[PSUBS-MAILIST] sub launch

[Alan via Personal_Submersibles]

Yes, you don't want it coming off the trailer & sitting in the mud.
What happened to your floating trailer idea? Or can you fit air bags low down
on the sub, just to aid buoyancy for tricky launching.
   Ok here's another idea that you are well capable of implementing..... you
have a floating trailer with pontoons down either side & twin outboards on the
end of the pontoons. You drive your trailer in far enough to get the props under,
then use outboard power to pull the trailer out till it's floating then use it as a tender 
to get to your dive spot.!

Gamma has a raked guard now, hmmmm you got me thinking, might be less work.  I am not in love with the sub sitting on rollers though.

>> Hi all,
>> I have been pondering the age old problem of launching in shallow water.  I am making new fibreglass MBT's for Gamma in a few weeks or so, I will increase the diameter to give me more free board.  The steel tanks are a bit to heavy and could use more volume.  Also the thruster tubes will be vectored in the new tanks.
>> But that will only help with launching in shallow water a bit.  I am thinking that typically the water is deep enough for the sub alone without the trailer.  So my plan is to install an A frame on the trailer that can lift the sub when it is backed into the water.  The sub is light at this point, so lifting it off the trailer is easy and then the A frame tilts back dragging the sub off the trailer.  To load the sub, just drive it up to the back of the trailer and hook the cable to the lifting eye, then tilt the A frame forward, it lifts the sub and drags it onto the trailer.  I figure I will need a roller on the end of the trailer to help the sub slide ahead.
