Steering cable tubes on outside of boat

Why has this not been incorporated yet?  I have had 3 skis where plastic tube became dislodged.  Fixing this is nearly impossible without professional help or tearing the boat apart.  As vital as these tubes are, they are barely glued on.  At least flare the ends out so it is impossible to recess back through the opening.  The best solution is to run small recessed exterior channels on top of hull around the seat.  The plastic tube snaps down into the channel.  You would probably never have to replace the tube, but if you did, it is right there to replace in 5 minutes.  If you want steering yolk recessed, just angle the channel and tube down to it from deck.  There is no need for covered, closed rudder compartment.  Cable attachment would be on outside of pedal and fairly high, but that is fine.  Tubes now are not totally straight as they either go under or around seat, so straight line is not a must.  Thoughts?  Any manufacturers reading this?  Thanks.

Vulnerable to damage whilst manhandling or remounting?

The tubes would snap into built-in recessed channels, i.e. the tubes would not sit up on top of deck, which would be vulnerable to damage in remounts, carrying, etc.  The recessed channels keep the tubes out of harms way.

A recessed channel would be great - also very difficult and expensive to mold.

If you knew the history of surf ski design from the very beginning you would see we have progressed from what you suggest to what we have now. Anything external is a potential hazard, hence being internal.

Because of poor construction and manufacturing techniques you want to change the system? How about better quality glues, tubes and skill to stop this from happening. The only way to make the manufacturers do this is to vote with your feet and don't buy that brand. That being said skis are all hand made and people make mistakes, it is then up to the manufacturer to rectify at their expense. Onto another point, if they cannot get the tubes glues in correctly, imagine what your suggestion would look like? To do something like you suggest is MUCH harder to do than you would think.

I replace tubes fairly regularly and no I don't have to cut skis open  to do it but yes you do need a professional to do it. No manufactures is free from this happening, but the percentage is very low in terms of overall numbers, you just hear about the ones that have a problem, not the ones that don't.
