I am a little biased I like thunder jet personally

saying that a custom weld is better quality is here say

when you take a bottom and side and butt weld them together and throw a lifting strake on it, you get severe chine walk. where the back end of the boat will typically slide from side to side, which on long runs results in arm fatique.
when you build boats like precision weld or HCM or thunderJet you get an actual formed reverse chine hull which will get you on plane quicker and with out the tradional back end slide. not only will it drive straighter but you will be able to turn quicker and with out back end slide.dont forget that a formet side will also make the boat far stronger than a flat side or a lapped or stepped side.
the other thing people dont look at is the components put on each boat such as weld on cleats or dual arm wipers and so on and so on, the list is endless.
when it comes down to buying a new sled test drive every boat possible. if the dealer does not do a test drive then walk!!!
and not comparing boats apples to apples is by far the most common mistake.
