This programme gives a good flavour of the coble.
Mainly about fishing but Grace gets a brief mention.

The Coble - BBC Radio 3 - 2024
The Essay - A Circumnavigation of the British Isles in Five Traditional Boats   
The coble is the working boat of the northeast of England, with a high stem and knife-like forefoot for facing the breaking waves, but flat-bottomed aft, so it can be launched off the beach and sit upright on the sand at low tide, with not a straight line anywhere.

Katrina Porteous lives on the coast of Northumberland and spent years with coble fishermen, learning their way and languages. Many of the poems in her first collection, The Lost Music focus on the Northumbrian fishing community, about which Katrina has also written in prose in The Bonny Fisher Lad. She weaves verse from her poem The Wund an’ the Wetter, into her unsentimental paean for the coble and the way of life it encapsulated. It's said it takes a village to raise a child; it certainly took a whole community to build a coble, to fish with and maintain one.

With accompanying piping by Chris Orminston.
