[PSUBS-MAILIST] Trustworthy launch

[James Frankland]

Hi Scott,
Congratulations on your launch!  Sounds like it went well, even if the boat
was a bit light.  Gives me an idea of how much weight i need for mine now.

Can you tell me how thick your endcaps are?  Mine are spun and so are 13mm
thick at the flange.  This makes them pretty heavy.

I lifted the sub onto the trailer yesterday but the driver couldnt tell me
the weight as his gauge only kicked in at 5 tonns.  He described lifting
the boat as "like lifting a matchbox".  Not sure if thats good or not..!

Anyway, great to hear your in the water.
Kind Regards
James
