No experience on that boat, many good reports from her. You have picked just about the best location to do a charter, these days. May is not a bad time to do it either.
Not too sure if that boat does fillets or gut & gill, best to ask, that way you take the right size esky up.
Here's a tip, try to get a hold of a butchers apron or similar. ( Vinnies etc, should have them for a dollar ) Makes wiping your hands easy. You know, all that bait yucky stuff. saves yer clothes as well.
Another tip, always try to get the ' fresh ' bait fillet off the deckie. Also be prepared for the bigger fish around the sunset. Go the big baits. Good luck
