Skipjack 1/72

[He Who Shall Not Be Named]

So what did you think of the Bedford Incident? Was it worthwhile from a Submarine modelers perspective. I just read a review of it.

I love that movie. Richard Widmark at his best. Also find and watch Hell and High Water -- in that one Widmark plays a sub skipper. I wish we had a President today who had the balls and follow-through depicted by the typical character Richard Widmark would play. These are not times for a Community Organizing College Professor!

Here he is pushing an old lady down the stairs. My kind of guy!

I dont think so Redboat, it gets to be too big to be a bubble of air.

I don't remember seeing the sub other then 1 second of the sail and then the rest of the movie the scope and snorkel. Looked like a Type XXI scope and snorkel.
Very good movie with lots of Cold War tension. The end was great, but only if you remembered the one line stated in the beginning about the Russian subs nuclear torpedo payload.

Back to Clearwater today. The new snorkle valve worked great. I love running a sub in the water with a periscope sticking up to ply the water. A very interesting phenomenon appeared. As she was running along submerged at various speeds, I saw behind the masts ,what I thought was some weeds or something. Upon closer examination, its a(what Ill call)a vacuum air bubble. Ive seen this many times before on a boat, at the rear of the hull or sponson. As the object moves thru the water, there is a momentary void where the water has been pushed out of the way for just a second. The water of course quickly fills in the void, but not before you have seen it. When the scope is just below the surface of the water, this void forms behind it and gets bigger and bigger the faster you go. Ive seen it up to about 1&1/2" long. However, as you go deeper it shrinks then disappears. I theorize that the increase in the weight of the water above it will prevent it from forming with an increase in depth. Im sorry! Im so easily entertained. Im sure I will lie awake tonight just thinking about it.[ATTACH=CONFIG]26316[/ATTACH][ATTACH=CONFIG]26317[/ATTACH]In these two poor photographs you can see it forming right behind the masts at the top.

FYI it's not Cavitation. It's called Interfacial Aeration or Air Entrainment. A bubble of air becomes entrapped within the turbulent flow between the air-water boundary parallel to the flow.

Now, thats an idea. I have red ,green and white marker lights on the Seaview, but then again , its light grey in color and is easily seen. Also, I think that the deck details, like the ballast vents get a ring of white around them, thatll help too.

And Another Thing! I cant find any use for these Sail planes. It operates, I can see that underwater, but it doesnt do what I would think that it would do. Ill keep playing with them but...............As far as the stern planes, if its going slow, it takes almost full application of them to get it under, and as soon as it gets under, youd better haul back on the stick or itll be in the mud. However, if you put more speed on the boat it doesnt take much at all to get her under.
As you increase speed, for every notch that you increase speed you need to hit up on the stern planes a corresponding notch or it will just go deeper and deeper. If your just put-sing around with her, you wont have to worry about it at all.
And by the way, those two scopes that I just put on her, they cause a tremendous amount of drag. If you are trying to win any speed contests, leave the scopes off, she was a lot faster before. But the scopes stay! Its JUST WRONG, to have a sub without at least something sticking up(LOL)

Beautiful pictures of the scopes going through the water. Reminds me of the old movie I just watched "The Bedford Incident". You are right about Sub colors, they are probably hard to see for the average RCer. Can you use Nav lights to see the sub? I've even been thinking about a strobe for emergencies.

Thanks Tom. Good work on the Neptune by the way. I was taking some hard turns today, laying the sail right over and coming out of the corner at speed. Visibility is everything, If I push it too far and it does head for the bottom, I can stop it. But not If I cant see it. Once I paint it black and red, visibility will plummet. Thats where things like bright sun and polarized glasses come into play. Also color contrasts also help, like the silver shaft and the light colored upper surface of the scopes. Perhaps also the International orange hatches will help as well.

Mark, that looks great! Love the periscope breaking the surface.
Great photos too!

Thanks for Humoring me. Now, taking pictures and driving at the same time,is a challenge. Also, this boat, out in the bright sun with its natural whitish appearance is almost blinding. I think that the camera has trouble focusing on it. Now that Im pretty much finished testing and adjusting, the next step will be prepping it for a paint job. There are some areas to be "Evercoated" and blended. Also the prop needs to be bronze plated.
