[PSUBS-MAILIST] SUBSAFE

["Cliff Redus" <dr_redus@devtex.net>]

Ray, why reinvent the wheel in developing a PSUB specification book.?  ABS
and Lloyds are recognized standards to design and build to.  If you can't
afford the price for full certification, which is probably the case for most
of us, then you can at least adhere to the design guidelines.

A more useful approach to newbies would be to develop a defacto standard by
posting at PSUBS detailed engineering plans, that include calculations,
drawings and documentation of a rock-solid simple design similar to say the
K-350.  The level of documentation I am referring to would be equivalent to
that which would be required by ABS certification.  For those only interest
in building, they could go right to fabrication from these plans.  For those
interested in designing their own, they would at least have a solid starting
point and would see the level of analysis necessary to design a safe boat.
The problem newbies have is they are starting from a black piece of paper!
The problem as always is, where do you get the PSUBS plans.

Cliff
