The toggle-able compass and an example mof the new telegraph arrow sizes
Edit: Just noticed a major bug where my "steering" rudderangle solution causes rotation to stop happening at 45d to port and 135d to stbd which you may notice is 180d of difference. Going to have to investigate this one, I noticed it when I was checking my longitude addition per cm math precsion.
Subs arnt much use if they can only travel NE through WSW
