 Topic: How eco friendly are dinghys?Posted: 18 Nov 18 at 8:19pm |

Got a friend who has just started sailing and bought a Topaz X thing- he seems to be doing ok in it. But he also keeps sending me adverts for Mirrors and saying, for reasons best know to himself (I would say ignorance) he wants one. With the ones he keeps sending me he may get a nice trailer and some firewood
Which has me thinking Topaz/Mirror more or less same user group. So over the lifetime of any particular one which is the most eco friendly? Topaz - can sit neglected for years in the nettles and shrug it off, but at end of life will be landfill. I'm guessing its not eco friendly to make in first place either. Mirror - (wood) grows on trees. Needs paint stripper, varnish and more paint, epoxy to keep it usable regularly and unlikely to have a long life without it. But at least it can be fed through a woodchipper at end of life. Any thoughts?

Buying a used boat more eco friendly than new (already been manufactured).
Wooden boat more eco friendly than Plywood, GRP, FRP etc etc, minimal chemicals required when using whole wood (planks), all metal bits easilly recycled, regular maintenance of hull and good storage will mean a long life.

Hmm. Hadn't thought about plywood being a manufactured product.
Was thinking of the boats lifetime credentials, rather than owners personal ones by buying new/used. Metal bits apply to all constructions.

Glues used in construction and plywood, epoxy, polyester and vinylester resins in coatings and layup and conventional varnishes are all pretty unfriendly I guess. But a typical boat last 20-40 years + and has a much lower environmental impact than a car (and there are orders of magnitude fewer of them) so I guess we aren't the best sport WRT environmental impact but we're far from the worst too.
Worst case scenario we can shred GRP and use it in construction..... The canoe/kayak industry has gone almost exclusively back to linear polyethylene which is a repairable and recyclable thermoplastic from cross linked PE (which is a thermo-setting plastic and changes it's chemical structure when moulded).

By the time you've allowed for 30 years of annual sanding back (= microplastic) and revarnishing/painting (=solvents) I submit any calc is so vague as to be meaningless...

Sanded my Minisail back yesterday. Only the 5yh time since 1971, as far as I can see, with just one complete strip back. More friendly than my Topper?
Sails should be taken into account, too. If ever all sailors emptied their lofts of old sails, we would have an ecological disaster. |
