    I am going to be the new to me owner of a Sirius 21. The boat does not have a trailer but I do have a old tandem wheel boat trailer. Does anyone have the measurements available for the bunk height and width and any other measurements? How should the keel be supported?

    hello Bartman99,
    Here's a link that might help a little.
    http://sailboatdata.com/viewrecord.asp?CLASS_ID=170
    Sailboat data lists the displacement at 2000 lbs. The ballast is listed at around 535 lbs but that would be a very heavy CB, more like 150 to 200 for the CB, just a guess. A 2x board down the center of the trailer should work for support of the CB.
    Can't help with the rest but bunks are the way to go instead of rollers.

    The centerboard of the Sirius 21 is indeed 500 lbs of cast iron swing keel. My trailer has rubber rollers that I lower the keel onto once on the trailer. The bunks are just high enough that the keel clears when fully retracted, but you want to lower it down once on the trailer to reduce strain.
