This theme could be endless posting, to make it short :
What is your inflatable boating experience in years, how many brands have you had/have, how many were hand glued, how many were welded, how do you know Korean fabrics are not so good ? Accoring to your small number of post on this forum, you have started from 0 as everybody does, so maybe giving plain theory read from other forums instead of 100% personal experience. Experience & practice, not theory, is needed to state if a product is good or bad.
Have had many brand inflatables pvc, hyaplon, akron fabrics and found no welded one is better than hand glued ones, welded seams will need to be hand glued when spliting with time, welded boats have also hand glued parts, Welding is faster, needs less factory work, reduces costs & saves space.
Reputed brands as Achilles, ABS, Gommonautica, Caribe, just to mention some, are making their boats hand glued, so if any other brand manufacturer is using quality fabrics, proper 2 parts glue and assemble facilities with controlled temperature environments, will have a perfect quality finished product. Anyway you cannot compare the welding that Zodiac makes on their boats, has light years of experience and top quality welding agents to any Asian manufacturer welding. As all in life, will have welded & hand glued tube lovers and detractors.
All is reduced to treat, cared for, correct air pressure inflation and where is kept & stored. I believe in first purchase, If you want to take the nail out for yourself, go to the dealer store, see a live boat, check warranty issues.
Mooseknuckles, If the boat will be used just for recreational purposes as mentioned, go for it.
Happy Boating
