Feature request : Add equipment options as a boat characteristics

[nawre]

Would be wonderful if one could add options to a boat. For example :
a contessa could use a

• GPS
• autopilot(GPS based)
• windvane pilot ( https://en.wikipedia.org/wiki/Self-steering_gear#/media/File:Selfsteeringgear.jpg )
• depth sounder
• nav lights
• AIS receiver
• RADAR
• Spinnaker

Each of these options could influence the behavior of the ship and the possibilities.

• 1st example: if I forget to switch on my nav lights and it's dark outside and crossing a traffic separation scheme (TSS) then probability of damage is greater.
• 2nd example : If I only have a windwane pilot, my auto steering is relative to the wind
• 3rd exemple : If I don't have a GPS, the I could only get my position by dead reckoning ( eg astro, daymark, depth sounder .... ) and let the user place his position manually on the map.
