Re: [PSUBS-MAILIST] Diesels
Hi submadmans, just back from an 10 days trip in the north sea on a dive-trawler together with Sgt.Peppers. Boats performce well in both seas- the Baltic and the North Sea. With the new pressure tight Divingcell foam in the sattletanks-endcap and the stern the boat can carry a higher payload and even my 83 Kg / 182 pound heavy friend Stefan can now run the boat. The little new videoskops run fine and gives the boat a much much better performance on the surface with waves - because the hatch can be closed all the time. Boat has now a bilge pump, emergency battery - and a quick battery change switch. All vales and instruments and checklist in the inside now of a permanent type and even a newbie but scuba-diver can dive the boat after a 15 minutes instruction. Boat has a new set of propellers also. Traler was stern-trawler type and we carry the sub on his road trailer to handle it on the deck up to under the A-frame-crane on the stern. No poblems.
Back too the relate item :
I run 40 feet Kraka together with peter two times. First time was in 2005 with the big Diesel behind a sound-bulkhead. But maintance was impossible and after some mechanical trouble because of poor maintance the boat was rebuild. Secoind time I run it Aug.2006 the diesel is now a very compact modern small one and the sound bulkhead is gone - maintance is easy now - and the noise during surfac run is high. We wear ear protection all the time.
But on the othe side - Peter runs the boat to the open sea for more than 24 hours - no pure electric battery boat can do that.

They operated it, but the boys said it was an infernal nuisance, and the thing was moldering in the scrap pile over on 10th Street by the time I saw it. I think the engine ended up in somebody's boat, and the pressure vessel cut up for scrap. I don't think they ever tried it again. Not in my hearing, anyway. Vance

> While visiting George in the winter of 1978-79, I had the opportunity to review this submersible and meet the two gentlemen for whom it was commissioned. The sub was purpose built with a lengthened, flanged hull sealed with a rubber gasket and numerous bolts to aid in maintenance of the diesel. The sub was headed to Alaska for commercial and salvage work. As there was much ice out on the local waterways, the owners were able to practice submersible ops with a K-250 in a large tank next to George’s sub construction barn. I also was able to play in the K-250 towards the end of the day. I received no instruction at all, George figured since I had spent time on subs that I would be safe (almost did not make it up on my last surfacing effort as the scuba tanks were running dry J). Crashed with the owners at a motel in Rocklin where we consumed a fair amount of beer swapping sub stories.

> A few years later, met up with the sub owners once again. While they wouldn’t speak poorly of their expensive investment, there were issues with extreme noise, exhaust fumes, and diesel fumes that made operating the sub to its fullest capabilities impossible. Shortly after the sub was listed for sale and must not have sold readily as the ads were listed for quite some time. Seems to me the asking price was $450K. Believe it was finally sold but don’t know for how much.

Reading operational accounts of some of the early Nordenfeld (SP?), Holland, and others along with the Japanese small submersibles leads me to believe it takes a larger sub to safely mount a diesel. Even the X-craft had many troubles related to diesels in their small confines.
