After years of sailing multi hulls I am switching to a monohull. On the back of my Hunter 23 I have a Honda 8hp 4 stroke. I do not have a knot meter but after sailing in 15-20 kts I could have sworn that we were going faster with the sails up rather than just motoring. I am I right or wrong? Thanks for the replies Tony

could be...
I have found that my 33 is faster undersail than with motor and my engine is a 15 hp yanmar inboard. So, other than getting in and out of the marina, sails are it for me. Enjoy!

Don't have a clew!
Hull speed for the h23 is 5.9 kts. My Nissan 5 hp pushes my boat about 5.7 all out. It would seem that your 8 hp would easily push the boat to hull speed. I'm told that when the boat is "surfing" down the backside of a big wave you exceed hull speed, but I haven't had this happen on my lake yet! LOL

Oh yes!
The H23 sails faster than it motors. With an 8 hp outboard, I get 5.5 kts at half throttle. Running the engine harder doesn't get much more speed in flat water. However, under full sail in about 15 kts of wind, I have seen 6.4 kts on a close reach and 8.6 kts on a broad reach (at which point the boat was planing). Others in this forum have reported boatspeeds in excess of 10 kts. The boat is entirely capable of exceeding the theoretical hull speed under sail. Have fun! Peter H23 "Raven"

YEs!
My Dad and myself have our hunter 23 on a 3 mile long lake in Northeastern Pa, currently we have a 4.5hp 2 stroke Johnson. One day we started out with a good wind and were moving nicely, we traveled to the other end of the lake in 90min. With little light and even lighter wind for the journey back, we decided to motor, it took 2 and 1/2 hours. sailing is deffinatly faster

Tony: This season I had the boat up to 5.7 knots under jib and main on a 10-15 knot day. Hull speed assuming a displacement hull is 5.9 knots. However, the H23 does not have a displacement hull but rather a semi-displacement hull. With a 9.9 hp 2-stroke long shaft at 50% throttle, I had a GPS speed over ground of 6.5 knots into a 25 knot headwind, so I guestimate a through water speed of 8.5 knots after accounting for surface current. I know that the boat was planing because we had overtaken the bow wave and we had the traditional two-wave wake of a powerboat. With a beefed up engine mount next season and the engine broken in, I am curious to see our performance at 100% throttle! Anyone with experience waterskiing behind a H23?

My 9.9 Tohatsu moves my '86 H23 6.2kts, and sails can do the same. In combination I get 7.2kts , but who's into this for speed? To me the term "fast sailboat" is an oxymoron, for sensation of speed is relative. Sailing at 4kts seems faster than motoring at 4kts, and motoring is so damned dull. I sail not so much for destination, but anticipation of what may come along the way.

Mark: Ah, this is the usual sort of discussion sailors adore and stinkpotters abhore. Notice that the entire discussion is about a range in speed of about 1.0 knot. Yet on a sunny day with favorable winds, we'll spend time adjusting the topping lift, outhaul, cunningham, sheets, maybe even pull out all the stops just to get another 0.5 knot. But then at 6.0 knots, you're not going anywhere fast so what else is there to do to kill time? Besides riding a header, that it is. Cheers! Kevin.

Speed
All decent sailboats should sail better, faster, more comfortably and more safely under sail. That's why they are called sailboats. As for the H-23 reportedly exceeding hull speed, this is because it is so light it probably planes. The BIG issue comes up when you are dealing with a substantial displacement hull-- as my uncles 1973 C-and-C 35. This boat had a moulded fin keel 6 ft deep and displaced 12,000 lbs. We had it up to 9-1/2 knots-- like two knots OVER hull speed in a fresh quarterly and were pretty much surfing into Branford Cove. For a goof we put the engine on-- got to 10; turned it off. But the bow wave must've been over 5 ft high!!! If you are trying to increase apparent speed in something like a 23, get on a reach with the wind a little aft of the beam. Shift all weight aft to the windward quarter. Hang on. Let's hear what happens. But remember that is darn near planing and sort of 'doesn't count'. The short answer is that for the horsepower and effort expended, the well-sailed sailboat should always be more efficient and ultimately faster under sail. JC 2
