So, I want a 18 ft bowrider. Deadrise 17 or 21 degrees; will I feel the difference???

[Moulin6801]

Hey guys, thanks to previous posts, now I know what deadrise is. Now, lets say a 18ft bowrider using it on a choppy lake/river, can I feel the difference while I am anchored fishing or just hanging out on how the boat sways and rocks, or this talk about the angle is overrated???
Thanks
David

While riding down the lake, the 21 in theory should cut through the waves better. At anchor in rough water, it may be better, but probably not noticeable as it is 4 degrees. In smooth water, in theory it should be worse, but again, it is 4 degrees. There could be other aspecks that influence it more than 4 degrees of deadrise.

I don't think that the original issues concerning the construction of a boat with more or less deadrise was on anyone's mind when it was concieved as to what it's effects were standing still. The steeper the deadrise at the transom - the better the boat will ride in heavier sea's. If you had a smaller boat with too much deadrise you would have a pretty weird stability issue when stopped - I would think. I suppose I'll just leave all of that up to the designer's and engineer's.

It will ride better through rough water. At rest, a vee-hull will have more side-to-side movement than a flat bottom.​

Boy that's a loaded question, the resolution i found was a 19' 20 degree with a 8' beam, that is a sharp v for a good ride and wide width for stablitly when stationay........there's a old saying.........there is no substitue for wheel base......

Some mfg's will compromise with lenght but cut the width down and put in large chine's......anytime ive ridden in a boat with large chine's fast that is and rough water my old kidney's get woke up badly. Makes for a dam stable boat though when at anchor. I have a 17 foot Starcraft that could handle 2 people hanging over the edge and not even dip, but in a 1 foot chop it will kill ya......

Where are you boating? Old Hickory and Percy Priest?

I doubt you'll encounter much there that you will notice that difference in deadrise. Get her out in some 4'ers though and you'll wish you had more regardless!!!​

As stated, it depends on your intended usage. Anything under 20 degrees will beat the fillings out of your teeth if running in rough stuff. The more deadrise you have the better the ride. The down side is that the more deadrise you have the more HP you require and you'll loose a bit of speed.

On the other hand a higher deadrise hull will rock a bit more at drift, assuming you have enough wave action to move it in the first place. Maybe a concern in areas with a lot of wave action and on boats with even higher deadrises but shouldn't be a concern in a 20 degree hull.

I personally would opt for the higher deadrise.

Deadrise is not the only factor in determing how a boat will ride. It sounds good on paper, but doesn't work out so simply in the real world. I doubt you will be able to feel the difference.
