Leisure batteries are good.
If in doubt use something like an "068" car battery. Go for as big Ah rating as you can in terms of space available, weight etc.

Car battery is ok to get you out of a hole id an 065 in mine for few weeks but would recommend it as they run down fairly quick as nothings keeping them charged

Id recommend a leisure battery as the slow cycle in them are more reliable an will last alot longer, no harm to have a cheap multimeter aswell as you can keep a check on it

Nothing's keeping them charged? Surely the engine is keeping them charged. There is nothing draining them when not in use and fitted with an isolator.
I've used car/jeep batteries in my boats for years without issue. Users make their choices!!

lead acid batteries do discharge internally even if not connected, ive have heard an approximation
of 1% per day, if you look around any marina most of the boats will have
some kind of solar panel or wind generator to counteract this and thats using proper
deep cycle batteries
