Although I have never owned a 542, I have had 3 Campions continuously since 1993. 1993 215 Victoria, 2007 622 Explorer, 2016 682 Explorer.
I put many hours on these boats, almost completely off the west side of the Island and have been satisfied with their performance and capabilities. Although I certainly don't pound out to the banks daily, I do chase the fish through varying sea conditions and don't baby the boat. I have never had any hull problems with these boats.
I'm guessing that you could ask about any brand of boat here and get a variety of opinions and certainly different people have different experiences with their boats. I'm just saying that, in my experience, you shouldn't have to worry about Campion hulls. Now if I was a guide on the west side of the island and was working the offshore waters daily, I probably would choose a different boat but since you are asking about a 542, I'm assuming that you will be careful about the water conditions you run in. The 542 is a small boat for offshore waters and I'm sure you are probably aware that, for open seas, bigger is always better!
Living in Ucluelet, you have access to lots of fishing boats and boaters. Walk the docks and talk to them. You can learn a lot from them but always measure the "opinions" and what they think a boat should be used for. You won't hear an offshore guide recommend a Campion 542 for example. That doesn't mean the 542 is a bad boat, just that it would not be suitable for their use.
By the way, I toured the Campion factory to see my 682 under construction and although I did not witness their glass layup procedures, I was impressed by their facility, their professionalism, and their pride in the boats.
Good luck in your search.
