Subject: Gavins - just for the fun of it!
Hey all,

I thought it would be fun to take out my gavin (short-body HDPE) for a 
romp in the kelp beds here in monterey to see what it was like in an 
environment a little different than what the gavins are normally used 
in.  I wrote up the report on our local lists and several members 
suggested it would be nice to forward to the larger lists.  So here it is:

---
Executive summary:  Despite the bad weather and wave forecasts, it was 
really good!  Vis 60-70', very little swells, virtually no wind chop at 
all, undetectable surge.

Beto and I were diving Pt Lobos from the shore with our gavin scooters.
   We started at the ramp, pointed the scooters out to bluer waters and
hit the trigger.  The next 40 minutes was pure bliss.  We were zooming
in-and-out of the kelp beds, criss-crossing each other's paths, doing
barrel rolls, zipping in-and-out of pinnacles and other rock formations.
   I couldn't help but laugh most of the time.

We did the "beto dive", which is a dive we've done a number of times in
the past.  This involves heading out at about 330 degrees following the
reefs and pinnacles to about the 130FSW range, turn around and come
back.  Normally we kick on the surface a *long* ways, drop down at
about the 60FSW contour, head out along the reefs, come back, switch to
deco bottle at 70FSW and do our deco as we work our way towards shore.
Normal runtime is about 2 hours.  This time we started right at the
ramp, hit the 60FSW contour in about 6 minutes, hit the 130FSW contour
in an additional 5 minutes, zoomed around the big pinnacle there for a
while, headed back to the kelp and pinnacles around 70FSW and did lots
of circles around the kelp and rocks, zoomed into the cove and zoomed
around with some harbor seals for a while.  Total run-time 40 minutes
and no deco at all!?!  Doing a straight out-and-back we could've done it
in 20 minutes.  This compared to the 2 hours it normally takes (plus the
long surface swim!)  No deco!  And this was with the pitch on the
props only set to 6.

It was such an amazing experience flying along like a seal or fish,
effortlessly flying through the water, weaving through the kelp.  Words
can't describe it.  As Sami says, "Something that fun *must* be illegal!"

And the vis was so good, especially compared to yesterday (5').  It's
astounding what one day will do.

I'm so glad I decided to head down despite the forecasts.  I'm still
glowing (even as I stand here looking at all the gear I have to clean :-) ).

-Dave
