Merriman's Submarine Modelling Masterclass

Yes it did. The dorsal 'rudder' on this 1/60th ALBACORE was practical, and as you can see there is very little heeling in tight u/w turns. Also a great 'break' and was part of the 'emergency stern plane jam recovery protocol' on the real boat.

Amazing craftsmanship.

I just saw this on the Web that may be of interest

That Archimedean screw is interesting. I doubt its efficiency though.

I spoke too soon. Now that I've looked at the video, what a magnificent job this guy did for comparing like diameter propellers to a common motor: pump-jet produced the most thrust; the traditional no-rake, no-skew propeller not as good; and the skew-back, moderate rake propeller the worst. The presentation would be complete if this guy indicated motor current draw for each test -- that would give us a Isp for each arrangement. THAT GUY IS GOOD! Not much Craftsmanship on display here (fucking robots!), but damned good engineering came out of his noggin.
 
I am hoping you do one of every kind of submarine, then have each of them scanned.

There are a lot of makers who do quality work--only for their items to fall prey to what I call the Paul Allen Sister Syndrome (PASS).

A guys who carves wooden ducks dies--and two hours after he is put in the ground---the widow bins the whole lot.

Anyone think to put some BB gun CO2 cartridges or air bottles in a larger Seaview replica to give its speed a temporary boost?

These look to reduce cavitation--though with model subs that's part of the attraction.

Explained: The Sharrow Propeller

In this latest article, we thought we would take a closer look at what exactly the Sharrow Propeller is, the technical advancements behind it, and some of the benefits that it can provide.
