Re attach teak rub rail

[Johnathon123]

So I am on to the next chore/job/thing on the list.

My boat has a rub rail which is about 5 - 7 cm thick with a small chrome strip over it.

The stern corner of the rail has separated from the hull over about 15 cm length from the stern to a maximum of about a cm away from the hull.

Access inside the hull is extremely limited that far back.

So bolting it all back together is not really an option. Can anyone give me a suggestion of how to put this all back together in the best way possible.

As always, thanks in advance.
