I kayak and fly fish the coast, for the last 3 years I have been using a Wilderness System Tarpon 120. I love the boat because it paddles pretty fast and straight but pretty maneuverable as well. But! I wouldn’t buy it again. For fly fishing there is too much stuff on the deck and you can’t stand up in it. So I have been searching.
The boats I like are the NewCanoe Frontier 12, it is extremely stable but that also makes it a barge to paddle so I will probably only go with it if I add a motor for my long distance excursions (which I do frequently) it is also quite heavy.
The kayak I am currently lusting over is a Crescent CK1 Venture. Completely open deck so great for fly line management, very customizable, about 60lbs and $899. I haven’t paddled one yet but apparently the track well are stand up able and extremely maneuverable for even running rivers and streams. The big problem? Good luck getting one! ACK can’t seem to stock them (even though they have other Crescent models) they are hot and dealers across the nation are selling out quick. It looks like if I am going to get one I will have to go to Dallas , Oklahoma or Arkansas. Check them out! https://www.crescentkayaks.com/product/ck1-venture/
