<div><font style="background-color: transparent;">The Marin 37 looks about like I remember most of them looking. Perry built a male plug for the prop side and made nice little fiberglass ones off the form. Once the shape was down, they were easy to replicate, rigid in operation, and easy to mount. Just need to find a motor prop combination. Direct drive is simpler and lighter, but gives you less as a result. </font></div>
<div> </div>
<div>The 120 volt motors we used make for a smaller package. About 70# thrust as I recall from a 3/4 hp Perry. It was a good kick-ass motor, but leaked a bit from time to time, and we spent more hours than we wanted to sorting them out. They solved most of the problems with better shaft bearings and a double shaft seal arrangement.</div>
<div> </div>
<div>A decent magnetic coupling would solve most of those problems.</div>

<div><font style="background-color: transparent;">Have a look at the massive changes to The Great White by the Scotts (Cassell and Reed). Big deck, good sized MBTs, etc, and still keeping the weight to about normal (1 1/2 tons according to the web site. Maybe the broad deck lets them scramble in and out--if not with impunity, then perhaps with care. As to canting the dome, I think you could heavy up the mating ring so that it was strong enough to weld elliptically to an angle cut conning tower cylinder and with a good dome, you could push on deeper, certainly to the K-350 and maybe to the K-500 ranges. Still have to fiddle up an internal/external closure for it, though.</font></div>

I remember having researched this issue once upon a time, and I remember it giving me fits finding it. It's the same navy facility in Md mentioned by Alec , "<span class="yiv6360293448mark" id="yiv6360293448misspell-9">Calderock</span>," only he took it a step further having actually called them. It's very hard to find on the website, it's listed under laboratories and facilities as the "deep submergence test facility." <a href="http://www.navsea.navy.mil/nswc/carderock/pub/what/facilities/facilities_list.aspx" target="_blank" rel="nofollow" shape="rect">http://www.navsea.navy.mil/nswc/carderock/pub/what/facilities/facilities_list.aspx</a><br clear="none">

Elsewhere on the site you can find the agreement and cost analysis forms to download. <br clear="none">
So Alec has discovered the prohibitive cost which puts an end to it in my book.<br clear="none">

It turns out that the best case scenario for a test facility for us <span class="yiv6360293448mark" id="yiv6360293448misspell-10">PSubbers</span> is a guy in B.C., with a crane and a
barge, (imagine that!:)!

It occurs to me that if there was a demonstrable benefit to A537, he would have used taken advantage of it. And he didn't, apparently. Interesting. Don't know why, though.

<div class="yiv6360293448MsoNormal"><span style="font-size: 10pt;">A537 plate steel is heat-treated.
