It looks like GL has similar wording, depending upon actual usage
and detailed testing agreed to by GL a service life extension may
be granted. For the person desiring a certified vessel I agree
new windows would probably be a cheaper route unless you were very
sure the existing windows would pass the required testing.
Scratches are a no-no however so you really need to get them
completely buffed out. The heat produced in buffing may justify
annealing however if the windows were manufactured to PVHO
standards there's a lot of safety factor built in.<br clear="none">

<div><span>Yes, that is what I call the bible. I just read on
page 940 that ABS accepts the extrapolation method to
determine remaining service life. The test is very extensive
and for a flat disk window it would probably be cheaper to
buy new windows. I did not see that re- annealing helps.</span></div>
