I use Alvey reels for surfcasting, haven’t tried their boat reels although I’m using an Alvey 550C sidecaster in the kayak for now because my spinning reels have issues. Alveys have their pros and cons, the reason I use them is that they don’t crap out easily like a lot of other reels do – I got sick of spinning reels only lasting a trip or two before the drag stops working, then another 3 or 4 trips before more serious problems set in. I guess you get what you pay for, and it pays to always rinse saltwater out if any gets in your reel.
