You can go online and find data on which boat brands stopped using wood in structural applications and what year they stopped. That is the best indicator of how to eliminate future problems.
Fished yesterday afternoon/eve from 2pm to 7pm. Motored out of Sandy Pond and headed to 140 ft in front of the Salmon river. Rough ride to get there but tolerable when trolling. Good temp down in the 120 ft range. Only one 12 lb Coho on a Warrior Salmon Candy for nearly 4 1/2 hrs of trolling. Had a few boats nearby and never saw any activity on any of them.
