Max,
No portlight is inexpensive, of any variety. You must be very careful when you buy these, because you have to plan the
installation and it is not straightforward. All portlight faces are flat, but your hull is not. You will also have an inner hull
liner of some description and depth. So you will have very specific dimensions and you will also need to fabricate a flat mounting
surface to match the portlight design. On top of that, the only safe portlight will also incorporate a compound hinge and
companion deadlight plate. Please remember that in very heavy weather and breaking seas, the portlight can experience several tons
of explosive force. Your life can depend on your choice. Be prepared to spend serious money on these. I have 13, 8 x 16" bronze
portlights that cost me $14,000 without costing the installation.

Hi group,

My Gazelle is lacking portlights. The portholes are 8". I'm looking
for a source for affordable opening portlights of that dimension. Ebay
and google don't yield much. I can't afford bronze, so I'm open to all
materials (including plastic) if they're strong enough for offshore
duty.
