We are currently cruising in Australia, three months ago we left New
Zealand.

We have noted in both countries that companion way hatches are commonly
frameless polycarbon (lexan) or perspex. The lexan ones look about 5/16
inches thick and the perspex ones abouit 1/2 inch. Scratching does not
seem to be a problem.

The frameless construction seems much lighter and simpler that the
laminated wood on Leonidas, and both materials are strong and stiff enough
not to need a frame.
