Thanks for that Cliff,
I am intending to have my flood valve high &
use it as a pressure relief valve.
The thought just came to mind that if you had your
hatch locked down on a hot day
& put the boat in the water, the cooling of air
inside might make the hatch very
difficult to open. I think I'll keep the pressure
relief valve open in such a case
until I'm inside.
Regards Alan

These adjustable draw latches have worked fine on the R300. They
develop enough force to compress the hatch O-ring. The hatch seal
works fine. The seal does not leak. They do not have an
outside release mechanism other than removing the viewport retaining
ring that is held by a series of allen head bolts.
On my next boat, I will go with the hatch mechanism similiar to that used
on Deepworker 2000.

Cliff's Hatch Closure Mechanism.
Cliff, if you're about.
I noticed your hatch closure mechanism seems to
be a simple adjustable toggle latch.
I bought a few of these a while back thinking I
may use them.
How have they turned out? Do they exert enough
force? Are you getting any water in?
Also do you have any way of opening these from
the outside in an emergency,
or is the
"Big Hammer" the emergency opening device?
