Ok,just to muddy the waters a little more: hull
form must be considered when discussing all the above; i.e. finer entry =better speed thru steep chop and less likely chance of getting into irons while tacking in these conditions.
Wide stern =faster down wind
in light boat in significant seaway= more puking
Heavier boat with wine glass section= less puking and more women,less crew.
Lighter boat = less expensive to build( the real reason why today's builders are favoring these craft).
I could go on here ,but if you read all the posts above (most of which are accurate) and then plug
in some of the generalities I have posted you will see why sailing craft design is such an interesting subject and why it provokes so much controversy.
