How to use the duck floatie?

[Twice Twice]

I paid 2000 for this thing - how do I actually use it? It says it'll rescue a sailor from a destroyed enemy ship, but I see no place to use items during battle. Been wondering what the bombs are for, too.

Its used automatically if you have a prison cell onboard you ship.

... pretty sure the duckies are used to save your own crew should they board an enemy ship and it happens to sink. There's a screen at the end of the battle to use the floaties then.
Prisoners are imprisoned as long as you have enough cells, no need for the duck floatie.

Bombs can be thrown by your sailors at icebergs during battle, I think.

i know this is old but the bombs are also used to . . . help you . . . access . . . something :)

When I first started, I had crew members blasted overboard and lost. After I bought the duckie float, I noticed that I never have any members overboard anymore.
I hope Jardar can address how does this duckie float work.
