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, 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?
