Re: [PSUBS-MAILIST] Community Design Project
Uhhh. We already talked this over about a year ago. We
decided to avoid the K designs altogether, both
because we wanted something completely new, and
because we didn't want to rip off Kittredge (or appear
we were even). In the end, a lot of the project has
been and will continue to be as you describe. No one
really has the time to assume sole responsibility for
any aspect at this point. Hopefully that will change
once construction starts!
I have strongly considered the K250, personally, and
decided against it. I like the simplicity of Thjis'
double-end-cap hull concept and think basically every
other aspect of the K subs can be similarly improved
upon in some way. If the plans were $20 bucks I might
be a bit more tempted...But still not enough.
