Big windows - dangerous in an ocean-going yacht ?

During the cruising season there would be small cruise ships came into Tahiti for the tourist trade , they had shutters made of alminium that covered the big low down close to the water windows when doing open ocean passages and once in civilization and sheltered water the shutters were removed and put away till the end of the season then replaced for the return ocean voyage back to Canada or where ever they came from . So maybe a shutter for ocean passages could add security .
Remember the window wants to bend and pop inwards so a wide flang and windows fitter into its opening from the outside with a securing ring frame Bolted not just screwed , Also flexable sealers and adhesives to take shock and bending and flex and possabilities of lots of movement .

 

bingo
also consideration must be made for the racking movements
the amount of rack is directly related to the size of the window so a larger window must have an accompanying larger area left open for this movement
IE free of bolts screws or other edge damaging obstructions.

 

yes
I have done this on my last cat and am planning on doing the same on the current build

Hinges and struts are always the issue and how to attach directly to the acrylic/lexan/whatever used.
