Cutter (boat)

A cutter is a name for various types of watercraft. It can apply to the rig (sail plan) of a sailing vessel (but with regional differences in definition), to a governmental enforcement agency vessel (such as a coast guard or border force cutter), to a type of ship's boat which can be used under sail or oars, or, historically, to a type of fast-sailing vessel introduced in the 18th century, some of which were used as small warships.

As a sailing rig, a cutter is a single-masted boat, with two or more headsails.^[a] On the eastern side of the Atlantic, the two headsails on a single mast is the fullest extent of the modern definition. In U.S. waters, a greater level of complexity applies, with the placement of the mast and the rigging details of the bowsprit taken into account – so a boat with two headsails may be classed as a sloop.

Government agencies use the term "cutter" for vessels employed in patrolling their territorial waters and other enforcement activities. This terminology is derived from the sailing cutters which had this sort of role from the 18th century to the end of the 19th century. (See below.) Whilst the details vary from country to country, generally these are small ships that can remain at sea for extended periods and in all usual weather conditions. Many, but not all, are armed. Uses include control of a country's borders and preventing smuggling.

Cutters as ship's boats came into use in the early 18th century (dating which roughly coincides with the decked sailing vessels described below). These were clinker-built open boats which were fitted for propulsion by both oar and sail. They were more optimised for sailing than the barges and pinnaces that were types of ship's boat used in the Royal Navy – one distinctive resulting feature of this was the washstrake added to increase the freeboard. It was pierced with rowlock cut-outs for the oars, so that the thwarts did not need to be set unusually high to achieve the right geometry for efficient use.^[1]: 33

Cutters, as decked sailing vessels designed for speed, came into use in the early part of the 18th century. When first introduced, the term applied largely to the hull form, in the same way that clipper was used almost a hundred years later. Some of these 18th and 19th century examples were rigged as ketches or brigs. However, the typical rig, especially in Naval or revenue protection use, was a single-masted rig setting a huge amount of sail. Square sails were set, as well as a full complement of fore and aft sails. In civilian use, cutters were mostly involved in smuggling. The navy and coastguard therefore also used cutters in an attempt to catch those operating illegally.^{[2]: 119–112}

Decked cutters of 18th and 19th centuries

The term cutter appeared in the early 18th century as a description of a hull type. These vessels were designed for speed and the name was used in a similar way to clipper in the next century. The concept of hull type was perpetuated by the term "cutter brig" which was used over the period circa 1781-1807 for those rigged as brigs. "Cutter built" was a description applied to a hull of this type and designed for speed. More generally, the unmodified word "cutter" soon became associated with a single-masted rig.^{[3]: 26–30}

Fast vessels were often used for illegal purposes, such as smuggling, or by the authorities trying to prevent this illegality. Therefore, cutters were used for both. The Royal Navy bought and had built a large number for use in controlling smuggling, as "advice boats" (carrying dispatches), or against privateers.^[4]: 56

The characteristic cutter hull shape was wide, many had a length to breadth ratio of 3 to 1. It had a lot of deadrise and fine lines. A huge amount of sail could be set on these

The dimensions of an 18th-century cutter purchased by the Royal Navy in 1763, and roughly in the middle of the size range of the batch of 30 bought that year (HMS Fly) are: length on deck 47 feet 6 inches (14.48 m), beam 20 feet 10.25 inches (6.3564 m), measuring just over 78 tons bm. Smuggling cutters ranged from 30 tons (captured in 1747) to 140 tons. The Revenue cutters increased in size to match the vessels they attempted to catch – Repulse, of 210 tons was built in 1778. A determining factor on size was the number of crew needed to handle the large gaff mainsail with its long boom. Larger cutters purchased by the Royal Navy were sometimes converted to brigs to make them easier to handle, but still utilising the fast hull.^{[3]: 26-29 [2]: 120-123 [6]: ch 9}

Ship's boat

thole pins as the pivot point for the oars.^[c] This allowed a higher freeboard, which was helpful if sailing – when the cut-outs were filled with wooden shutters (often mis-called poppets^[d]) to keep the water out. The alternative, if the correct geometry for an efficient rowing position was adopted, was to position the thwarts awkwardly high.^[1]

^{: 32–33, 65}

Like some other types of ship's boats used in the Royal Navy, the cutter appears to have originated in Deal. Some Navy Board correspondence of 1712 concerns disapproval of the captain of HMS Rochester for buying a cutter of about 20 feet (6.1 m) in length as a replacement for her pinnace. In 1722, another ship had a cutter issued for a voyage to India, and by 1740 substantial numbers of cutters were being bought from Deal boatbuilders to equip Navy ships. The size of these boats varied from 15 to 20 feet (4.6 to 6.1 m) in length. ^{[1]: 32–33}

