It's hard to generalize a lot about Taiwan boats other than to say. They had the largest number of facilities for making yachts any place. They made boats for many of the known manufacturers. The only common problem is the consistency with which they were built. Improvised solutions were not uncommon when some trade
, part, or material was in short supply.
Given the age of most of these boats the issue of what country they were made in is less important than the condition they are in right now and the "fixes" various prior owners may have or may have not made. The other issue is many of the boats made were not intended for around the world cruises. Not that they were built poorly but were never sold as such in the first place. They made many many trawlers and almost any type of boat of the period. It was and always has been about the money
. Global economics changes.
It would nice if you could say all Taiwan boats are to be avoided or only buy one of this brand. All (made anywhere) 70's and early 80's boats are to be approached with caution. If they have not been refitted properly recently then it might be a good assumption that they should be considered in need of a total refit
sight unseen. They may have underlying problems or they may not have any. The worst means of examination is reading the brand name.
The only sure fire way to know the state of such a boat is with a marine survey
. Walk away from boats that have major structural problems because they also have the other problems of age on top of the seriously expensive stuff. It could be argued that any boat can be refitted but not always at the best cost with a result that is worth while.
Modern designs are without question better but not always affordable. There are many older boats out there still with abilities suited for many if not most of us. It has and remains all about the money
