Trying to get better about following up on threads I start.
I did end up using West
epoxy, as I had it on hand and it seemed a plenty viable glue to use. Worked well (did wet it out unthinned first then used some thickened), after clean up of the still uncured epoxy I can only see a very tiny line where the break used to be (i.e. it's not invisible, but close to it). We shall see how it fairs with UV (although when the
boat is not out cruising the
dinghy lives on top of this
hatch so no UV exposure except when we're actively using the boat).
Unsure if it is as strong as the original unbroken piece on the other side, but anyone I catch stepping on it is in big trouble anyway!
Thanks for everyone's input.
