Tips from me include after you have applied the strake run a bead of sikaflex under the bottom edge of the strake particulary the last 1/3 of the strake on either side toward the back end.

Then Dip your finger in some fairy liquid and water (50/50) then smooth over the sikaflex for glass perfect finish. This will prevent water spraying up and lifting that bottom edge off the tube.


I would wait for summer to do this or find some space indoors that can be heated.

Prime the strake with a coat of glue and leave to dry for 24 hours then apply another priming coat when you do the first priming coat Hypalon then one final coat So 3 coats on the strake and 2 on the Hypalon (you could do 3 on the Hypalon if you wanted.)

Otherwise its not as scary as it sounds just be methodical and prep the areas well.
Best photo to hand sorry

Was there a D fender all the way around before, or has just one of the 5 flat strip fenders come away on each side?

I'm not sure mate. All I know is the very bottom is missing as it's covered in old glue. The centre doesn't look like it's had anything on.

True enough, if it failed, you'd be back where you started (aside from a little CA on the surfaces) but I think the OP was doing a fresh install, not a repair. In his case, if it failed, you'd have two long pieces of strake at the bottom of the sea.

Wish I was closer to you Paul, I'd pay you to do it.

Unusually for me I agree with Codders. Cyanoacrylate adhesive is a superb rubber glue. Whilst totally unsuitable for applying a whole rubbing strake, it is a very good adhesive to carry aboard your rib. Unlike hypalon adhesive which hates water, cyano will work fine in damp conditions. Because it is hard in texture, one might consider it to be incompatible with a material such as rubber but it is not inflexible and it can deal fairly well with flexing.

Here's a wee test I did a few of minutes ago. It's hypalon fabric, the glue area is about 8x6 and it's been stuck together for less than 2 minutes so not even fully cured. The spring balance is pulled to about 20lbs. Apologies for the poor quality - it's tricky taking a photo with one hand while pulling a balance with the other!

That pic is the neoprene side and it actually took the full load on the balance without failing. Another test was with the hypalon sides together and it failed at about 22lbs. Still pretty good for a quick joint. The material has been kicking about my garage for years and it had no cleaning prior to gluing so kinda representative of an emergency boat repair.

Also is a pic of my thumbnail which split at the cuticle last October. Cyano superglue has held it together since and prevented infection, and all sorts of other stuff, getting in. It's good for first aid on skin too.

Don't knock it until you've tried it.

I think you'll find that water cures CA adhesives. As I recall, the emergency procedure for a large spill is to water it down (cures the adhesive, allows scraping it up without bonding clean-up tools to floor and such.)

Given that, damp may be OK, but wet may set off a prematurely cured bond.

There are many, many different CA formulations. Some are very brittle. Others have some plasticizers or something that make it flexible. I have no idea what the relative bond strengths are, though.

Pic quality was fine. Though a real mariner would have tied a line to the scale, pulled it taut, and hitched it off to something.

The test comes as the material flexes and stretches, as boats do as the tubes expand, contract, and bounce over waves. Not sure you could simulate that while taking pictures, though.

It's a great emergency wound closure. Stings like hell, though, if you need to close a slit.

I have tried it. I've seen others try it. As you said, it's a good (perhaps great) emergency bonding agent. In an emergency, use whatever you have at hand. That said, I still would not recommend it as a primary installation adhesive, which is where this started.
