Hydrophones

[TacCovert4]

From Kirk: I screwed up and hit the wrong button.
One mod-power is editing other folks posts.
In this case I ..um...replaced Tac's argument with my reply.

Sorry.

Tac was observing that 25t was allot for the relatively simple hydrophone array, and 5-10t seems better, any chance of changing that.
...well it was longer, but that's the gist.

My impression is that 10 tons is closer to right. 

However, Hydrophones/ASDIC/SONAR are an area that I just don't know much about.
I've read more books about Subs than about subhunting.

My impression is the 25t is a somewhat arbitrary amount, but it's "enough" .

Some decent digging on why it's too much would seem to be a reasonable basis to change it.

Coincidentally, a book I ordered for myself has an unexpectedly long and detailed section on hydrophones.
Tonnages aren't listed, but there was a variety of ways in which they were mounted.
These ranged from a single microphone, to the more common two
there were towed arrays, there were "towed fish",
there were lines of hydrophones in hull blisters,
etc, etc.

I have not had time to thoroughly read it, but will in a couple weeks.
So with some future work, breaking them into subcategories with differing tonnages seems plausible and defensible.
