Joe Posted February 7, 2003 Posted February 7, 2003 I am putting the final touches and last coat of paint (weather permitting) on my CS 17 this week. With a prayer in my heart, I drilled the mast hole in the 7/8 " thick mahagony center thwart, with five coats of spar varnish, yesterday. The diety must have been in an exceptionally good mood, as I nailed the position dead on. I have always thought the CS 17 could serve as a displacement picnic boat as well as a sailboat, and I plan on using it as such. I have a long shaft Yamaha 8 which I planned on using on it. The more I think about it, the more I believe this to be gross overkill. I am considering buying a Nissan 3.3 long shaft instead. I do want the motor to push the boat at hull speed with two adults aboard, at a moderate throttle setting. Anyone out there have an opinion on this option? I'm sure Graham has long ago done the math, so his thoughts would be welcome also. Quote
Gordy Hill Posted February 7, 2003 Posted February 7, 2003 Joe, I have gotten along for over five years with oars, however, I've been thinking of a motor. Most of the guys I sail with use a Honda 2hp 4-stroke on their Sea Pearls. The Seapearl is narrower, but longer (21ft) and weighs much more than my CS17. You probably won't get hull speed, but you rarely get hull speed when sailing. I think you'd like the dependability, quiet, and smoothness. Also, instead of a long shaft I think I'd prefer a smaller short shaft with the pull-up mount. If you followed the plans, (I didn't) the motor will fit in the lazarette. Gordy Quote
Brent Posted February 10, 2003 Posted February 10, 2003 A buddy has a Honda fourstroke 5 HP that pushes his Capri 22 (2100 lbs) with amazing ease. The boat does not plane of course, but gets close to hull speed easily. I am thinking that would be lots of HP for a CS 17 or 20. The motor is amazingly smooth and quiet. A significant concern to me is weight. The mass of these four stroke motors goes up fast, I think the 2 hp is about 27 lbs, the 5 hp about 60, and the 9.9 over 100 hp. The boat will SAIL best with less weight on the stern. The 2 hp has a advantage simply because it can be stored forward in the boat, and hung on the stern when needed. I measured the transom on my CS and came to the conclusion that a long shaft motor could be mounted higher away from the water and get better submersion when running. I find I frequently encounter situations with motor running and sails up, causing the boat to heel. With the boat heeled there is a chance of loosing cooling water flow to one of these expensive motors - Bummer. Hey, there is another advantage to the 2 HP which I think is air cooled. Quote
Gordy Hill Posted February 10, 2003 Posted February 10, 2003 Brent, When sailing, and the boat is heeling,... TURN.....THE.....MOTOR....OFF! Ok, I'm a smart a$$. Just couldn't resist. I STILL lean toward the short-shaft with the lifting, spring-loaded mount, but I'm sure either would work. Quote
