Dodgy build quality???
I cant comment on other manufacturers but the boats we imported from China we had built to our own specification and have had no problems with them whatsoever.
In November last year I also bought an original Thundercat due to an unfortunate soul going through a divorce and it was too cheap to leave alone.
Having both our boats and the Thundercat I can tell you that even though the Thundercat has had no repairs and is in very good condition the tube material is like paper compared with the ones we imported in,also the paint is coming away from the ply floor on the Thundercat and the timber is going to need some cosmetic attention,whereas the marine aluminium in ours is perfect after many outings.
As for using the boats the Thundercat is a bit quicker on take off but thats probably due to it being smaller than the Supacats and the engine is a Yamaha 50 with Boyeson reeds and a stainless prop,whereas the Supacats have got standard Tohatsu 50's on them.
As for the tubes holding air we have no problems with the Supacats apart from the Highjacker tubes on the bottom tend to need topping up every couple of weeks,But,so does the Thundercat.
I AM NOT SLAGGING THE THUNDERCAT,so please dont everyone attack me for this reply,and we are not trying to benefit by importing a container load in,thats not going to happen due to the exchange rate and we couldnt afford to,we have full time jobs anyway.What we did was experiment by sourcing a company (with excellent business feedback) have our boats built to the specification we wanted for durability more than anything else,import the minimum number we could buy and THANK GOD,apart from being ripped off by the BRITISH shipping company who carried out some very underhanded tactics,ended up with boats that we have had and are still having,some excellent fun with that will last some considerable time.
I know that not everyones experience with importing is the same.But maybe more down to luck than judgement we were extremely happy with the outcome and found the company more than willing to assist with our upgrades on their products.
OH GOD i've probably stirred up a hornets nest now and am going to get pulled to shreds,but I can only tell you what happened to us.
