Hello Frankie, my name is Douglas Suhr, I am Snoopy's current owner. I
would encourage you to ask questions directly on the list so that you
have the benefit of the entire PSUBS community, but if you wish to
email me privately, my email address is spiritofcalypso at gmail.com I
would also recommend reaching out to Alec Smyth at alecsmyth at gmail.com
because not only was he Snoopy's previous owner, but he is responsible
for much of the handiwork that makes Snoopy more than the stock
standard design (live rudder / handheld thruster control box, saddle
tanks, etc.). ~ Doug S.
