Mounted explosives

[Johnwarosa]

These would be higher-yield version of remote explosives, but would need to be bolted and wired on the ship and detonated using a signal. Usage would include self-destruct sequence to deny loot for pirates or (if wired and placed carefully) blasting part of the ship away to e. g. shield from the fire or just increase speed due to less weight.

I like yor idea. Pirobolt-like beams would be also handy and less harmfil to the ship if you wish to drop something off.