The 1740 purchases coincided with a decision to increase the number of boats carried by warships. During the Seven Years' War cutters were found particularly useful for cruising ships, being seaworthy and useful for boarding. However, they were more susceptible to damage than the heavier boats that they replaced and much less capable of carrying heavy weights, such as anchors and water casks.^{[1]: 32-34, 36-37} The range of sizes available steadily increased. By 1817 the cutters issued came in 17 different lengths, from 12 to 34 feet (3.7 to 10.4 m).^[1]: 63 This big variety was reduced when the Royal Navy's warships moved to steam propulsion. Since drinking water could now be distilled on board, ships no longer needed to have the largest boats that they could carry to maximise the amount of water collected on each trip. The standard-issue cutters from 1877 to 1900 came in 11 different lengths, ranging from 16 to 34 feet (4.9 to 10.4 m). This was cut to 5 sizes from 26 to 34 feet (7.9 to 10.4 m) in 1914.^{[1]: 70–71}

The sailing rig of the cutters used as ship's boats was usually two masted.^[e] In 1761, the larger Deal-built cutters had spritsails set on these masts, soon transitioning to a dipping lug fore-sail and a sprit mizzen. For much of the 19th century, and into the 20th, cutters were rigged with a dipping lug on the foremast and a standing lug on the mizzen. This made them similar to many of the luggers worked from the beaches and harbours of Britain. The sail plan illustration here (1880 Sail Plan) even replicates the civilian lugger terminology of having a fore and mizzen mast, and not using the term "main mast".^[f] A variation on this rig, seen for example in 1887, was to have two dipping lugs.^{[1]: 91–96, 112}

The number of oars pulled varied with the size of the boat. A schedule of ship's boats of 1886 shows 34 to 30 feet (10.4 to 9.1 m) cutters pulling 12 oars, 28 feet (8.5 m), 10 oars, 26 to 20 feet (7.9 to 6.1 m), 8 oars and the two smallest sizes of 18 and 16 feet (5.5 and 4.9 m), 6 oars. The smaller boats could be single banked whilst the larger and later examples were generally

double-banked. For transporting large numbers of men, in moderate weather conditions, a 34 ft cutter could carry a total of 66 men, a 26 ft cutter, 36 men and a 20 ft cutter, 21 men.^[1]

Steam powered ship's boats saw a slow introduction to the Royal Navy from 1864. By 1877, three types were in use: steam launches, picket boats and steam cutters. However, right up to the time of the First World War, the majority of the boats in use continued to be propelled solely by sail and oar.[1]^: 106 The Royal Navy still has some cutters that can be worked under sail or oar.^[4]: 54

Sailing rig

In the simpler definition, the sailing rig called "cutter" has a single mast with

storm jib might be set on a reefed bowsprit, with the bowsprit partially run in from its most fully extended position.^[4]

Cutters have been used for record-breaking attempts and crews have achieved record times for sculling the English Channel (2 h 42 min) in 1996 and for sculling non-stop from London to Paris (4 days 15 min) in 1999.^[11]

Pilot

The pilot cutter developed from the need for a fast boat to take

harbour

to incoming large trading vessels.

As most early pilots were local

fishing boats were heavy working boats, and filled with fishing equipment, they needed a new type of boat; early boats were developed from single masted fishing cutter designs and twin masted yawls

, and latterly into the specialist pilot cutter.

Notes

1. ^ A headsail is a sail set forward (in front) of the mast. It is triangular in shape and the luff (front) may be hanked (fastened) to a stay that supports the mast, or it may be set flying (not attached to any stay). Where two headsails are set, the most forward one is called a jib, and the one nearer the mast is a staysail. A jib topsail may be set as a third sail, positioned above the jib and hoisted to a higher point, such as on a topmast.
2. ^ The roach in a sail is a curve cut into an edge. In this instance, it is a concave curve in the foot, or lower edge, of the square topsail. This allows the sail to set clear of the forestays, yet still have a large vertical extent along the leeches (the vertical edges of a square sail).^[5]: 238
3. ^ The Royal Navy later introduced rowlocks cut into the washstrake in other types of boats, so this is not a reliable method of identifying the type of boat in, say, a photograph
4. ^ A poppet is the vertical piece of timber supporting the washstrake in a boat. The name was commonly mis-used for the neighbouring piece of wood, the shutter that was used to close a rowlock to keep water out.^{[7]: 215–217}
5. ^ The only common example of a Royal Navy ship's boat that had the sailing rig termed "cutter" was the longboat.^{[1]: 92–93}
6. ^ Many British luggers of the 19th century originally had 3 masts: fore, main and mizzen, but during the century, virtually all abandoned the main mast and simply set bigger sails on the foremast and mizzen. It is suggested that this gave more clear space for working fishing nets, handling anchors and cables, etc.^[8]
7. ^ "Running" in this context means it is moveable during the normal operation of the boat – just as a halyard is running rigging and a shroud is standing rigging
8. ^ A sail, especially a jib, is set "flying" when it is not hanked to a stay but instead relies on the tension of the halyard to keep the luff taut^[9]
