Baggage limits for the ferry from Shenzhen to HKIA?

Hi there, I will be meeting a friend in SZ(we arrive at different train stations) and need to meet up, and go to the port where we can take the ferry to HKIA. My bags will include two checked items (30kg total) and one cabin size case at 7kg. We will fly with Philippine Airlines to MNL later in the same day. Will it be possible to travel with these on the ferry without incurring extra charges?
