I have sailed about 4,000 NM on Lagoon400 this summer - here are my 5 cents worth of experience:
1. Very light/light winds 5-10Kn - boat is sluggish. If sea is flat, the boat will start to live at about 8-10Kn. It helps much to use gennaker/code zero if reaching or going downwind in such a light airs.
2. Winds between 10-20Kn - excellent performance in anything between 50deg to 140deg to the true wind. Difficult to run directly downwind, as the shrouds prevent full opening of the mainsail
. If the sea is choppy - beating against the wind at the upper range is unpleasant, the bow pounds.
3. 20-30 kn - the boat still behaves nicely in broad reach and run. Easy to reef (I have reefed singlehanded downwind). Very difficult to beat against the wind. I did sail the boat under engine
in 20-24Kn directly into the wind in a confused sea but with waves of about 3-4 feet only - lot of pounding and spray, but nothing dangerous and you can continue to do anything on board safely.
4. 30-40Kn - We have sailed only downwind in the Biscay and later around cape Finisterre, with 4-5m following waves. Under 3rd reef the boat sailed smoothly and we had drinks in the cockpit
. When you get used to it, it is great fun. All reefing and raising sails
was done downwind! It was frightening to turn into the wind.
In general - the boat speed over water
is about 50% of the apparent wind, up to 10Kn of boat speed.
Beating against the wind, the leeway may be up to 20deg. It depends much on sea state, getting worse as the sea grows.
tracks are positioned very close to the center of the boat. In anything between reaching and running, the genoa
will be happy with a barber hauler or a whisker pole to hold the sail out.
In all kinds of weather the boat felt easy to operate and very safe to move around the decks.
