Re: [PSUBS-MAILIST] OSS
Hey all,
Well, for my part, I'm a listener and a sideliner. Part of those of the group who may be several years and several thousand dollars out from actually starting to build their own Psub, due to financial or other concerns. I don't add much to discussion here but I sure do learn a lot.
My two cents is that I believe the OSS should remain on the current mail list we have now. That way those people like myself here can add something if they see a topic that piques their interest, and they can also easily keep track of where the project is headed. I think it allows for a more fluid creative environment, more flexible design process.
As for the new sub? Three or four hundred feet max depth, 6-8 knots max speed, two hours endurance, good window visibility, and good looks. That's all I'm looking for.
Thanks for listening.
