Ah, ok now I know where you are.
Someone in the Canadian geological service (forgot
the dept.) has produced some outstanding 3D colour posters of submarine canyons
including, I believe, the type at your link (u/w sand falls). You don
a pair of red/green lenses and WOW!!! Visualising is one thing, seeing is
believing. Sidescanned.
If I find the web site I'll post the
link.
I think transiting is a tough call. Maybe
boredom is the most dangerous issue. At least for me. Falling asleep
and going into a gentle but fatal plunge would no doubt put a crimp in my
day. A dead-man's switch would be a really good idea. Depth alarm,
too.
I don't believe transiting over deep water is
inherently dangerous. Actually, the waves would be gentler, less nasty
currents, too. If something DOES go awry, well, it's hard to argue against
being able to bottom in 60 ft. of water . . . get out, set off your EPIRB, and
listen to the silly SOS's on Ch.16. ;-)
Yeah, vis is to die for. My best vis was not
in tropical water (yet) but up here - 80 - 100 ft. I was ecstatic. I
hear that the Carib has outstanding vis. (Cozumel, Bonaire, Cayman,
etc.)

Rick,
I'm in Ventura, CA . The Channel Islands consist of four
main Islands, Anacapa being the closest to the mainland, just 11 N miles
from the coast. Usually excellent visibility 50' + . The
problem is crossing over from the mainland the depth in the middle area of the
channel goes down to around 600', at the deepest point. If one were to
take their sub across one should have a sub that could handle that depth, to
be on the safe side. If your subs safety factor was deep enough you
could hug the bottom the whole way, assuming of coarse you had enough power to
go 11 miles ! Or you could possibly glide across, glide down half
way and then glide up the rest of the way, then you could conserve your
batteries !
There is a submarine canyon which is also
around 600' deep that comes right into the Oxnard Plain and is most probably
used by the Navy at Point Mugu Navy Base and weapons center. There are
some really cool sand falls that are off the steep canyoun walls.
I stuck a picture at this link:

Brian - you in the Seattle area? MY
concern is being torpedoed by some nuke from Bangor sub base while
transiting from Vancouver to Seattle. Maybe I should play the Doors
rather than cool prerecorded sonar pings over my sound system. The
Juan de Fuca Straight is peppered with sono equipment.

ps: I Googled Annacapa Isl. Says it's in
California - near San Diego?

When I'm crossing the Channel to
Annacapa Island I may have to bank suddenly to avoid a Navy sub
!!

Don't you want to crab into that current while touching
down on the bottom? Naw, maybe you're right. :-)

2 axis
control is good enough. I dont see see a lot of need for cross wind
landing in a submarine.

Hi Peter,
"Repeating others' success is easier than building a better
mousetrap"
An occasional reminder of this and other basics is always
helpful. I have re-thought many details based on this very notion
and every time I am reminded, there is a design improvement.
The Ercoupe reference was simply an example of mechanical
linkage for single yoke / stick, three axis control for
anyone so interested. I wouldn't give up the pedals on an aircraft
but I imagine a sub doesn't have to worry about cross control issues
causing much more trouble than maybe a little drag. My design wont
have roll control at all.

There is a 3-axis joystick that
moves left-right, forward-back, and up-down. Don't remember
where, or who made it, maybe it's on Deep Rover or the Martin
Marietta Manned Maneuvering Unit.
Regarding Ercoupe, many have been
converted to use rudder pedals.
Repeating others' success is
easier than building a better mousetrap.

I'm thinking of a control stick
like aircraft, but to one side (out of the way) and
with a twist. Why not control all three axes from a
single stick? Push/pull for pitch (like an aircraft
elevator), left/right for roll (like aircraft ailerons), and
twist for yaw (like aircraft rudder pedals). This could
eliminate pedals which would enable an exit hatch in the
floor for my ambient dry sub.
Sounds good, but I suspect
somebody here can troubleshoot....
Thanks...
Stan
I've got pics of about half a
meg apiece of my steering wheel/control stick
options.
I don't know what's hapenming
with Moki - jeepers that thing is awkward to
use.
Anyhoo, anyone interested
can let me know and I'll send them
offlist.
These are game control steering
wheels and a joystick. As far as aircraft controls go,
they are extremely light. I'll be adapting them for use
with mechanical linkage, probably drum and cable with eighth
inch S/S marine cable around through
bolted pulleys. There will be NO
computer/motherboard/electronics aboard with the exception of
my depth finder/collision avoidance. The usual
electrics, of course (nav lights, red night lighting,
etc.) I have a knotmeter, depth gauge and
voltmeter. C'est
tout.
