    Hey gang – Does anyone have any feedback on that FOSS rudder listed on the boat setup page, or with possible alternatives? I’m not so concerned with being class legal, so ideas for other modern rudders to swap in are welcome too.

    Thanks!

    Here is my former Olson (o29 #27) with a water rat (Larry Tuttle) CF custom blade – he did this in the 90’s – well ahead of his time here…

    Mike,

    Here is some info, it’s on facebook unfortunately.

    https://www.facebook.com/groups/olson30/search/?query=foss

    Also follow along with Jason’s posts in the link above, he recently installed the Foss rudder and he has sailed a lot of offshore miles with it. The same rudder was installed by Jiri on a boat that won class in the SHTP. The boat is now in Hawaii. Everyone who has installed the Foss rudder has positive reports. It’s probably slow in very light wind due to the large wetted surface. But offshore and in big breeze it gets great reviews, and if you were offshore with an autopilot it’s much better than the stock rudder. For course racing or inshore racing it might not pay off as much.

    Not a huge facebook fan, but that is a ton of great info right there. Thanks! The price on the Foss rudder is hard to beat, too.

    I don’t disagree on Facebook. Unfortunately the ‘Olson 30 Fans’ Facebook page has almost replaced the forums here completely, which is a big loss in my opinion. There is a lot of great info in these forums and sero white noise to deal with, just discussion of the Olson 30.

    well thanks for continuing to maintain them, and the quick responses

    I am curious – the tuttle rudder and foss rudders are quite different.. i’d be interested to know if the tuttle rudder solves some of the low-wind drag issues without sacrificing the additional control

    What is a “Tuttle Rudder”?

    OK I see. It’s hard to see the rudder in that picture because it’s turned away from the photo. But I do see that now. We don’t have contact info for this person on our suppliers page, I think we should.

    I would also be curious in some feedback on the Larry Tuttle rudder…I believe this is the same rudder pictured above…just gives you a better idea of profile/shape…How would this rudder compare with stock class 030 rudder as well as the Elliptical class rudder?

    I was also told by Foss Foam they built another alternative rudder for the Olson years back…which looks like this…

    The drawing is of the most recent Foss built rudder. Note that there is a mistake in the drawing, the top plane of the rudder should be square to the rudder post. The actual rudders are not like the drawing in this detail.

    What rudder is in the photo in post #5197?

    Photo #5197 is a profile shot of the Olson 29 (#27) Water Rat Larry Tuttle rudder seen in posting #5186
    I’m unclear on the mistake in the rudder pictured in #5199? Pictured here is the rudder used by Jiri and Jason for comparison…

    The drawing in post 5199, I just noticed it is slightly different than the current Foss rudder – however both drawings appear to me to be done by the same person. The angle of 80° noted on the drawing is wrong. This angle is 90°. Both drawings have this mistake. Also funny how on the more recent drawing they spelled Olson wrong!

    The post 5199 drawing, where did that come from?

    Interesting…both drawings came from Foss…apparently the 5199 was built for an Olson years ago and the new Foss rudder used by Jiri & Jason was originally designed for the Hobie 33. Personally I like the looks of the Larry Tuttle designed rudder but from what I heard…the price point isn’t anywhere near what the Foss Rudders are going for…

    Did the 5199 drawing come from Foss recently, as a result of an inquiry? Just curious more than anything (not trying to give you the 3rd degree!) Yes it’s interesting how they differ slightly.

    Is the image in post 5197 an Olson 30?

    Pic 5197 is the rudder on an Olson 29. Yes.. I am in the market for a replacement offshore rudder for my boat and I inquired with Foss Foam about options…these were the two options they sent…
