Unfortunately, folkies are in the minority and predominately elderly. I'm sure councils feel that rate payers money should be spent on catering for the greater majority.

We may also have a different interpretation on what makes a "Maritime " festival.
Both Hull and Scarborough (as seaside towns) have every right to call their events just that.

Perhaps the answer has to be "If you can't beat them - join them". No one can influence events, or bring about change, if they are not involved.
