A 38-page collection of fast play rules covering individual ship actions, major battles and featuring an extended campaign system, “Lord of the Sea” is centered set primarily on naval actions in Northern European waters in the 13th to 15th centuries. The rules have been written with 1/1200 scale models in mind, their inspiration being the models designed by Outpost Wargaming Services and others.
The rules mainly use six sided dice (d6), with ten sided dice (d10) used in some circumstances. Unless specifically stated otherwise all die rolls use a d6. Sometimes a d3 roll is called for. In this case roll a d6 and halve the score, rounding up (so a 1 or 2 gives a result of 1, a 3 or 4 gives a result of 2, a 5 or 6 gives a result of 3).
You will need (in addition to models and a playing area) a handful of dice, a ruler measuring in inches, pens and paper. Ship damage states are denoted by markers. Suggestions for more visually attractive markers are given later in the rules. Also included at the end of the rules are sailing templates for caravels and other sailing ships.
