It depends somewhat on what you mean by "better". Some people like Greenland style boats which tend to be hard chined and they can be easiliy implemented in stitch and glue. But I think that with careful design either method can produce equally good boats. I like strip-built because it gives a little more design freedom. For example you can make a hard-chined stripper if you want.

A rounded hull will generally have a little less wetted surface which is potentially more efficient, but there are other considerations for a "good" design.

Choose the design you like the best, it will probably be the best design for you.

: does anybody know something about the performance of a stitch and glue kayak
: in comparision to a strip build one ?
: I believe, that a strip build performs better, but how much ? I have the

: glue". What are you thinking about ?
