What's a reverse hard chine?

I’m looking at a local CL ad for a Kevlar Boreal Design Ellesmere 17’. http://nmi.craigslist.org/boa/5467185099.html

Reading the boat’s specs at the Boreal site, it states it has a reverse hard chine.

I know what a hard chine is but have never heard of a reverse hard chine.


The hull indents a bit at the chine
rather than staying flat. I would say convex or concave but I am not sure which it would be, since it’d depend on whether you were describing the hull from inside the cockpit or from looking at the hull outside.

The Ellesmere has rocking what is usually called secondary stability, and I found it to have a pretty comfortable cockpit fit. It will move sideways when you stop to look at the view in a beam wind, but all boats get kicked around somehow.

take a look at this link on a boating
discussion board. Scroll down a bit to the second post by GoFirstClass, see hull E.

I used to deal with Boreal about 15 years ago. The Elsemere and Pakeseo (sp?) have a hard chine but instead of it following the upward sweep of the deck towards the bow the chine edges dive to meet the keel at the base of bows rake. When heeled over on edge it behaves as a keel lined in the direction of your turn (skidding not carving). It makes for a nimble kayak with a cool looking shape to the hull.

Thank you for the education.

That diagram was excellent.

A picture is worth a thousand words?


You can directly compare it to a couple other hard chined kayaks. I might describe it as multi-chined. The “reversed curve” is referring to the section created between the two chines.

It’s always hard to know exactly how much that modifies the behavior of the kayak. But in paddling it, I’d be hard-pressed to suggest it wasn’t a good idea. I’m a fan of the rounded arch for the bottom of the hull for enhancing the efficiency/maneuverability spectrum. All put together, it makes for a fun, playful hull that still maintains good efficiency.

You have all of those compromises in kayak design, and this is one of those blends where I think they did a great job of improving aspects without overly compromising another. A good amount of overall rocker, and volume in the ends for riding waves, without making it sluggish. A rounded bottom to improve efficiency and maneuverability, while maintaining a comfortable, performance-oriented stability profile. She maneuvers like she was built for it, and then she responds to your forward stroke like she wasn’t just built for maneuverability.

The Ellesmere is a fun, well-mannered performance kayak.

note to OP
The Ellesmere in the referenced CL ad has the smaller cockpit opening. The Ellesmere was also available with a full sized keyhole, easier to get into and out of for those of us with compromised flexibility.

Although hard to see, it also looks like this Ellesmere has the dial style skeg - which I rather like.

I’ve had various kayaks over the years and the Ellesmere is my favorite for the sort of kayaking I do. Right now it is garaged for the winter, whimpering for attention.

Big yes for pictures

Enjoyed both videos. Thanks. Pretty boat, looks like fun to paddle, but I'm hesitant about a 17-foot boat.

My preference is a 15' LV, 16' tops.

I would love to try the Ellesmere, though. If it's still listed through April, maybe I'll give the guy a call.

rsevenic, what's the standard cockpit outfitting like? Did you have to customize yours?

I wonder whose GP he’s selling
he has a score of paddles for sale also.

The phone is listed to

Rendezvous Outfitters.


Last update on its website was 2005 so I'm unsure if the ice breaker sale is still on.

I just learned something new

either oc or keyhole
Either provided by vendor.
