Hi Alan,
Firstly thanks for the kind words, always appreciated.
The rules are home brew and based on a set I wrote for WW2 about 25 years ago, I will probably put them on the blog when they are finished. My dream (?) of publishing a set of Wargaming rules and retirement to a sunny island are long gone so the likelihood is that they will be launched free to air.
I have reservations as they work as a good fun game with a reasonably high degree of accuracy but the rules lawyers will pick holes and disagree with concepts etc and I think can I be bothered, they will be too complicated for some, lacking in detail for others. It's a lot of work to get them out there in an understandable fashion, that and I use ship data cards so there are 150 of them just for Jutland to proof read !
The basics of the ranging is that at the start of the game (or when changing targets) large ships (with directors) throw ranging dice to represent the time spent calculating firing solutions etc.
We use the red dice from the X Wing game but essentially they are d8. A German ships will roll 3 dice a British ship 2 with an extra dice for a ship deemed to have good gunnery skills (eg Queen Mary) or lose a dice for poor gunnery skills. No changes for speed, turns etc just straight dice rolls (a simple way of representing the highly complex calculations involved).
For every 5,6,7 on a d8 (a hit on a X Wing Die) the firing ship records a ranging point on its target, this does no damage but represents the ship getting closer to having a good firing solution. Once a ship has scored three ranging points it is classed as ranged and fires as normal. An 8 on a d8 (crit on XWing) gives a ranging point and a "lucky" actual hit which is resolved as normal causing damage etc. The photo above shows our ranging markers, each clear ring is a ranging point, the red ring is a an actual hit in the previous turn.
You lose one dice for each ship firing at a target, lose one dice moving to the next in line, lose one dice for each turn after the first when a target is masked and on the turn you range in any ranging points over the 3 count as hits.
That's it in a nutshell, hope that makes sense, that's an explanation of one minor part of the rules, you can see how long it would take to explain the whole thing !
All the best Ken
