Designed over 40 years ago as a mini-scow ("scow" refers to the shape of the hull), it has, like the other, larger scows, withstood the test of time and is still one of the very best small 1 to 2-person boats available. More comfortable to sail, with fewer specialized parts and pieces, and easy to sail, have made it one of the great simple designs of all time.

With plenty of room for 2, its a great kids boat to learn on and to develope skills to advanced levels - or to just have fun on the lake. For adults, it is easy to get comfortable in - one of the major problems with most boat this size - thanks to the deeper and roomier cockpit so you don't have to sail with you knees under you jaw. Iit is easy enough to sail that learning takes place fast.

And if racing is the goal, this boat shares with the other bigger scows the tradition of women sailing equally with men, but adds on it by making it possible for kids to sail equally with adults - all because there are no gimmicks or gadgets or special skills beyond simply being able to sail well.

With close to 11,000 built, this boat has succeeded in the marketplace by being a success on the water.

Its the ideal, simple, one-person recreational racing boat, or two-kid youth play, learn, or race boat.

C ontact us for availability and current pricing.

You might want to check out our Gear-->Dollies page.

We also offer Jim's own tiller extension , the right length, and with the right swivel connector that doesn't flip the extension away from you if you happen to let go. It is $60, you can find it on the Butterfly-->Parts page, which lists the Butterfly parts we normally stock.

Butterfly is a 12 ′ 2 ″ / 3.7 m monohull sailboat designed by John Barnett and built by Windward Boatworks and Barnett Boats starting in 1961.

Rig and Sails

Auxilary power, accomodations, calculations.

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.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

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

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.

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.

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.

Ballast / Displacement * 100

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.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

  • D: Displacement of the boat in pounds.
  • LWL: Waterline length in feet

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.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

  • D: Displacement of the boat in pounds
  • LOA: Length overall in feet
  • Beam: Width of boat at the widest point in feet

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.

CSV = Beam ÷ ³√(D / 64)

A Brief History of Saint Petersburg’s Scarlet Sails Festival

butterfly sailboat sails

A romantic festival, created to celebrate youth and congratulate school graduates on the beginning of their adult life journey, is now considered to be one of the best festivals in the world, attracting thousands of people every year from Russia and abroad. We are speaking about the famous Scarlet Sails Festival, and here is the history behind it.

First started in June 1968, the concept of the festival is based on the fairy tale by Alexander Green, Scarlet Sails . The romantic spirit, celebrating love, dreams and hope, was there from the beginning and still remains as the basis of the festival. The first edition of Scarlet Sails was attended by around 25,000 school graduates and became a hit, which set a tradition to organize the festival every June, during white nights. However, in 1979, the celebration was suspended, and returned only in 2005.

Nowadays, the festival organization is divided into two parts: it starts with a big concert on Dvortsovaya Square, followed by the spectacular show on the Neva River. Although the entrance to Dvortsovaya is invitation-only for school graduates, there is usually another stage on Vasilievsky Island where all other guests can join the concert while waiting for the main part of the festival.

The light and water show usually starts after midnight and is held on Neva River between Dvortsovyi Bridge, Peter and Paul Fortress and the Hermitage . Spectators can watch the show from the banks of the Neva River and bridges.

The spectacular show lasts for about 20-30 minutes and involves an impressive range of elements: pyrotechnics, light, orchestra, water show and, of course, the culmination is the appearance of a beautiful ship under scarlet sails. All elements are synchronized with the music and with each other, so the crew of the ship is under a tremendous pressure to make sure the ship passes every milestone exactly on the precise second when it is planned to happen.

Nowadays, there are just a few ships that exist in the world that can manage the task of being a live symbol of Scarlet Sails Festival. From 2009, the ship under scarlet sails is the Swedish “Tre Kronor.” The sails are produced following traditional marine sail technology, the only difference being that the ones for the festival are a bit thinner than the real ones you would use to sail the sea.

Every year, Scarlet Sails attracts between 1.5 to 3 million guests to the center of St Petersburg, to see one of the best city events of the year. From being a local celebration, the festival transformed into an international event, being shortlisted in several nominations of “ Best European Event Award ” and becoming a winner in the “Best City Event” category.

If you are planning your trip to St Petersburg around 15-25 June, make sure to check when the Scarlet Sails is being held. In 2018, it will be held on June 23. Once at the festival, bring some warm clothes as it still gets quite chilly at night in June, and come to the Neva embarkment quite early if you want to find a good spot – it gets really crowded.
