Just an FYI I think you got frigates and ships-of-the-line a little blurred. The picture you've got for the frigates is a classic 74, which isn't a frigate. At this time period, frigates only went up to ~28 guns, maybe ~32 at best with light guns (6-pounder to ~12-pounders, I believe.) It wasn't until late 1700s that we got massively armed, 44-gun, 32-pounder heavy frigates that beat speed records, but they were never really regarded as ships-of-the-line, and never really stood in the line of battle. Ships-of-the-line were in their own class and type of ship, and could easily blow your average frigate (with the exception of the latter type that I described which could go toe-to-toe with the smaller fourth-rates) out of the water. Frigates are fairly weatherly, I think you're thinking of the ships-of-the-line, which handle pretty horribly. ;D

I'll have my CS as soon as I can.
