Ok, here goes.
Has anybody got a big D off cut about 18” long that they wish to sell?
Poly marine’s D section is £13.50 + Vat p/meter, not too expensive I know but somebody must have an off cut to get rid of.
Also I need to know what is the definitive method of preparation and sticking rubber D strake to a PVC rib.

Thanks in advance and over to all you sticky Ribneter’s

i sent for a slightly different approach
Or you can have one of these - cant remember what it cost now though - as I made a last minute change to the spec to have it added.

I don't see how that stops the rope rubbing on the tube under load.

I always leave the rope loose over the bow - I only tie off to the cleat to stop the rope from flying around. When mooring or anchoring, I always put the load on the D-Ring, never over the tube to the cleat. I then run 'safety' or 'backup' lines over the tubes to the cleat - so should anything give way (D-Ring or more likely the clip) it will hold as a last resort. Generally any ropes over the tubes aren't under any load whatsoever.

Im confused - I never said it did - its an alternative to the bit of cut down D strake being discussed here.

Best way to stop rope damaging your tube when under load is thread it through a standard bit of hose pipe - rope can slide up and down inside the hose pipe and your tubes don't get damaged - I use this method for a rope boarding ladder - works a treat.

If however we are just talking about guiding a rope - then these cleat style fairleads will work just as well as cut down strake and look much better.

Sorry - I thought the idea was to stop tube wear as well as to guide the rope.

As a rope guide, then yes, I agree, yours looks the biz!!

If this thread is about tube protection from an anchor rope over a bow then surely the d-strake option is not going to work - as the boat bobs up and down and swings from side to side the rope is going to come out of the strake anyway and end up directly on the tube.

Yes - I agree with you!!

The only time I would (perhaps) find it useful is if I was actually working on the boat (mooring/anchoring etc) so rope was going over the tube under load. As I said, I never leave the boat with loaded lines over the tubes.

That's the main reson for not putting anything on mine, either a cleat or a D section bit of tube.

Mark - that does look impresive protection - but im still not convinced that in some chop that the rope is not going to dislodge from between that strake

i had one of these fitted as i wanted something to tie to the wall or side with that would lift the rope away from the toobs but would use the lower d link on front of keel for anchoring etc
