Gin Tankage?

[Dockhead]

I was joking with a shipmate about how we'll need gin tankage for next year's Baltic odyssey, and afterwards started to think that maybe it's not such a stupid idea. With up to five or six thirsty sailors on board, the bottles stack up, hard to store when full, hard to dispose of, and expensive to buy. Astronomically expensive in Scandinavia.

You can buy gin in bulk in the UK, from here for example: http://www.alcohols.co.uk/distillery products.php

I wouldn't buy a lot of it before trying it, but I bet it's not bad.

A five liter jug of the concentrate would make 10 liters of gin.

I wonder if anyone has tried storing bulk spirits under a cabinet somewhere, with some kind of dispensing pump at the counter? Any tips? It would save a lot of space, a lot of hassle, and a lot of money.
