What is Chine?

[jam39vw995]

I've heard this term used to describe a part of a boat.<br />Can someone tell me what this is? Is it the slope or angle and length of the very front of the boat?<br /><br />thanks

jam39vw995.<br /><br />The chine is the hard edge where the side of the boat meets the bottom.

Thanks for the reply, but I still don't understand what you mean.

Looking at the side of your boat, Towards the back,where the side of the boat meets the bottom, That edge is called the chine! Ive always heard it refered to towards the back of the boat, actually, looking at the back of the boat where the transom meets the bottom at the outer corners!<br /><br />Thats a tough one to describe???<br /><br />LubeDude

Re: What is Chine?

ok, thanks. So it's really the edge where the side meets the bottom?<br />How does this affect a boats performance? cornering maybe?<br />sorry for the dumb question.

jam39vw995 <br /><br />Yes, that's it.<br /><br />It will effect a boats handling, especially in turns. A hard chined (ubrupt angle) boat will tend to carve a turn better than a soft chined or rolled chined boat.

also, the hull usually has numerous chines on it's hull. any change in direction on the bottom of the hull is described as a chine. when looking from the side of the boat when it is out of the water, the chines are seen as lines running from the bow to the stern. all boats are different, and how the chines are layed into the hull affects handling, speed, etc.

jam39,<br /><br />Look for a book called Chapmans Piloting. If you need to know it is in there. It has been the bible to many for generations.<br /><br />Doug

I thought the ridges on the hull bottom were lifting strakes, to get more lift on a v-hull with a good amount of deadrise to it, and the outer bottom edges where the sides meet bottom were the chines...

And I believe a reverse chine actually points back in toward the center fo the boat to maintain a biting angle when in a hard corner. This further eliminates chine-walking or side slipping due to centrifigul forces.

Re: What is Chine?

yeah, i was wrong. sorry. i was referring to strakes. chine is the transition from the side and bottom of the hull. and i'm in the navy?

Re: What is Chine?

Chine, chine, chine...chine of fools..oh, wait, that's an anchoring song about chain, isn't it? The chine on a round bottom boat is the same though less easily described than a slab sided boat. A round bottom boat can have a hard chine or a soft chine depending on the angle of the bottom rise to the sides and radius of the "roll" at the chine. Both chine shapes affect the roll motion of a boat as well, either with a 'soft' chine or a 'hard' chine. The lower the angle of deadrise the harder the chine in general terms. A softer chine, a higher angle of deadrise rolls more but is gentler in a seaway and tends to be more directionally stable than a hard chine, i.e., a V bottom vs. a flatbottom boat for example.
