About this gift

A birthday for Mum is a calmer gift slot than Christmas — there is room to choose something specific. A chart mug is one piece of the Cornish coast at a time: Mounts Bay, the Helford estuary, the Carrick Roads, the Falmouth approach, the Lands End-to-Scillies stretch. Each design is drawn from a real Admiralty chart, simplified to three colours, fired under-glaze in a small Cornish pottery. £14.99. Made to order, ships in 3 days.

Why a chart for her

Mothers who have a specific Cornish memory tend to remember the place by name and shape rather than by depth and bearing. A chart redraws that shape as a single picture — a bay, an estuary, an approach — small enough to read on a mug. The chart line has been the steadiest birthday-gift category in the brand four years running, partly because the picture is so unambiguous. If she walked the South West Coast Path between Mousehole and Marazion in 1994, the Mounts Bay mug is correct. If she rowed on the Helford with the children, the Helford estuary mug is correct. If she grew up in Falmouth and remembers the harbour with the navy in it, the Falmouth approach mug is correct. The price is the same across the chart line — £14.99 — so the picture is the decision, not the cost. The pair price (£22 for any two) makes the chart a fair gift to give alongside a small printed photograph of the same place; that combination reads as considered rather than performed. We have shipped Helford and Carrick Roads mugs as pairs to seven mothers in 2026 alone.

Why a Cornish illustrated mug

Each chart mug is drawn from a current Admiralty source. The line of the coast is right, the islands are in the right places, the named headlands are in the typeface the Admiralty uses, the rocks marked on the chart are marked on the mug. We do not draw it freehand. The chart itself is then simplified to three colours: a deep ink for the line, a wash for the sea, and an off-white for the land. The print is fired under-glaze, so the picture is part of the ceramic rather than on top of it — meaning a dishwasher does not touch the line over the years. The mug is a standard 11oz white ceramic body with a slightly weighted base. The pottery is in mid-Cornwall, the studio is in West Cornwall, and shipping leaves a post office in Penzance. Mothers we have sent these to often hang one on a kitchen hook so the picture sits at eye level — chart mugs draw well at standing height, which is part of why the line works. The base carries the studio mark, the year, and the chart source.

The charts we draw

Mounts Bay is the most-given chart in the line — the picture runs from Mousehole around to Praa Sands with St Michael's Mount in its tidal causeway. The Helford estuary mug runs the length of the south-coast inlet, with Frenchman's Creek named halfway up and the ferry crossing marked at the mouth. Carrick Roads is the deep channel from Falmouth to Truro, drawn from the Pendennis side. Padstow Bar is the difficult chart on the north coast — the sandbar at the river mouth shifts every winter and the line we drew in 2026 is already out of date for any vessel actually using it. The Lands End to Scillies mug is mostly open sea, which is the point: the Scillies sit small at the western edge and the eye rests on Gugh and Tresco. We are adding St Ives Bay and Fowey Harbour to the line for 2027. None of these are working charts. They are pictures of places, drawn to the same conventions the Admiralty has used since the 19th century.

Buyer notes

Questions buyers ask

How do I pick the right chart?
Pick the chart of the place she actually remembers. Mounts Bay for St Ives / Penzance / Mount's Bay holidays, Helford for the south coast inlets, Carrick Roads for Falmouth, Lands End to Scillies for the far west, Padstow Bar for the north.
Is the chart current?
It is based on a current Admiralty chart, but simplified to read at mug scale. We mark the source year on the base. For navigation use a current chart, not the mug.
Can I add a gift message?
Yes — a single-line message at checkout. We hand-print it on a small card and pack it inside the kraft box. No charge.
