We have attached the panel to the charge controller and are attaching the fused tails to the leisure batteries. Do we need to disconnect from the battery when we run the boat engine

Simple answer is no. Complicated answer is that on a cool bright day with very fully charged batteries the alternator may not charge but as soon as you discharge the batteries a bit it will start again so its nothing to worry about. You might also find the warning lamp glows and the buzzer "chirps" to you under such conditions, Again it will stop when the batteries are discharged a little.

Always remember the golden rule unless your controller instructions say different. Connect the batteries to the controller first and the panel to the controller last. This stops the controller seeing the potential 21V plus of an open circuited panel and setting itself for a 24 volt bank. Also keep the fuse in the controller to battery lead as close to the battery end as is practical. Its job is to protect the cable from burning if it shorted to metal because of battery current. The controller end does not need protecting because the panels can only produce a limited amount of current. From your initial question I get the impression that you know all this but better safe than sorry.
