is a liner a structural member

I have to remove almost the entire port side liner in my T30 to make a repair. Can I just keep it out (it was wasting space anyway) and just build into the hull, or did they provide some sort of structural stiffening?

Liners do provide stiffness. Whether or not yours was factored in is a good question for the builder.

On many modern boats, the liner constitutes an important structural element, and may provide a majority of the rigidity for the hull. The only way you can really find this out is to talk to either the manufacturer (best) or talk to a marine architect (not as good).

On many boats, the use of an interior pan liner has allowed them to not add as much in the way of stringers and other hull reinforcement, yet get effectively the same rigidity for a much lower cost.

Removing the hull liner from just one side may render that side significantly weaker and less rigid than the other side of the boat and allow the boat to torque or twist in ways that it is not designed to.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
