[PSUBS-MAILIST] MBT valve

[Alec Smyth]

Hi John,

Snoopy never stays in the water more than a little while, she's a trailer
toy. Interesting things though the folks with big boats need to think
about! This particular one amazes me, in that while I can understand the
effect in theory... is it really something with a noticeable impact?


Best,

Alec
