Hi,
No, I haven't. But I have built model airplanes.
Thoughts concerning RC motorboats...
* I don't see why you can't... I know that there a ton of RC planes out there which are models of real planes. Ditto for boats.
* I would think that full size plans would come in very handy!
* My first concern would be that of scale... I'd try to stick to some easy multiple of the plans scale... Dynamite uses the 1.5":1' example drawn on some plans... That means that the plans are 1/8 the full size boat. Using the plans as a template, that would make for a 2' model. But suppose you want a 22" model... Ouch. Yeah, you can scale it to whatever size you want... (I'd probably go metric and make my own scale ruler... Check out the "Fraction to decimal to mm chart" I put in our Coffee Lounge a while back.) I'd also buy a digital micrometer that can handle both inches and mm.
* As for glues... The general consensus seems to be a urethane glue like Gorilla. (Though I've read that others have used cyanoacrylate, and epoxy. The following is a good thread:

* Here are some great pointers:
http://www.easyrc.com/boats/* As for the motor, I'd go electric inboard, but that's just me. Be sure that the model size will be appropriate for the motor. And I certainly wouldn't use one of those high-speed racing motors. The layout of the interior should be considered too relative to the motor.
* Protecting the wood should be critical. Thin wood warps like crazy when wet.
I don't know much about sailing so I'll leave that alone...
This should make for an interesting thread...
