Project MegaLine50

Size has the meaning

Motor yachts with a length of 48-50 m, having a registered capacity of more than 500 belong to the class of megayachts. These vessels are subject to the SOLAS Equipment Convention, which has a positive effect on maritime safety.The dimensions of the vessel provide excellent seaworthiness, large areas of the premises, and, as a result, a high level of comfort on board. The fifty-meter mega yacht is capable to solve various problems: as a representative vessel for a corporation, as an owner's vessel, or used in a charter for receiving high-level guests. At the same time, the cost of such a vessel in the construction and operation is not sky-high in comparison with larger yachts.

Unlike the well-known platform "river-sea", on which motor yachts "Severina" & "Baiterek" were implemented having restrictions on overall height and draft, the MegaLine50 is a marine-class representative vessel.

The ideology of the project is based on the latest achievements in marine architecture, research and the experience of the company "ProLine" in the field of creating exclusive motor yachts. The greatest length reaches 50.6 m, which allows for greater comfort, to expand the functional component and, according to the image, to correspond to the concept of "MegaYacht" - a large representative class vessel.

Exterior, driving and seaworthiness

MegaLine50 is a design of a reliable and seaworthy vessel. The visual perception of the exterior is focused primarily on these qualities, namely: a large freeboard height, a developed forecastle (a high side in the bow), general tectonicity and the visual power of the silhouette (like a rock crashing into sea waves fearlessly).

The yacht is structurally made of metal, but conceptually should be closer to plastic vessels, i.e. sharp corners, sharp edges inherent in steel shipbuilding are not allowed. The lines are exceptionally smooth, and the transitions are rounded, but at the same time, it remains possible to make constructions from steel and aluminum. The steel hull has modern contours with a bulbous bow tip, providing exceptionally high driving and seaworthiness. An elegant superstructure, with a developed architecture and wide recreational opportunities, is made of aluminum alloy.

Both active and passive pitching dampers are used for greater comfort on the vessel.

The maximum speed is 15 knots (see specifications), but at the request of the Customer it can be increased up to 16 knots when using a more powerful power plant. The dimensions of the engine room allow to do this.

Design Features

Watercraft - two boats with a rigid bottom and inflatable sides (Rib). Work boat 4.5 m long; Owner's boat 6.2 m. Both boats are equipped with stationary diesel engines running on water jets. This allows to use of the same fuel system for the entire vessel. Watercrafts placed on the tank. This has the following advantages: boats are located outside the recreation area and do not interfere with the rest both guests and passengers (do not take up space); the rise and launch is simplified in bad weather (because during the rise and launch the contact of the boat balloon will occur with a steel hull, and not with balconies, bulwarks, etc.); use of one crane (with a loading capacity of 2 t) for work with both boats; hoisting operations are maximally safe for guests and passengers; boats do not spoil the silhouette, because from many angles they are simply not species; and finally, the captain can control the hoisting process directly from the wheelhouse.

Unified trunk engine room. The exhaust gases of the main engines and diesel generators are vented to the atmosphere through a special design mast in accordance with modern environmental requirements. Gas exhaust systems pass through a single engine room trunk located in the center of the vessel. It also serves to take air into the engine room. This arrangement allows you to optimize the overall location of the vessel.

Galley lift. The organization of space on the yacht allows you to arrange a galley elevator, with which it is possible to supply food and drinks directly from the galley to the upper decks, including the sundeck.


Separation of zones. The internal space on the yacht is organized so that passengers (guests) and the crew do not intersect. Crew members can get access to any point of the yacht (bow - stern at mooring, wheelhouse, galley), bypassing the passenger area. Crew members use their latches, showers, gangways, they have their own salon for eating.

Through internal ladder. A key feature of the shipтАЩs layout is a through internal gangway connecting all decks - from the lower deck to sun deck. It allows, for example, from the main salon to get anywhere in the yacht, both in the inter rooms and on open decks.

Description of the layout of the decks (see drawings of the general arrangement of the vessel)

Deck 0 (from bow to stern). In the bow - forepeak with chain boxes, used as a storeroom for mooring equipment. Onwards to the stern is the crew block, which includes five double cabins with bathrooms and a salon for eating. Further to the stern - four double cabins for guests. Two of them are equipped with separate beds (beds), the rest has double beds. The next compartment is the engine room with the main engines installed in it, diesel generators and other necessary equipment. In the aft - recreation area, including a salon, sauna, massage, bathroom. Through a waterproof door, access to the aft platform is provided.

Deck 1. On the bow there is a double luxury cabin. Further, on the starboard side there is a galley, on the port side there is a cabin for special personnel, then the hall of the central ladder with access to the main deck is located. On the main deck in the area is an electro-hydraulic gangway for going ashore. Next, the main salon, consisting of a dining area and a media zone (watching TV programs, the Internet, tea, coffee), follows the stern. Next, exit to the open deck, where an outdoor salon is arranged, a ladder to the aft platform and a stern electro-hydraulic ladder for going ashore.

Deck 2. In the bow - wheelhouse and captain's cabin. Further on the starboard side are the technical rooms: the emergency diesel generator room and the climate control room. The main part of the deck is occupied by the Owner's block (1st person), which includes: a bedroom, an office, a salon, a bathroom, a room for heating food, as well as a salon on the open deck. Access to the deck is through sliding doors with a large glazing area.

Deck 3 (SanDeck). The inner rooms on the sundeck are as follows:the salon and a lounge with a bar. On the inner ladder you can go down to the lower decks. There are sliding semicircular doors with large glazing for access to the deck. Deck equipment: pool, sofas, tables, chairs and other items for outdoor recreation.

Interior design and layout of rooms can be changed according to the wishes of the Customer.
