I don't think I saw the disposition of that rudder either!
But it's coming soon.
It's all fine and dandy to experiment. I'm not really 100% behind this clamshell rudder - which won't make any sense, I know, until it's together, so that photos can be taken, and comments made. I did make a full size model in wood but didn't carry it forward into the glassing stage where problems have developed. [and there have been dozens of other projects on the boat to keep the plate-spinner busy]
Did have another idea to spite myself which I now think is more viable. I think it can be engineered much more simply. You have a rudder that is simply cut in half across the blade with one piece socketting into the other. Each piece is made complete and independent of the other. One would slip into the other and simply fastened. I leave the design work to you, professor! Probably not that simple!
If I did not have a full time commitment, I'ld love to do it, really! See if there is any easy way to remove and replace these keel hung rudders without a third party.
Perhaps only a cruiser is interested in a maintainable rudder. Damage to a rudder that can not be removed for repair wherever you are IMCO is dangerous. Not hard to imagine an intense scenario where the hole you have to dig to slip the original rudder out the tube just keeps filling as you dig.
The clamshell rudder (soon to be photoed) uses too many small fastenings (5 bolts) to keep it secure. I'm not happy with small fastenings under water. Glad you're interested!
