Seller's Description

With the Lagoon 380, Lagoon designers have met an impressive goal of more interior volume, more comfort, more speed and a driving emphasis on aesthetics without compromising safety and sea going capability. More interior volume - the new vertical window design provides headroom and visiblity all the way foward. More comfort - great livability design features a breakfast bar linking the cockpit and the galley, an office desk and a large, separate shower. More speed - designers incorporated trickle-down technology from racing multihulls. Safety - the sail control lines are led back to the helm. Sea going capability - her construction meets European Category A open ocean standards. She is also fun and easy to sail.

The Story ofTirNanOg

TirNanOg is the Celtic land of eternal youth where time spent there is added to your life instead of subtracted. We have enjoyed sailing TirNanOg around the Caribbean where we were based in Blue Lagoon in the Grenadines for many years until we brought her back to the USA four years ago on the Salty Dawg Rally from Antigua to the Chesapeake. Since then we have sailed her to the Bahamas and Florida for the winters and back to the Chesapeake and the New Jersey coast for the summers. We have worked on keeping TirNanOg in top shape since we purchased her new in 2003 and have been the only owners. Over the last several years we’ve made major improvements to TirNanOg to keep her a very safe bluewater sailboat. Among the recent improvements are the following: Brand New Yanmar 3YM 30 29 hp engines and SD 25 Saildrives installed by Bayshore Marine in 2019 currently with under 500 hours. Other recent improvements are as follows: new square top main sail for better speed and upwind performance, new Bimini, new Profurl oversized jib furler, new Isotherm Low energy ASU refrigerator freezer, new stove with oven and broiler, new BBQ, new 1060 amp house battery bank with all new main wiring and Victron Connect controls, new Gori folding props, four new 2000 GPH bilge pumps located in bilges and engine compartments, new microwave and new Navionics helm plotter with AIS transceiver. Also, among other features of TirNanOg to help with blue water sailing and exploring beautiful remote areas are 480 watts of solar panels that generate approximately 200 amps of domestic power per day, two 300 litre domestic water tanks, and a built-in 2000 watt 120 volt inverter. Also included is a spare 55 LB Rocna anchor with an additional 200 ft of 3/8 inch high tensile chain with a 12 ton swivel and a mooring ball to be able to more safely long term anchor in remote areas. Also included is a 10.5 foot Walker Bay dinghy with 9.8 hp two-stroke Tohatsu outboard with protective Sunbrella cover.

TirNanOg has done several long-distance rallies including the Caribbean 1500 in 2008 and the Salty Dawg rally from Antigua to the USA in 2017 and the Salty Dawg Rally to the Bahamas in 2019 and is a reliable Bluewater boat.

Calculations

Hull Speed
10.4 kn
Classic: 8.05 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

10.4 knots
Classic formula: 8.05 knots
Sail Area/Displacement
20.9
>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.
20.89
<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
152.0
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
152.02
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
11.3
<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
11.31
<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
3.4
>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
3.4
<2: better suited for ocean passages
>2: better suited for coastal cruising
