Such as on the Northumberland Straight, bands of flat water occur parallel to the coastline.

There are a number of possible reasons. There can be calm areas in shallow water, as answer 1 says, because longer waves are not sustained in shallow water due to energy dissipation caused by water friction on the bottom, and also due to plant growth which absorbs wave energy. Sand bars can create bands of shallow water. Also, wind itself can be streaky due to obstructions on land, gusts and turbulence.

This could be related to shallow/deep water. Usually when there's a transition like that, you know that there's a difference in the depth of the water. Also, it could be becuase there's a strong undercurrent, and the surface is not affected.
No guarantee on my answer.
