Re: [PSUBS-MAILIST] radar

["Sean T. Stevenson" <cast55@telus.net>]

Well Dan, I think it is necessary to point out that, while the vast majority of
us can not afford to undertake large scale projects like the Euronaut, the
defining factor that makes a sub a Psub is not its size, but rather the fact
that it is a non-commercial venture undertaken by a hobbyist.  That said, there
certainly are boats out there which are designed to operate untended, by virtue
of having the capabilities normally relegated to surface support - sufficient
power, range, endurance, weather handling ability, communications, crew comfort,
collision regs compliance, etc.  Unless I am mistaken, the Euronaut falls into
this category.  (I'll leave it to Carsten to comment further).  Such a sub would
likely be of sufficient size to accomodate outfitting it in accordance with the
equipment normally carried on surface vessels - and be capable of supporting a
superstructure that can get a radar scanner high enough to be useful.  My design
is a design exercise only, but it is of a larger vessel with design criteria
including sufficient freeboard to maintain a weather deck large enough to
accomodate an evacuation via stretcher lift (one person lying down, tended by
one or two more), and a weight buoyancy statement which will, with all tanks
empty, maintain stability with the entire ship's complement (6) on the weather
deck in a reasonable sea state - this is in case of fire or other event which
necessitates evacuating to the deck, in the surfaced condition.  The point being
that for most smaller psubs, you're probably right, but there is a place in the
psub universe for vessels designed to cruise on the surface, and in this
context, radar is not a bad idea.
