Hehe!
I've gone for what is the safest, fastest and reversable option, angled side plates. Safest because it keeps the strength in the chine, fastest because it's just a couple of strips of bent metal, and I can always take them off again.
Still don't really know why I'm bothering, but hey, why not? :-)
They may be too short looking at them on the boat now, but we'll see tomorrow. I screwed them to the hull bottom and covered them in sign vinyl to cover the screws and smooth the joins. I'll try and get a video if the weather holds up enough.
