Okay, this is kind of a gameplay thing, but it's mostly because I'm a history weenie:
There's no indication really that the French and Spanish were on the same side, not in the legend, certainly not in the fact that there's 3 pairs of french and spanish ships locked together without an additional locked-in british ship to at least make it look good. Plus there's the whole "opposing nations" part of the locked-ship instructions, and the history weenie in me wants to remind teenagers playing on this map that will certainly be their first detailed exposure to the Battle (high school history class doesn't leave a lot of room in the broader context of the age of napoleon to dedicate to a ship-by-ship analysis of trafalgar) that the french and spanish are technically not opposing sides.
It's really those 3 pairs (Intrepid-Rayo, Indomptable-San Leonardo, and Berwick-Argonauta) that present the problem, since you do need at least some level of connectivity between the fleets. I don't want to get rid of the connections, but I'm wondering if there's a better,more historically accurate way to depict them (though I'm buggered if I know off the top of my head what that might be, but I suspect it would just be a rewording of the instructions). If there isn't, then so be it, and I'll tell the history weenie to stfu.
EDIT: oh, and Bellerplion should be Bellerophon
