Hello Clive, Well it looks like we have another live aboard sub guy. Kraka is for sale and a pretty boat at that, but there's nothing like building your own to keep you busy. It also sounds like you will need a larger sub then Kraka. That will be a project that will keep you busy for a day or two. I'm working on a trimaran live aboard design for better surface stability as well as work/recreation space. The mermaids need a place to sub bathe ya know. ;)' I expect to spend a lot of time on the surface more like a yacht, so I'm not going for a military shaped sub. I think that a wave piercing design will work well for me. I have been thinking about different options for enclosing a manipulator arm in a hydrodynamic enclosure while underway. I've also been thinking about modifying or making a Lenco type linier electric actuator for external use on a sub. http://www.lencomarine.com/actuator.html http://www.lencomarine.com/trimtabs.html Regards, Brent Hartwig > From: pirate@arach.net.au > To: personal_submersibles@psubs.org > Subject: Re: [PSUBS-MAILIST] sub plans > Date: Mon, 25 Feb 2008 12:30:15 +0900 > > Gday again Ian. > At the moment I am just in the thinking phase prior to design phase, these > are my thoughts to date. > Built as a yacht that can be lived on for periods up to about one month with > 6 persons on the surface. > An endurance of 24 hours underwater for 6 persons with emergency air and > power for 5 days. > Air cooled diesel (surface) and 4 x 72 volt electric motors (submerged). > 40 inch acrylic hemispherical viewport in the bow for pilot and 4 x 10 inch > viewports for observers and C S television astern and above. > A manipulator arm at the lower bow operated electrically rather than > hydraulically. > I have no ideas as yet as to the type of batteries that would be most > suitable, external saltwater batteries would be interesting but would not > deliver anything like the power needed for the main drive etc but may be > useful for emergencies and lights etc ( very low power but long life ). > Able to fill air tanks while travelling on the surface and with a depth > capability of 600 feet. > These are just basic ideas at this stage and the reality may be quiet > different subject to cost etc but it would cut out the cost of a support > ship. > A friend of mine who builds ROV's as a hobby and myself have an interest in > marine salvage and this is the purpose the sub will be used for. > Well I will leave it at that for now and see what ideas I get back. > Cheers Clive. > > > > ----- Original Message ----- > From: "irox" <irox@ix.netcom.com> > To: <personal_submersibles@psubs.org> > Sent: Saturday, February 23, 2008 2:32 PM > Subject: Re: [PSUBS-MAILIST] sub plans > > > > > > Hi Clive, > > > > welcome to the list! > > > > I don't know of any available plans for a 4 to 6 person submarine.
