Mark is referring the the big motor on Frank's boat. If you keep responding to this thread without understanding the history, you will probably embarrass yourself. It really is an "entertainment only" thread (even if Frank didn't intend it to be.)
Steve knows well, owing to his Ventura home port. The standing joke about my race trainer Murrelet goes as follows. Which one of the crew lifts that big outboard from the water? The answer of course is that it takes more than one person.
Near Ventura, Costa Mesa, in particular, or north of there, Monterey perhaps, but in anycase near where the Santa Cruise 52 was conceived, they invented modern surfing. The application of fiberglass to boat design began with surf boards and in short time it was known that you need your foils aft as well as the weight of the rider. The same is true with sailboats that surf - which when doing so for more than a few minutes are said to plane.
The TP52s are objectionable to most real sailors on the West Coast because they attempt to take what is planning sailboat design and apply the failed fixed bulb fin experiment to them.
The TP52s, like the 12 meters, are little more than amusement rides. Those on our cruise liners will find them an attractive shore attraction, but they do not really fly in the modern sense and a novice should not put such an experience on his or her sailing resume, because it marks them as not only novice but also a fool. They lumber at mostly hull speed, and this after millions spent on them.
The lead mine at the end of the TP52 is the wrong place for the weight and in addition it provides only one purpose, where everything on a sail boat should have at least two. To the credit of the TP52 designers they are required to have an engine auxiliary but unfortunately and most assuredly from a hull design standpoint the motor must be an inboard, and this compromizes them greatly.
Every basic design book will demonstrate that the inboard engine dictates the kind of buttocks. There has to be lift in the buttocks to provide an arse hole for the shaft and then there has to be room for the prop. In every way the design is literally screwed.
My vessel has the weight were it belongs for a modern design and it provides more than one purpose -auxiliary power and stability providing ballast.
The power is auxiliary because these race trainers can not store enough fuel for passage making. Compare with the very real efforts of designers to keep the iron genny auxiliary by purposefully mounting motors that rarely can get the sailboat to hull speed. The idea there is that if the wind is blowing enough to carry the boat to hull speed under sail then the owner should be sailing not motoring. Hence the designer has engineered for the human rather than eliminating compromise. He wants the owner to sail and knows that for speed reasons that will happen at least sometimes if the motor is wimpy.
I tell you these design secrets to save young US potentials. We intend to be champions and not the chumps that think TP52s cool.
