One of my two remaining, can't part with them boats, is a North Shore Ocean 17. I bought this boat about 10 years ago, as my primary skill development and play boat. It has become much more than that, and in fact, I frequently use it for week long paddling trips and longer. It is perhaps the most versatile, and one of the best all around kayaks that I have ever paddled. My Lootas is the other kayak I won't part with. The North Shore is a skeg boat and It is very different from the North American designs that I have long used and loved for expedition travel.

But, it is a fairly tight fit for me, even though I have lost 5 kilos or so since buying it. The seat is the standard Valley/North Shore unit.

A good seat, comfortable and goes well with the fit and style of the boat. Once inside, I am part of the boat for all intents and purposes. "Fits like a glove" is the perfect description. But, I have to sit on the rear of the deck behind the combing to get my legs inside the boat. I am now quite accomplished at this and in fact need to do the same thing to get into my Nimbus Lootas. I guess you could say I like to wear my kayaks.

Now about the back band: The problem with this seat back is the flimsy nature of the ABS plastic that is supposed to support the back rest. Early on, not being used to getting into a tight fitting cockpit, I managed to "crush" the ABS backing that supports the foam back portion of the backrest. I have pondered, played with, and even changed the backrest on many occasions over the years. With not much success. I had begun to consider a Nimbus "Creature Comfort Seat" as a replacement this spring. I have even looked at them at Western Canoeing twice when I was in the Fraser Valley in the past few months. Totally doable, the North Shore seat is affixed with four screws and can be easily removed. But I kept thinking that the Valley Seat was more appropriate, if I could fix the flimsy ABS support problem. If I could just figure out how to reinforce the back rest and band with a stiffer suport strip?

I have finally managed to figure it out. My solution was to cut a piece of thick ABS plastic, much like that used in Seaward Kayak seat backs to a 10 cm width with a rounded tab that slips into the base of the North Shore backrest. I took a heat gun to the crushed and bent ABS support and then clamped it between two pieces of wood to staighten it out and cool it flat in place. Once cooled, I glued the stiff ABS plastic support in place and secured it with four rivets to hold it permanently and securely.

I adjusted the reinforced seat back this morning to fit, and took the boat out for a two hour trial paddle. It works perfectly as intended. It was back band bliss: stiff, secure, comfortable and supportive. In my 72nd year, I need good back support to continue to paddle, and this has been a thorn in my quiver for several years. So, finally success and comfort in paddling my Ocean 17.

Happiness is a comfortable kayak that fits you well.

Cheers, Rick
 
Nice boat, so many times when you see a great looking boat, the seat is the worst part of its design. It’s interesting how us kayakers can make them better, stronger and more bombproof than factory issue, quite often with just a simple fix.

I have an old ski injury which destroyed a disk in my lower back. So backrests are problematic for me and I typically must reconfigure them. I did a clumsy modification to my Valley 17.3 Etain with the same backrest as Rick's. So, like John, I'll be interested in some photos. As a counter example, the backrest in my composite CD Squamish is perfect.

Not certain how useful these images will be: the top one is the back of the seat showing the rivets, second one is the the seat back from the front, last one is the abs plastic insert glued and riveted inside the seat between the outer support plastic and the padded seat back.

Cheers, Rick
