The writer had frequent communications with the late Captain Huddart, of the Trinity-House of London, and other nautical men, both as to the form of a vessel, and the moorings proper for a situation like the Bell Rock: here the depth of water could not be less than from seventeen to nineteen fathoms at the lowest tide, whereas, on the English coast, the depth where floating lights are, in general, moored, does not exceed seven or eight fathoms, and their moorings, consequently, much more easily managed. The writer had also visited the floating light of the Nore, at the entrance of the river Thames; and he was induced, upon the whole, to conclude, that a vessel built after the manner and construction of the Dutch fishing-doggers, would be the most suitable for riding at anchor in the open sea, and that her moorings should consist partly of an iron chain, and partly of a hempen cable. _Pharos Floating Light-ship._ [Sidenote: Fishing Dogger purchased, and named The Pharos.] In the year 1806, a great number of vessels were taken by our cruizers, upon the coasts of Holland, Denmark, and Norway, many of which were carried into Leith to be sold. One of these, a Prussian, which happened to be captured while fishing on the Dogger Bank, was purchased for the Bell Rock service. This vessel was of a flat construction, rounded off both at the stem and stern, agreeably to the ordinary make of these doggers. She was called the Tonge Gerrit, but was afterwards named the Pharos, in allusion to the celebrated Pharos of Alexandria. She measured 67 feet in length, and 16 feet in breadth, upon deck, 8 feet depth of hold, and was 82 tons register. It was, however, only the form of her hull that fitted her for our purpose; her rigging and whole equipment having to undergo a complete alteration, for the light-house service. [Sidenote: Fitted out under the direction of the Trinity-House, Leith.] The establishing of a floating-light being quite new upon the coast of Scotland, and that every thing connected with this vessel might be done upon the best principles, the writer procured the assistance of Mr Joseph Webb, an experienced pilot of Yarmouth, who had attended the fitting up of one of the floating lights stationed off that coast, and who had been recommended by the Trinity Board of London as a person of skill, for instructing the master of the vessel in all the details of the service. Several of the Captains of the Trinity-House of Leith also obligingly formed themselves into a committee, and from time to time assisted in giving directions as to the necessary repairs and outfit of the vessel.
