Which rudders for which boat?

I thought 5.5 and 6.0 rudder system was the same. 5.0 has a skeg so it would use a smaller blade!When you say stalling was it cavatating (rudder)so there was no steerage or what was happening.And your pretty brave to open up with Mystere rudder issues.

Hi David -

Those do indeed look like the 4.3 rudders. Please measure them (approx length, width and thickness) and e-mail me how much you want at williamsjohn at cox dot net.

Thanks!

Hi John,

For general interest I'll post the numbers. The small blades are 33 inches long and 8" at the widest. The big ones are 37.5" long and 10 wide. Since all Mysteres use the same castings the thickness is moot. I'd like to get $5000 for the pair but I'd take less.

The little blades were useless on the 5.0XL. Under any load at all you could see them "aspirate"...air bubbles traveled down the leading edge and flowed off about a foot underwater. As soon as the boat heats up with slight weather helm the rudders slam sideways within the air pocket, the boat stops and rounds up, and it takes several seconds for clean water to "reattach" to the blades. By now you're in irons and really pissed off. I repeated this event about 50 times. If I sailed gently like a little girl it would be OK but the Opti prams would pass me. Now with the BIG blades this boat is solid as a rock and loves big air and rough water.

Just don't rake the mast...but that's a different topic.

I was just lookin around and I found this! Nice.

As far as those rudders go they are usless on anything but a 4.3. Stevie had those on his M5.0 and after he put the larger sail plan on the boat they really got bad. He put the 6.0 blades on and loved it.

As a subsequent owner of Rob Daniel's M6.0 #310, I took ownership of a M6.0 with an "extra" set of rudder blades. They were shaped like the curvey blades that you exhibited here, but were larger than yours.

When you said...

I had to object because of the fact that my two sets of blades were very different in thickness. The curvey ones are thinner than the larger ones. The curvey ones fit into a set of Hobie 16 castings, (with a little modifications to the perimeter sizing), while the standard 6.0 castings and blades were thicker.

I should have also mentioned that my curvey ones are longer than the 4.3 model rudders shown earlier. They appear to share a similar perimiterical shape with the 4.3 rudders, but are of a larger scale.

I think I found out your problem as to why the wider rudder is thicker. It has a hammer attached to it. That seems to be something that Bob had a hand in.

Be careful in this forum. Mutiny might be afoot.

Craig want me to put a good word in for you about a Supercat forum !

You better wait till I figure out my long term plans...

Gary are the thinner rudders from a m5.0 in the photo?.

I don't know what they came from. Some Mystere, I suppose.

GARY

I have three sets of rudders, the little ones in my first photo, the larger set from a 6.0, and a nearly identical pair from a 5.5. All 6 blades have the same thickness for the white plastic hole insert. The insert is about 1 mm thicker than the blades for 2 of the sets. However, the 5.5 blades have a thicker gel coat that makes them impossible to get into the castings without some sanding (which I haven't done yet). Since the 6.0 blades fit, I use them.

I am dating myself and my boat to suggest that the rudder on the left came from a Mystere "S". If the pair is still available (for a little less that $5K!) I would be interested.

mystereS...Please check your PM at this site.

I guess the next question is, what's a Mystere "S"?

Is the "S", the start of the 5.5 line. Stands for "Sexy" as hell, Yeah baby Yeah!

From what I can tell from my sales brochure the Mystre "S" is an evolution of the original Mystere. They added 2 feet to the original mast to take it to 28 feet, added double trapeze etc. The boat is just shy of 18 feet and is a 7/8 scale Tornodo (sp?). I bought mine new in 1983 which dates both the boat and the skipper!!

The 5.5 line was the next interation if I am not mistaken. The two boats have litte in common other than two hulls and the rudders.

Thank's "S". Didn't even know Mystere was building boats that long.

I might add that I recall a regatta at our local club in Toronto where the Mystere folks showed up with a factory boat and the designer. They smoked the entire field including several Tornados (in an identical boat we languished mid field!!). I was humbled by the skills of the skipper/designer who it turns out was some Olympic class sailor from England - wish I could remember his name.
