Played a few games of it on the weekend - its fast, its furious, and very fun. Plus, you don't need that many boats for a good sized flotilla (1000pts will probably require a 4 x 6 board, and thats either half a dozen boats, or a corvette/minelayer and a few boats). Navigation is a big issue for some - running off the board with the faster boats is a serious concern at times, it can be difficult to get a hit with your guns, and torpedoes require practice. It also needs a few extra washes to get a few more things right, and the book could do with a revision and streamlining - at least the errata helps in that respect.
