We've been boating at Winni for only few years now and truly love it, trying to go as often as possible. We enjoy all of the lake, the Broads included, although I don't consider it a destination, "lets go to the Broads today". Depending on where you are on the lake it's really a cross over to get from A to B wherever those points happen to be. I'm sure I haven't seen or experienced by far the worst it has to offer but I've been out when it's really "honkin". I'm one of those nuts that likes it when it gets hairy I suppose because I grew up on the ocean. My wife (and dog, Sadie) not so much. We have a 21 foot BR which is much better in the rough than our 1st 17 footer. I have a Stingray Hydrofoil mounted on the outdrive which really helps me trim the bow up at low speeds when it gets real sloppy. We just take it slow so we don't pound and really the most fun is "running" back home, riding and surfing the waves. Makes my day, anyway. But it's always good to check conditions before crossing; you can always stay closer to home or stick closer to shore for the day.
Be safe and enjoy, enjoy, enjoy!!!
