I troll with my boat quite a bit and it does just fine. The only downside to trolling is that if you are slow trolling directly into 3-4' steep seas, you will slam a little, and can take some green water over the bow. Of course, this is when you are trolling very slow, if you move the speed up to around 10 knots, then problem is lessened greatly. There is a guy who has a Glacier Bay a few spaces down from me (his name is Skin on this board) and he trolled up wahoo, dolphin and a sailfish a couple of sundays ago so he seems to have no problems trolling either.
I really think that the reason that there are not more cats out there is pretty simple. There are not nearly as many made. If you want a new catamaran, you have basically 7 manufacturers (GB,World Cat,Twin Vee, Pro-kat,Renaissance Prowler, Kevlacat, Sea Cat) to choose from verses hundreds of mono hull manufacturers. Also, monohulls have been the traditional design of choice in America for years, and it is hard to change that trend. Basically, the American boat consumer is conditioned to buy mono hulls, which are faster and much better looking in my opinion.
There is no perfect boat. You pretty much have to make up your mind as to what boat works best for you, especially since you are the one making the payments.
Just to make sure that I was understood. I am not necessarily of the opinion that Cats $uck as trolling machines. I do have too much anxiety about my observation as to the seeming trend of snapper guys with cats and tuna/billfish guys with monohulls to actually plunk down the large dollars for a boat I plan to have for a while. After all, since the ride is inarguably superior in a cat, why isn't everybody running them? Since I spend about 3/4 of the time chasing pelagics I want to make sure that the hull I choose is best suited for that activity. As for the boat not making the fisherman, absolutely. But in an all other things being equal game, which this is, it's a good idea to pay attention to what you really want. You don't have to read this board long to see plenty of sad stories about the boat/fisherman marriage not working out. Hopefully that will smooth any feathers that I inadvertantly ruffled and maybe someone will post up whether they have made the same observation in boat owner trend and the guys that drag baits behind cats will discuss the wake issue.
