My 3 year old Honwave has started to degrade to the point where the polymer is leaving marks on the hull when it is alongside.

The irony is that the material that is degrading is the patch on either hull shouting "Honwave" I have tried scraping the surface to remove the sticky stuff but the rot continues and now Honda Marine disown responsibility.

I have assured them that no odd solvents or harsh chemicals have been used , only fresh water and very mild detergent for the scum-line.

I thought that I should share my experience with those who might consider this product and caution that this problem started just over 2 years into the life of the dinghy and despite being cared for, only exposed to the elements for about 3 months per annum and, as it is carried on davits, only actually in the water for about 14 days per year.

I am an organic chemist so I am guessing that this is due to UV degradation and a poor choice of material by the maker. So CAVEAT EMPTOR.
 
Ours did the same.

It is not the material of the dinghy, just the decals.

I used talcum powder to take the stickyness away.

Needed redoing from time to time, but stopped the marking.

UV degradation is the answer. I dont buy those expensive glasses strings but have used 3mm ID sillicone rubber tube-about £1.00 per metre. That goes sticky with UV too. Plastic tube does not, so I am trying that now.

So far, so good!

My old Plastimo is ancient and the blue thin rubbing strips inlayed on the sides started going after we got to Portugal, I used talcum powder to stop it and swmbo made some "chaps" to stop the sun doing more damage.
I would give Honda some serious stick but also fix the issue with talc and a cover

If your useing it in the Med or any ware it's hot , it's going to happen , only one way around it , have chaps made not only will it protect it from tube sun but also save all the rubbing on quay and the boat .
Although I surprise it's happen so soon on a 2 year old dinghy , our old Honda wave was six years old before the problem started. Our new cheap dinghy 500€ touch is now four years old , it looks a right mess but remove the chaps and it new.
 
It seems the problem is very material specific. Our Quicksilver is now 14 years old and not sticky at all. It has been in the Med all its life, no covers and always in the sun. The airdeck went sticky after five years, was replaced under warranty and the new one is still good.
 
Our pvc one is just 6 years old and the chaps have kept the fabric and seams in perfect condition but all the fittings have glue joint failure so I'm part way through a tin of Polymarine 2 part adhesive:ambivalence:
