I'm angling for more risk management in my games of Uncharted Seas, so I'm trying some tweaks to the basic system.
First, in addition to making small ships more difficult for capital class ships to hit, any pair of 3 results on any attack dice roll will score an additional hit against a large class ship.
Second, replace the effect of a stern rake position. Rather than adding a +1 DRM for a stern rake, consider any Damage Rating to score a Critical Hit instead, and enough hits to score a Critical Rating will roll twice for Critical Hits.
Finally, when a friendly ship partially blocks the LOS from a firing ship to an enemy target, then the full complement of attack dice are rolled. All misses, however, will be rolled against the friendly ship, possibly scoring damage as friendly fire.
