Swimming in Cape Cod Bay Questions

Hi, I was wondering if anybody knew about the waters of Cape Cod Bay. I'd like to do a swim from Plymouth (White Horse Beach looks like a good spot to start) to Provincetown, with a kayak or small boat escort. Does anybody know if this is a relatively safe area? (I am not too familiar with the area) Are there aggressive sharks/poisonous jellyfish/things like that? Also, any currents? If anybody knows the area well, please let me know, thanks!
