Yes. So my understanding of how one would do that (in CAD) is to create cylinders of the R0.X radii, and then pitch the sections by θ and wrap...
Ah HA!!!!! I believe I've got it. In a somewhat unexpected development (and unlike what I believe I understood from the videos of other prop...
I tried doing the 0.3R profile as well, and while it's better the leading edge is still clearly not right. I'm completely confused. I've watched...
Well, I think I'm making some progress. The video was extremely helpful, and I got a couple of photos of the relevant pages from PNA. Working...
Thanks! Unfortunately that's a rather expensive volume and the San Francisco public library doesn't have a copy. I'll ask around and see if I...
Hi, folks. I posted this - I think appropriately - in the props forum, but that forum appears to be pretty infrequently read relative to this...
Howdy, folks. I'm working on a low-budget (ie: don't send me to PropCAD) project that requires me to model a KA propeller (or similar). The...
Clearly an I/O would be great for layout, but I'm not a fan. Not only does it have "boat sinking" implications in that you're relying on an...
Thanks for the reply, Barry. First off, I'm 100% clear that the hull shape alone is not a boat design. I've got the experience with boat...
So here's a somewhat revised version of the lines. Less deadrise aft transitioning to a sharper entry. Doesn't show a skeg, but I'd plan to...
Pretty sure I understand the "high initial stability" concept. The chine flats were intended to create a degree of that. I guess what I'm...
I've thought about that. Would that add considerably to the drag (ie: make the whole thing less efficient)? I was kind of thinking that with the...
Folks, I built a boat a while back, and am contemplating building another. Having been unable to find a set of plans that meets my "needs" I'm...
Howdy. I'm in the process of redoing the teak sole in my cockpit (a prior owner belt sanded it to about 1/16" thick and it was beyond repair)....
