Waited until you were level forty? :-) Well, congratulations to you too, anyway!
Here are my screen shots from July 5th. I finally defeated bridges 8 & 9 - as long as I made it past Goliath at the very start, it would just be a normal long-range sailing battle (actually turned out to be easier than a Juggernaut.) This time, I did make it away from Goliath without getting hit...so I ran until it was off compass, turned, used my remaining lightning shots on the masts, then had to get back on the wheel...eight broadside hits later...victory.
