Before starting a game players need to fill out a log sheet for their ships. The log sheet has information about the ship's sailing speed for different wind directions, information about the ship (hull points, masts, etc.) guns, and crew. The rules provide this information for a wide variety of ships, from small gunboats all the way up to 1st Rate ships such as HMS Victory and the French Ocean class.
Turn Sequence: Each game turn has four phases: 1) Ship Movement, 2)Combat (ship-to-ship and ship-to shore), 3) Crew Actions, and 4) Record Keeping.
Ship Movement: During this phase the players check for a change in the wind direction, then plot their movement on the log sheets, and finally move their ships.
The distance ships move is determined by their initial relation to the wind at the start of the turn, but can change if the ship changes course during movement. If during movement a ship turns so that the movement rate would be lower than the starting movement rate, some movement is lost and vice-versa if the movement rate increases. The rules have a good example of this, so it shouldn't be too confusing, even for new players. Ships can make a turn (up to 45 degrees) at the start of movement, at the end of movement, and after traveling a certain distance, referred to as the Turn Delay, based on the ship stats. Ship must have a minimum number of crew allocated to sailing the ship (or rowing) and if the crew number falls below this value, the ship simply drifts.
One thing I don't think the rules cover very well is tacking (turning through the wind). The rules basically simplify this task and don't really have rules for getting stuck in irons (heading directly into the wind) other than the ship doesn't move. There also isn't any real difference in crew quality when it comes to sailing.
Combat: After movement, players can fire their guns at other ships and shore targets. First you roll a die for each gun that fires to see if it hits (this value is modified but if you roll a 10 or higher on a D20 you hit). Then, for each gun that hits, you roll for damage and mark that off on the target.
The game has 13 different gun types from rail-mounted swivel guns all the way up to fortress guns. There are also rules for mortars. Each gun type is rated for point blank range, an optimal range, and a drop distance. You get a To Hit bonus if you are within point blank range. If you are over optimal range, you get a negative To Hit modifier for each additional drop distance to the target. The drop modifier is an interesting way of handling maximum ranges, since you can always fire your gun, it just has a lower chance to hit the farther the target. There are some other modifiers too, but they are all fairly common (like ship size).
Each gun type also has a number of crew needed to man it. If the gun has half the needed crew, it can only fire every other turn. If you have less than half crew, you can't fire. Guns can be aimed at the rigging, hull, or deck (where the crew hangs out) and there are different kinds of ammunition, including bar and grapeshot.
Overall, I like the gunnery rules. There are enough different gun types and crew is an important component in firing. The only problem I can see is if you are fighting with larger ships, then you will have to roll a lot of dice.
Crew Actions: After combat, crews can fire small arms, grapple/board enemy ships, and repair their own ship. These are all fairly easy to understand actions, but the players must allocate crew to do them.
One thing I expected to see here was some sort of morale check for a ship, but the rules don't really have rules for checking morale or striking.
Record Keeping: During this phase players check on ship damages (fires, explosions, sinking ships, etc.). Then the turn starts all over again.
That covers the basic rules for the game, but in addition to those rules there are Faction Rules that add special characteristics for ships based on the crew. This is a nice addition, since I like rules that show the difference in naval crews.
There are also optional rules that cover ports (including visiting taverns and recruiting crew), forts, and treasure hunting. All of these are nice add-ons and probably will be a good selling point for gamers that want to play some pirate actions.
Overall it seems like the rules play pretty fast and should work well for a good number of ships and players. It seems like they were created for convention pirate games, so I would expect that to be the case. Although I could see things dragging a bit if there are too many large ships in a game. The sailing rules aren't the strong point for the game, but that isn't too surprising if the main focus was on convention pirate games.
The Sailpower rules are available on Amazon.com or through the Sailpower retail partner, The Soldiery, in Columbus, Ohio. You can also purchase ships and other game accessories through The Soldiery. There is a link to products on the Sailpower blog/website, which has photos of the different ship types available and information for contacting The Soldiery. The blog/website also has optional rules, FAQs, and downloads.
Pros: It should play fast, as long as there aren't too many big ships. I like the different gun types and focus on crew allocation for actions. Should be good for convention games.
Cons: I think the sailing rules could be better (it wouldn't take much to improve them) and there should be a crew morale system.
