Keel strips revisited
« on: September 06, 2011, 01:47:52 PM »

In looking for a way to protect the front of my new SOF (skin-on-frame) kayak, I have looked for something that is not to obvious, but still tough.

On my other kayaks I just use white commerical grade duct tape.  That's the good stuff that has a solid cloth backing.  Ocean State Job Lot has that kind, the last time I looked.  You can see the dense cloth weave compared to the cheap tapes.  I use it a season and then remove it.  Any adhesive that sticks to the keel is easily removed with white gas (Coleman) or Naptha.  Lay it on in as a single piece of tape, while cutting the tape on each side, at the bow curve, and overlapping the excess in shingle fashion to the rear.

For the SOF I found that a clear polyurethane tape works very well.  3M makes 3M 8561 Polyurethane
Adhesive Protective Tape, but pricey at $149 for 36yards, which is the length of a regular roll of duct tape.  Hard to get in less than case quanities.  Less expensive, only because smaller rolls, is ISC Racers tape.  The tape stretches somewhat so less shingling is needed in wrapping around the bow area.  Comes in 9 and 14 mil thickness.  I got 9 mil for $45 for 36 ft.  Seems to be holding up very nicely.  I retaped the Nordkapp which gets a little more abuse than the SOF, so we will see how that holds up.

Here are several references.  You can see many options if you Google using words like "polyurethane guard ics racing helicopter tape".

Mike- Have you tried heating it to wrap the bow bend?

No, the Nordkapp has a gradual curve and the SOF a sharp one.  On both the slit on each side, folded back works nicely.  Heating the tape might thin it on the SOF square keel strip edges.  I will heat it up a little to remove it thought.  Pulled a little of the coating off on the SOF bow removing other thinner poly tape.

At the 3* training last week Greg had a new type of emergency patch. He said it is also available as a Keel strip - it needs to be warmed to bend around the bow and stern.

Keel Eazy

The stuff Greg recommended is Keel Eazy.  It's PVC with a self-adhesive backing and beveled edges.  If you go to their website you can request a free sample.  www.keeleazy.com 

It comes in white, black, red, orange, yellow, blue & green.  You can buy white or black by the foot directly, but they only sell the other colors in 100' lengths.

http://www.kayakacademy.com/Store/RRKEELSTRIP.html sells every color except blue & green by the foot.
