2009 Lagoon 420 Owners Version

Listed

Seller's Description

Dear fellow cruisers,

With a bittersweet note, we announce that our beloved Seabear is seeking new horizons. Having been our floating home and guardian through captivating Bahamian waters and along the vibrant US East Coast, she has provided us with comfort and safety in every tide while cruising full-time. As an Owner’s Version, she is roomy, cozy, and perfect for extended stays on board.

Now moored in the historic sailing town of Annapolis, Maryland, Seabear is ready for her next chapter.

In true German fashion, we’ve meticulously maintained and upgraded her, ensuring she’s in top condition for her next adventure. The 2023 enhancements alone speak volumes: new bottom paint, a complete sail drive overhaul by certified Yanmar technicians, all-new standing rigging, a fresh Quantum mainsail, and a state-of-the-art life raft.

But perhaps Seabear’s most distinctive feature is its formidable solar power setup, ensuring that you’re powered for continuous adventure. The top-notch Victron hardware keeps you in charge no matter where you find yourself. In combination with the Catalina Watermaker and Starlink Internet, it promises off-grid, sustainable voyages.

We’re inviting offers at $399,000 for Seabear, a testament to her value and the promise of adventures to come. For those interested or with queries, feel free to reach out via email.

We will be able to provide an extensive Google photo album featuring around 80 interior and exterior shots, offering a closer look at what makes her special.

Moreover, we’ve documented part of our journey with Seabear on Instagram and YouTube, providing a glimpse into the life and adventures that await her new owners. All of these details you are able to request from me via email.

If Seabear’s story calls to you, or if you have any questions, don’t hesitate to contact me.

Fair winds, Julien

Calculations

Hull Speed
12.2 kn
Classic: 8.51 kn

Hull Speed

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Formula

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

A more accurate formula devised by Dave Gerr in The Propeller Handbook replaces the Speed/Length ratio constant of 1.34 with a calculation based on the Displacement/Length ratio.

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio.311
Hull Speed = Max Speed/Length ratio x √LWL

12.18 knots
Classic formula: 8.51 knots
Sail Area/Displacement
20.4
>20: high performance

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

Formula

SA/D = SA ÷ (D ÷ 64)2/3

  • SA: Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
  • D: Displacement in pounds.
20.35
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
?

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Formula

Ballast / Displacement * 100

?
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
109.2
100-200: light

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

Formula

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

  • D: Displacement of the boat in pounds.
  • LWL: Waterline length in feet
109.24
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
8.5
<20: lightweight racing boat

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Formula

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam1.33)

  • D: Displacement of the boat in pounds
  • LWL: Waterline length in feet
  • LOA: Length overall in feet
  • Beam: Width of boat at the widest point in feet
8.51
<20: lightweight racing boat
20-30: coastal cruiser
30-40: moderate bluewater cruising boat
40-50: heavy bluewater boat
>50: extremely heavy bluewater boat
Capsize Screening
3.9
>2.0: better suited for coastal cruising

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

Formula

CSV = Beam ÷ ³√(D / 64)

  • Beam: Width of boat at the widest point in feet
  • D: Displacement of the boat in pounds
3.9
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

When first introduced the LAGOON 420 was advertised as ‘the first series-produced sailboat with diesel-electric drives as standard equipment’.
A number of layouts available with owner or charter versions.
Offered for sale/charter from the Moorings company.
An updated version is the LAGOON 421, equipped with the more conventional twin diesel power.
Replaced with a new (2015) LAGOON 42. (listed here as LAGOON 42-2).
