How do you read a polar sailboat diagram?

Polar plots are published by each manufacturer for each model of boat with their various sail plans. It’s easy to read – move your finger radially along any true wind angle. Stop when you reach the boat performance line associated with the true wind speed you are experiencing.

Can a Lagoon 380 cross oceans?

The Lagoon 380 is a proven ocean crosser. She’s a sturdy, safe little boat that saw off the Lagoon 39 (also no longer in production) and continues to attract fans. She holds her value pretty well on the 2nd hand market too – quite a feat when you think of how many 380s are out there.

Are Lagoon catamarans safe?

They’re Safe Lagoon cats are all well thought out for safety considerations, with handrails all over the place for safe movements even in bad weather conditions. The decks are wide and clutter-free, and the running rigging is suitable for short-handed sailing.

What are sailing polars?

Polars are a way of presenting boat speed vs true wind angle at a variety of true wind speeds that help you determine the fastest point of sail. They are called polars because they are a plot of boat speed and true wind angle on what is called a polar plot.

What are polar diagrams used for?

Polar charts are data visualizations best used for displaying multivariate observations with an arbitrary number of variables in the form of a two-dimensional chart. Polar charts are also known as radar charts, web charts, spider charts, and star charts, among many others.

What is the purpose of polar diagrams?

Polar, or `Radar’ charts are a form of graph that allows a visual comparison between several quantitative or qualitative aspects of a situation, or when charts are drawn for several situations using the same axes (poles), a visual comparison between the situations may be made.

How fast is a Lagoon 380?

between seven and eight knots
The 380 will motor between seven and eight knots at a cruising RPM of 2500, depending on wind and waves. Upwind sailing in a breeze less than 10 knots will not set any records and pointing is a bit compromised as the Lagoon has no daggerboards to keep it tracking.

Is Lagoon catamaran blue water?

The best production blue water cruising catamarans are the Manta 42, the Lagoon 42, the Leopard 45, the Lagoon 450, and the Prout 45. These vessels have excellent living accommodations and great sea keeping abilities.

What does a polar plot tell you?

Polar plot is a plot which can be drawn between magnitude and phase. Here, the magnitudes are represented by normal values only. The Polar plot is a plot, which can be drawn between the magnitude and the phase angle of G(jω)H(jω) by varying ω from zero to ∞. The polar graph sheet is shown in the following figure.

How do you plot a polar plot?

Plotting polar coordinates example

Locate the angle on the polar coordinate plane. Refer to the figure to find the angle:
Determine where the radius intersects the angle. Because the radius is 2 (r = 2), you start at the pole and move out 2 spots in the direction of the angle.
Plot the given point.

Is the Lagoon 380 a good sailing boat?

Because the 380 is such a popular boat, there are quite a few good sailing blogs out there which are useful if you want to get a better feel for the catamaran. A good one is Sailing on the Sunnyside which all about a couple living the minimalist life on their 380: Sunnyside.

When did the Lagoon 380 S2 Come Out?

For example, Hull #35 (Serenity Now) was built in 2000, still almost 1000 hulls off the final production run tally. Barit is hull number 509, launched 2008. The main upgrade (although owners of the original design would probably say it was a downgrade) was with the launch of the Lagoon 380 S2 in 2003.

What happens to a lagoon catamaran at 45 degrees?

At 45 degrees, the speed drops off and the leeway picks up. The quality of the interior finish is acceptable but it doesn’t wear that well. Many of the older boats still have the soft top bimini. Lagoon 380s do suffer from hobby horsing.

When was the lagoon catamaran built in France?

Last update: 2nd April 2020 The Lagoon 380 is a 37’11” (11.55m) cruising catamaran designed by VPLP Design (France). She was built between 1999 and 2008 by Lagoon (France) with 548 hulls completed. Lagoon 380’s main features
