I use: seafaring hull, combat ram, jod, 3 oxhead, merchant, seafaring & morale deck upgrades, combat captain (with 4x +100 combat traits). That's 8452/8240/8394 m/c/s base stats (morale shipwright), with personal boosts it works out to 8463/8343/8456 for me. If my captain had slayer instead of 1x plucky it'd be better :(. How did your captain get that good? Did you just keep trying and trying until you got the right one or did you use the captain trait missions?
