General Information
Our objective is to build a vessel that delivers the range, safety, and stable navigation equivalent to the most prestigious full-displacement models. The Alpha 50 LR is engineered to withstand severe storms with winds and waves exceeding 5 meters, surpassing the requirements of the European CE Category A certification, all while offering the added advantage of 15-knot cruise speeds.
This approach stems from a deep analysis of the performance and equipment of pioneering ocean-crossing trawlers (R. Beebe) and modern benchmarks like the Fleming 60 Venture. Furthermore, we have integrated the finest hull characteristics from world-renowned designers such as Ed Monk, P. Bray, T. Fexas, and J. Leishman.
1. Structure and resilience
The hull is engineered for maximum structural strength and safety in open seas.
- Solid fiberglass construction featuring over 18 layers of solid laminate.
- Full-length keel reinforced with over 30 layers.
- Three independent watertight compartments.
- Fuel and water tanks are structurally integrated into the hull, significantly increasing overall rigidity.
2. Functionality and accessibility
The design prioritizes efficient distribution and total access to critical systems:
- Layout designed to allow for seamless inspection and maintenance even while underway.
- Low center of gravity achieved through integrated tankage.
- Center of buoyancy carefully localized resulting in exceptional stability and recovery angles exceeding 50°.
Here is a brief list of Alpha’s innovations:
- Alpha features a double-chine hull design that enhances both stability and fuel efficiency.
- Wide and safe side walks.
- Long keel. Similar to Fleming 55.
- Tender platform ready to be extended.
- For inland cruising, the radar mast on the flybridge can be retracted, reducing air draft to just over 11 feet.
- Three watertight compartments.
- Use of central tanks to keep the right center of buoyancy.
- Alpha is prepared to receive additional equipment (stabilizers, hyd. platform, additional units of air conditioner, oil changer system, etc.).
- Reinforced steering system.
- Optional solar panel system.
The vessel is manufactured and delivered with standard or basic equipment (2 solar panels, electronics, air conditioning, etc.), purposefully omitting complementary equipment that many owners never use. This allows for a price adjustment and offers a direct manufacturer cost. The standard equipment ensures the vessel is ready to begin long-distance voyages with maximum safety and comfort (less equipment means less maintenance).
In the semi-displacement market category, there are no vessels of the same length (50′-52′) that match the spacious access to engines and systems, range, safety, and offshore comfort; with the exception of custom LR (Long Range) vessels built to order, such as the FPB type (S. Dashew) or certain full-displacement models (Nordhavn, Krogen, and Selene).
The vessel also has the advantage of being prepped for the immediate installation of complementary equipment:
-
Stabilizers (gyroscopic or hydraulic)
-
Splendide Washer/Dryer
-
Watermaker
-
Second generator/power plant
-
Lifting system (crane/davit)
-
Climate control systems
With this equipment, the price of the vessel rises to $1’980,000 USD (plus taxes). There is also the option to install twin engines that allow for a 20-knot cruise and a top speed of 26 knots, bringing the price to $2’255,000 USD.
Each model requires approximately eight months for construction. Alpha mandates that all designs maintain completely unobstructed access to electrical installations and plumbing, even when the vessel is ready to sail. The manufacturing of these vessels (custom build) requires additional man-hours. Only two production slots are available per year. Hull number 4 is currently in production.
The builder offers opportunity to acquire a custom design semi-displacement vessel.
List price:
Fully equipped and ready to sail with Cummins QSC 500HP, gen. 14Kw Phasor engines, autopilot, Furuno electronics, etc. (excluding optional features: stabilizer $90k USD, crane $20k USD, watermaker $8k USD, thruster $10k USD).
