Lobster Hulls: Unique Design For Special Boats

Lobster boats are the backbone of Maine's lobster fishing industry. These workboats allow the more than 6,000 lobstermen in Maine to haul in their catch. Over the years, lobster boats have changed due to the evolution of marine technology and the increasingly competitive economic battle among those who make their living on the sea.

The classic Maine or Down East-style lobster boat is a semi-displacement vessel notable for a springy sheerline that sweeps aft from a high, flared bow to topsides with low freeboard aft and often considerable tumblehome at the stern. The hull of a lobster boat is typically semi-displacement, or semi-planing. This type of hull is capable of developing a moderate amount of hydrodynamic lift due to its underwater shape, however, most of the boat's weight is still supported through buoyancy with typical power applications.

The Downeast hull type is typically described as being either built-down or skeg-built. The keel being referred to as the skeg. In the built-down type, the shape of the hull forms a graceful reverse curve with considerable dead rise forward and greatly reduced moving aft. With skeg-built boats, the hull is shallower amidships with a flatter bottom and a vertical keel at near right angles to the hull fully aft.

Lobster boats are either 'built-down' or 'skeg-built'

Lobster boats are either built-down or skeg-built, and this refers to how the skeg is attached to the hull. Skeg-built boats have hulls that join the skeg at a perpendicular angle, as though the skeg were an afterthought. Built-down boats, on the other hand, have hulls that curve into the skeg, creating a smooth transition.

Skeg-built boats are generally faster, while built-down boats perform better in heavy weather and can carry a larger load. This difference in performance is due to the shape of the hull, which affects how the boat moves through the water. Built-down boats have more curve to their hulls, which helps them handle rough conditions and carry more weight. Skeg-built boats have a sharper angle where the hull meets the skeg, which reduces drag and allows them to move more quickly through the water.

The choice between a built-down and skeg-built lobster boat often comes down to regional preferences and the specific needs of the lobstermen. Lobster boats with built-down hulls are commonly found in the western regions, while skeg-built hulls are more prevalent in the eastern areas, particularly to the east of Southwest Harbour. Lobstermen in the west may prefer the built-down design as it handles heavier loads and rougher weather, which can be common in that region. In contrast, the faster skeg-built boats in the east may be better suited to the conditions found there.

While the choice of hull design may be influenced by regional preferences, it is important to consider the specific needs of the lobsterman when selecting a boat. Factors such as the typical weather conditions, the amount of cargo that needs to be carried, and the desired speed of the boat should all be taken into account. By carefully considering these factors, lobstermen can choose the boat that best suits their individual needs, ensuring they have a safe and efficient vessel for their work.

Lobster boats have a pronounced keel

Lobster boats, known as the "pickup trucks of the Maine coast," have been refined over the decades to meet the needs of fishermen who tend lobster traps. The pronounced keel of a lobster boat serves to protect the propeller, which is usually set well forward to give a flat shaft angle. This design feature is unique to lobster boats and sets them apart from recreational powerboats that may be labelled as "lobster yachts."

The keel also contributes to the overall stability of the vessel. In general, boats with a keel are less prone to rolling or heeling, which is important for maintaining stability when hoisting heavy lobster traps aboard. The deep forefoot of a lobster boat's keel further enhances its ability to handle head seas and prevents the bow from falling away from the wind during trap retrieval.

In addition to its functional purpose, the keel also plays a role in defining the breed of lobster boat. Lobster boats can be categorised as either "built-down" or "skeg-built," depending on how the skeg is attached to the hull. Built-down lobster boats have hulls that curve into the skeg, resulting in better heavy-weather performance and increased load capacity. On the other hand, skeg-built lobster boats have hulls that join the skeg at a hard angle, making them faster and more prevalent in certain regions.

The pronounced keel of a lobster boat is just one of the many design features that make these vessels uniquely suited to the demands of lobster fishing. It reflects the boat's working nature and distinguishes it from recreational vessels that may borrow aesthetic elements without replicating the true characteristics of a lobster boat.

