Personally I wouldn't get another cat. Cats are not social creatures, they are on the whole solitary. Whilst they may live happily with family members, usually they only tolerate other cats in their space and both cats are to some extent stressed the whole time by having to watch out for the other cat. The signs are subtle and most humans miss them. Chasing is not necessarily a game - if the same cat always does the chasing then it is likely to be aggressive.
There's no guarantee that Fluff will get on with another cat, it doesn't sound likes she's that impressed with Ash, and given the restricted space they would be living in another cat will have very limited scope for establishing their own territory. Getting a kitten rather than an adult rehome won't solve this. I don't like to think about what would happen if they got into a fight and one or both fell overboard. To be honest I think Fluff is likely to be quite happy by herself once she gets used to the idea.
I've had 15 cats over quite a number of years. I have introduced cats individually and to groups, I ruined the life of my first cat by keeping his little sisters, and I've outright failed with some introductions, despite picking cats very very carefully. Currently I have 4, 2 were bonded when I got them, 1 tolerates them and the 4th has to live in a different house as, despite being perfect on paper to join another group, she wasn't prepared to play ball and get on with the others. At all, ever, and I have the vets bills to prove it.
