How long should a modern GRP hull lasts as compared to one made 10 years
ago?
And how old is considered too old when taking a boat offshore into
potential rough conditions?

There are so many variables, I would think it's virtually impossible to give
a definitive answer.
A well laid up GRP hull should last indefinately, provided it's looked
after. GRP lay-ups vary wildly from make to make and generally speaking,
older offshore boats have thicker hulls utilising low tech materials, many
of which I suspect will outlive more modern lighter build, high tech ones.
In fact, a good
10-20 year old Hallberg Rassey, Contest, Rival, Westerly, Moody etc. may
have a few blisters but will still be stronger than many brand new popular
EU production line boats are today. Having said that, they probably won't
sail as quickly but I know which one I would rather rely on in rough
conditions.
There is no "age" limit for an offshore boat, it depends more on the
build quality, suitability of design and whether the necessary maintenance
and replacement of fittings, rig, etc. has been carried out properly over
the years.
