I'm sure others will say this too but, the currents are such that a 'yak would have restricted use. Being out in the main Merrimac current would be a no-no, but exploring up inside the Blacks creek (salisbury boat launch) around the top of the tide would be pleasant and productive. Also, I've seen the fish and birds explode at the outlet of the next creek upstream from the boat launch (see aerial) at the start of the outgoing. This would be a short little paddle and you could fish form shore from the bank across from the launch. The basin itself might be fun on a full tide.
