Iron-hulled sailing ships represented the final evolution ofsailing ships at the end of theage of sail. They were built to carry bulk cargo for long distances in the nineteenth and early twentieth centuries. They were the largest of merchant sailing ships, with three to fivemasts andsquare sails, as well as othersail plans. They carriedlumber,guano,grain orore between continents. Later examples had steel hulls. They are sometimes referred to as "windjammers" or "tall ships".[1] Several survive, variously operating asschool ships,museum ships,restaurant ships, andcruise ships.[2]
Iron-hulled sailing ships were mainly built from the 1870s to 1900, whensteamships began to outpace them economically, due to their ability to keep a schedule regardless of the wind. Steel hulls started to become common from 1885, providing an even greater strength to weight ratio.[3]: 89 Even into the twentieth century, sailing ships could hold their own on ultra-long voyages such as Australia to Europe, since they did not require bunkerage for coal nor freshwater for steam, and they were faster than steamers, which usually could barely make 8 knots (15 km/h). Many sailed under the Finnish flag during at least some part of their careers. Ship-ownerGustaf Erikson ofMariehamn,Åland,Finland, was noted for his fleet during theinterwar period. Other sailing ship companies carrying on despite the onset of the machine age wereF. Laeisz ofHamburg and A.D. Bordes ofDunkirk.[4]
The four-masted, iron-hulled ship, introduced in 1875 with the full-riggedCounty of Peebles, represented an especially efficient configuration that prolonged the competitiveness of sail against steam in the later part of the 19th century.[5] The largest example of such ships was the five-mastedfull-rigged shipPreussen, which had a load capacity of 7,800 tons. She was also one of the fastest, regularly logging 16 knots (30 km/h) average speed on transatlantic voyages. Unfortunately speed was her undoing, as she collided with a steamer that underestimated the speed of thePreussen when crossing before her.[6] The second-largest example wasFrance II.[7]
The last large commercial sailing vessels, designed well after theIndustrial Revolution, used engineered iron and steel in their construction. In general, the shipsdisplaced between 2,000 and 5,000 tons[8] and were cheaper than their wooden-hulled counterparts for three main reasons:[9] (1) iron was stronger and enabled larger ship size, capable of delivering considerableeconomies of scale, (2) iron hulls took up less space, allowing more room for cargo in a given hull size, and (3) iron required less maintenance than a wooden hull.
The largesail plans and raked bows of these vessels invite confusion withclippers, but there are significant differences. Clippers were optimized for speed, these vessels were optimized for cargo capacity and ease of handling. Most clippers were of composite construction (iron structure, wooden planking),full rigged and had a cargo capacity of less than 1,000 tonnes; these vessels were iron and steel hulled, usuallybarque rigged, and had far greater cargo capacities. Clippers had already begun to disappear when these vessels emerged.[10]
Typically, such vessels were equipped with steel masts and yards and steel cables, where possible. Often the running rigging was handled by motor-driven winches powered bydonkey engines.[8] The combination of a large, efficient sail plan and hydrodynamic hull allowed these sailing ships to sustain high cruising speeds; most four-masted barques were able to cruise at 15 knots (28 km/h) with favorable winds. Some logged 18 knots (33 km/h) regularly andHerzogin Cecilie is known to have logged 21 knots (39 km/h).[11]
A sailing ship from this era could have a crew of as few as 14, with a typical crew being master, mate,boatswain (bosun), 15 seamen and 5 apprentices.Herzogin Cecilie in 1926 sailed aroundCape Horn with "only 19 men aboard, although not from choice."[12] The crew roster ofPamir on her last commercial voyage around Cape Horn in 1949 under the Finnish flag listed a total complement of 33:[13]
Owners ran their sailing ships with close attention to costs. Officers and essential skilled crew, such as sailmakers, were still paid poorly: the captain ofMoshulu in 1938 received about $100/month and the average sailmaker about $20/month. "The wages of other crew members were minuscule. A skilled able seaman (rated as an A.B.) received not more than, and often much less than, sixteen dollars per month."[14] Crews were readily available in spite of abysmal pay because Germany and Scandinavian countries still required sail experience for mariner's licences.[14]
Discipline, at the end of the 19th century, "especially on American sailing ships, could be brutal, often unnecessarily so."[15] As the end of the sailing ship era drew near by the 1930s, "such tactics had pretty much disappeared in the Finnish ships [and] in the ... German ships." However, even the Finnish mates occasionally enforced discipline with their fists while sailing with minimal crews of largely inexperienced youths when "... instant obedience to orders was essential."[15]
Though a fast-disappearing breed by the 1920s, sailing ships were used commercially until the 1950s. They occupied a niche in the transport of low-value bulk cargoes of little interest to steamship companies, e.g., lumber, coal,guano or grain (60,000 sacks onPamir[16]). Cargoes were carried from remote ports, with fuel and water unavailable, such as Australia (carrying wool or grain), remote Pacific islands (guano) and South America (nitrates). These vessels usually followed theclipper route around the world, ideally carrying different cargoes on each leg of their route, but most frequently sailing in ballast. The last leg from Australia to Europe, where the cargo was wheat or barley, became the source ofThe Great Grain Races as the ships' masters attempted to sail the leg as fast as possible, essentially only for prestige and pride[17] — usually from the grain ports of South Australia'sSpencer Gulf toLizard Point at theCornwall coast and on to the harbour of destination in Britain or continental Europe.
In the 1930s 'good money' could be made in thegrain trade from Australia to Europe, "the carrying rates could vary from perhaps four dollars to eight dollars per ton." The owners of theParma bought their vessel in 1932 for about ten thousand dollars and then loaded over 5,200 tons or 62,650 sacks of grain, for a gross income of $40,000. "The ship paid for herself and all her expenses for the year from the income of that one voyage even though she had sailed in ballast halfway around the world." In most of those years, the ships in the grain trade could clear about $5,000 each.[18]
The Germans in particular maintained profitable commerce through the 1930s to the west coast of South America, shipping general cargo out and nitrates home. They had built powerful vessels, such as thePeking,Padua andPriwall especially for the difficult west-bound voyage around Cape Horn, and their captains were expected to make three round trips around the Horn over a two-year period.[19]
Despite the cost, some of the ships used thePanama Canal, towed by tugs the entire course, avoiding the Horn.[20]
A few suchtall ships can still be seen at international maritime events such asSAIL Amsterdam, theKiel Week andHanse Sail.
The largest remaining original sailing ship is the four-masted barqueMoshulu, today a restaurant ship moored inPhiladelphia, Pennsylvania, United States. The largest sailing ship still in service is a Russianschool ship, the four-masted barqueSTS Sedov. The last metal-hulled sailing ship in original layout is thePommern, today amuseum ship atMariehamn.