Lobster boats are round-bottomed

Lobster boats, with their round hulls, tend to roll with the waves and swells when at rest. This is a characteristic shared by other boats with round hulls, such as canoes and kayaks. The rounded hull gives a soft ride, but it rocks back and forth more than a flat-bottomed boat. This instability can be mitigated by the addition of a deep keel or stabilizers.

The classic Maine or Down East-style lobster boat is a semi-displacement vessel with a high, flared bow and low freeboard aft. The high bow is designed to shoulder aside the seas, while the low freeboard makes it easier for the lobsterman to bring their catch aboard. Lobster boats also tend to have a single engine set well forward, giving a flat shaft angle.

The real difference between a real lobster boat and a recreational "lobster yacht" is often found underwater. A true lobster boat has a pronounced keel that protects the propeller, and its hull is round-bottomed without hard chines. Lobster boats are also narrower than recreational powerboats.

There are many "breeds" of lobster boats, including the Jonesport, Beals Island, Hampton, and Cape Islander, and they vary depending on the harbor they hail from. One defining feature of lobster boats is whether they are "built-down" or "skeg-built," which refers to how the skeg is attached. Built-down lobster boats are better heavy-weather boats and can carry larger loads, while skeg-built boats are generally faster.

Lobster boats have a high bow

Lobster boats are a type of vessel used by fishermen to tend to their lobster traps. The classic Maine or Down East-style lobster boat is a semi-displacement vessel with a high, flared bow. The high bow is designed to shoulder aside the seas, while the low freeboard makes it easier for the lobsterman to bring their traps on board.

The bow of a lobster boat is typically high and flared, sweeping aft to topsides with low freeboard. This design allows the boat to cut through the water efficiently, with the high bow providing stability and helping to keep the boat from falling away from the wind when the traps are hoisted. Lobster boats also tend to have a pronounced keel that protects the propeller, and a deep forefoot to handle head seas.

The hull of a lobster boat is typically round-bottomed, without hard chines. This type of hull provides a smooth ride and is well-suited for navigating through waves. Lobster boats are also narrower than recreational powerboats, with a shallow draft, allowing them to manoeuvre easily in small lakes, ponds, and slow-moving rivers.

The high bow of a lobster boat is an essential design feature that contributes to its stability, manoeuvrability, and overall functionality as a working vessel in the Northeast fishing industry.

Lobster boats have a low freeboard

Lobster boats are working vessels used by fishermen to tend to their lobster traps. They are designed with a low freeboard, which makes it easier for the fishermen to hoist their traps aboard. The freeboard of a boat refers to the height of the boat's deck or gunwale from the waterline.

The classic Maine or Down East-style lobster boat is a semi-displacement vessel with a high, flared bow that sweeps aft to topsides with low freeboard. This design allows the boat to shoulder aside the seas while still providing a stable platform for trap fishing.

The low freeboard of lobster boats is a defining characteristic that sets them apart from recreational powerboats, often marketed as "lobster yachts." The practical purpose of the low freeboard is to facilitate the hoisting of lobster traps, making the boat more functional for its intended purpose.

In addition to the low freeboard, lobster boats have other distinctive features. They often have an open pilothouse, allowing a single crew member to work the traps from the helm while still enjoying weather protection. The cockpit typically stretches for more than half the boat's length, and the single engine is positioned forward to create a flat shaft angle.

The underwater design of a lobster boat also differs from recreational vessels. Lobster boats have a pronounced keel that safeguards the propeller, and their hulls are typically round-bottomed without hard chines. The forefoot is usually deep, aiding in handling head seas and keeping the bow steady when hoisting traps.

The traditional lobster boat hull flattens quickly aft, providing both form stability and a good turn of speed when running to and from the traps. These boats are also narrower than recreational powerboats, optimizing their performance for trap fishing in the Northeast coastal waters.
