George H, you wrote: "And such seat-of-the-pants navigation seems to have applied particularly to American whalers. Although I can't now recall chaper and verse, I've read several accounts of merchant vessels being "spoken" by New England whalers, asking for a position, who hardly knew what ocean they were in." I've read through over thirty logbooks of American whalers specifically, and I don't think that this was true in any general sense. They recorded their position every day, by account if weather did not permit observations, and they sometimes used methods that might have been considered sophisticated, including lunars. But these were practical people, and they used every available method to determine position including "speaking other ships" as often as opportunity allowed. For commercial vessels, this "speaking" is an interesting game. You want as much information as you can get from the other guy without giving up anything too useful yourself. And you added: "Of course, whalers were a rather special case. They would make incredible voyages from New England ports, right through the Pacific and into the Bering Straits, away for four years or so, only sighting land on the passage round the Horn, and sometimes not even then." That's an exaggeration. In fact, they went ashore quite frequently. In the Atlantic, there is a sort of "slalom course" of islands, many large and some very small which will get you down the entire length of the Atlantic with little worry over fresh water and frequent verification of your vessel's position. In the Pacific, it depends a great deal on the decade, but by the 1840s, most of the Pacific was an American lake. There were hundreds of New England whalers at sea in some years. They made frequent port calls in Chile, Peru, the Galapagos, Mexico, California, Japan, a number of small Pacific islands, and Hawaii especially (it's fair to say that Hawaii is a US state today because of the dominance of the American whaling industry in the Pacific in the 19th century). And you concluded: "In mid-ocean, they didn't really care exactly where they were, not making a passage from A to B, but simply wandering in search of "fish". If these were Sperm whales, these could be anywhere on the world's oceans." Whales are found in some areas more than others. These "whaling grounds" were the destinations of whaling voyages. There were many of these, with varying popularity and fishing value. The Pacific just west of the Galapagos was popular. The Gulf of Alaska and in later years, the Sea of Okhotsk were also full of whales. It's true that the vessel's exact position in the whaling ground was unimportant, and I would say that there's good evidence that the position was recorded in the logbook with lower frequency and less accuracy while on the whaling grounds, but they still took every opportunity to determine at least the latitude. For those who haven't been on NavList long, I should mention again that there is a considerable collection of digitized logbooks from 19th century American vessels, including many whaling vessels, available on the web site of Mystic Seaport. For reasons known only to them, they've changed all the URLs for their online collections. The main index of digitized documents is now here: http://library.mysticseaport.org/initiative/MsList.cfm (scroll down to logbooks and journals). It's great stuff, and there are often navigation problems worked in the margins or in back pages. If you want to understand 19th century navigational methods, you have to look at primary sources. -FER --~--~---------~--~----~------------~-------~--~----~ Navigation List archive: www.fer3.com/arc To post, email NavList@fer3.com To , email NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
