I really did not want to seal off the soft tanks completely in my ambient design to keep the "free surfaces" in check. I found the solenoid flood valves unnecessarily complex for my application, plus the issue of access and maintenance.
This is truly bizarre and a testament to the function of this list. Not to encourage off topic discussions but...
The rocket discussion made me think about the pyrotechnics of solid rocket motors, which made me think of flares, which made me think of the time years ago, Freddy got drunk and set his sail cover on fire one July 4th with a hand flare.
That boat had a centerboard trunk!!
Hmmm, centerboard trunk!!....led me to this solution in five minutes!
You guys are just bursting with design ideas!!! :)
Thanks
