I have a PVC roundtail (Wetline) dink with an inflatable floor.
I've had it 3 years now and it's very tatty though servicable. I've broken both oars just rowing hard, one I repaired by inserting a tube inside the original and through drilling and bolting where the quick release button was.
I'm very dissapointed with the durability with the PVC. On one occasion I came alongside the dock/steps that were encrusted with small barnicles, despite trying to keep the dink clear she made contact with the dock
and was punctured just below the rubbing strake, This was a problem for patching as it was right where the rubbing strake was stuck, however it was a small leak and I used a sealant
that you pour into the tube turn the tube over and over to get an even coating inside. I could see where the sealant
was coming through so orientated the dink so the leak was at the lowest piont. This worked excellently and I would strongly reccomend the pour in sealant. The inflatable floor is also excellent and if you take a little water
it stays in the bottom so you stay pretty dry.
Although after 3 years my dink is still serviceable I am dissapointed with the durability of the PVC, I have used the dink a lot but only leasure use, I intend to go serious cruising where the 'Dink' becomes like a family
car, ie used every day ferrying back and forth to various docks etc, I honestly believe a Hypalon 'Dink' with a inflatable floor fits the bill.
