Just a few off the top of my head, I definitely thought there should be more variety, other than all non-pilots using Spyglass, there should just be only 1-2 dedicated spotter i think.
Pilot Equipment
-Mini-Flare gun: Used to signal for help, but can also be used to see into short distance. Same function as beacon flare gun, but difference is reduced to 3/4 distance and limited to only 4 uses per game.
-Sulfur Spray: Similar to Tar Barrel, but sprays flammable material out of both sides of the ship. Coats enemy ship to cause fire damage to be more exaggerated, but can also coat own/allied ships. Should be light yellowish cloud, lasts 20s.
-Anchor: Drops a heavy anchorhead, will stop ship acceleration if it grabs onto objects in world (longer time to stop if higher height from object), allows for on-the-spot turns or stops enemy from pushing you into a rockbed. Can also damage ships below. It only made sense to me that ships would have anchors.
-Trumpet: Sounds off war-like trumpet call, only usable once per 30s, can only be heard on ships in close vicinity. -50 morale on enemy team, +50 morale on same team. I wish there was an actual use to it, would be fun.
Engineer Equipment
-Oiler: Oil can that lubricates gunner rig, increases width of rotation of guns for 30s only. Useful on guns with low width of view, or can help side-guns target same object as front guns easier (balancing of +width needs looking over, ofc)
Gunner Equipment
-Non-tracer rounds: Projectile path is not visible and does not give up location and also dumbs down sound (can still hear if close enough to ship), has effect only on bullet/projectile-like guns (no invisible fire/mines!)
-Sparkler: 1 round only, long loading time. Projectile that latches onto ship and emits blue burst of light every 3 seconds, lasts 15 seconds. Can help track enemy ships trying to escape into fog. Only lights from point of impact, cannot be seen if on opposite side of ship from your point of view.
-Mini-Balloon: Shoots out an inflatable balloon that helps ship rise and only rise, gun is not usable while balloon is out and changing ammo will cut off balloon. Balloon will automatically detach after 10s.
