while exiting the bridge that probably would've been a greater predicament.
I have been tempted to switch to a two hp for the weight savings in it, but in this case, I was glad I had the five. This is just one case where a quick change in conditions at the most inconvenient of times could've easily spelled a bit of a mishap. I was lucky.
I believe that the very same day that I was negotiating the Piankatank bridge, an experienced singlehanded sailor went overboard on the Chesapeake Bay and is presumed dead. http://www.nj.com/news/ledger/index.ssf ... xml&coll=1

my cd 28 has an MD11-which I am told is either 24 or 28 hp-anyway-its way more than enough power and I love it-the only thing I can ad is that the cd 28 seems to be a very good all around boat-earllier this week my daughter and I went out for a few hours in the afternoon-with the boat on a mooring and the wind very light and blowing straight in I used just the mainsail and tacked out through a crowded mooring filed with no problem whatsoever-as a matter of fact-the batteries were on-the sea water intake for the engine was open and the key was in the ignition but a tno time during either sailing on or off the mooring did I have the engine running! In other words-In other words-a cd 28 can be used as a daysailor-a weekender or a long voyage cruiser-all with equal success! how many boats can you do that with? how often do you see someone in a 28 ft boat sail to a beach drop anchor under sail and pull up the anchor and sail away without using the motor? all I an say is nice boat!!
