Is your chart relying on an 1860 survey?

Footnote to cruising the Scillies: piloting there is a reminder of the importance of proper Admiralty charts, because they show the age of the surveys on which they are based, unlike any of the proprietary ‘vector’ charts available on chartplotters.

The Scillies is a mixed area from this point of view. Some of the surveys of the area were last done in 1860 – 1904 by lead line, probably from boats carried on naval survey ships and rowed up and down in straight lines quite a long way apart, so rocks could easily be missed. Other parts of the islands were surveyed at a range of different dates in the 20th century. Continue reading “Is your chart relying on an 1860 survey?”

Round the islands

Below is the UKHO large scale chart of the Scillies, with green showing where the bottom is exposed at low spring tides. With careful tide calculations it is straightforward moving between the islands, though you have to be mindful of dangerous rocks scattered around the flats.

The old pilot books for the Scillies, one of which we have, give many complicated bearing lines for finding your way around using pairs of landmarks, which are still very useful to know.

Three times lucky

The Scillies are beautiful, but they take much effort to visit, even by public transport, because the air and sea links are from Penzance, right at the far end of Cornwall.

I’ve tried to sail to the Scillies half a dozen times, but only managed to arrive after three of those attempts because of bad weather, which makes the islands a rather precarious place to be: there is no all-weather shelter, and it is an area prone to gales and huge swells. Once, the weather forecast was so bad we gave up trying to go west by the time we got to Dartmouth. (I’ve also passed close by the Scillies quite a few times on races without attempting to go there).

Scillies Vineyard

The island of St Martin’s in the Scillies used to specialise in the growing of spring bulbs and flowers. As the old business has shrunk, a new use has been found for some of the tiny fields with tall hedges that protected the plants from Atlantic storms: England’s remotest vineyard and winery.

Tresco story chiselled in stone

New Grimsby Harbour from Cromwell’s Castle, Tresco to the left, Bryher to the right

On an overgrown, narrow footpath through the bracken near Cromwell’s Castle on Tresco in the Isles of Scilly we came across a modest, well-kept memorial to an extraordinary wartime rescue, invisible through the undergrowth until within a few feet. The inscription tells the story: Continue reading “Tresco story chiselled in stone”
