I very much like the idea of using magnets to secure hatches.  I have a few dozen 3/4" diameter, 1/8" thick neodymium disc magnets, in opposing polarity pairs, bought for another project.  These have a 3/16"mm countersunk hole in the centre, so would be easy to fix if used as hatch fasteners.  They are unbelievably powerful - if two opposite polarity magnets are joined together you need to twist a knife blade between them to pull them apart.

I would think that a hatch held down with a few of these around the edge would be every bit as secure as a mechanical fastener, if anything, you might find that it's held down a bit too well, and is difficult to remove.  One advantage (?) is that a magnetic hatch fastener can never become loose; it's either held securely or the hatch is off completely................
