Great beginning mate. Really.
I understand you like 50 ft Benes, right?
Otherwise, you just do not, repeat, do not compare apples with oranges. I believe you might have heard this phrase before even if you do not see what it means.
Compare: an IP 31 vs. an IP 40.
Compare: an IP 31 vs. a Bene 31.
Do not compare: an IP 31 vs. a Bene 40.
Getting my drift?
And even then make sure you do not compare a Tartan 37cb vs. Tartan 3700.
YES. Size matters. All other things equal, bigger boats capsize
later. Capsizing is very bad if you want blue water..
YES. Size matter. Bigger boats may/will sail faster. Blue water is vast. Many like to cross it quick.
If you are just looking for people who will agree with you that a bigger bene is better than a smaller swan then why not just get out of the locker allright and tell us you want to buy a bene 50 and sail it blue water?
It is just my view. One data point. Draw your own regression line.
