Mostly Build quality..ie..how it was built not with what...is it nice and stiff or all flexion and oil
canny..are their sufficient tabbing on bulkheads or are they glued in..is the hull
joint riveted on or machine screwed and through bolted...on and on..but it can go overboard
like anything else..
bottom line as I see it...
You can go to sea and succeed in anything yourself..but what would you in good conscious recommend to others to do the same in.
I may some day go to Hawaii
in my Irwin
..I would not recommend you buy one to do It in.
I hope that helps..
Comfort is in the mind of the comforted..some like a jerky motion some like sedate that has little to do with capabilities...
