Yes you can fit a battery with a larger capacity (Amp Hours)as long as you have sufficient space and can secure it to satisfy the Boat Safety Inspector. The alternator will charge it, assuming there is nothing wrong with the alternator. However now is a a good time to do a power/energy audit and the charging calculations that you will find in the maintenance notes on tb-training.co.uk. This will help you to ensure you are not going to cause the new battery to wear out before it could by either over discharging or under charging it on a regular basis.

Just to clarify. For any given alternator the time it takes to recharge a battery depends upon how much electricity you have taken out, not the battery or alternator size. If you use the extra capacity to go for longer between charges then it will take longer to recharge.
