Flying Sail on Freedom 32 sailboat

From the sail owner:

We used the G-spin AKA “big red sail” on segment from Anacortes to Bellingham coming home. Made 3 hour continuous, port tack, broad reach in only 4 to 8 kts of wind maintaining 2.8 to 4 nm/hour. Was amazing light air performance for that sail coupled with the main; and was the longest continuous tack and perhaps the most physically pleasant extended period of sailing I’ve known on the MM. the word idyllic comes to mind.

Making 3.2 knots in 5 knots of real wind. Did the maiden crossing of the Straits of Juan De Fuca today. 40 nautical miles of beating into the wind against
1 to 2 knots of current and still managing average of 5 knots per hour. Thanks again for your advice.

Dimension Sailcloth Racing Sail

This is a picture of a racing main with square top and a laminate racing Genoa on a J 32 Sailboat. These sails are both new and currently racing. Both sails are made with Dimension Sailcloth.

Hand sewn eyes for sails

First picture shows the eye and how the brass ring is stitched around the eye, next showing the finished covered brass eye ready for the thimble that is pressed inside the brass ring. This is a technique that goes back many years before the use of stainless pressed eyes for sails. It is an old traditional technique that is still requested by some for traditional and classic sails.

What are the characteristics of a good furling genoa?

The cloth for the jib or genoa should be the correct weight for the boat and rig. The panels and seams should be strong enough to handle strong winds and also be useful in light air. To be a good reefing sail, the patches should be deep to handle a wide wind range.The headsail must fit and complement the furling unit so the sail is functional when reefed.

A foam luff is very important for reefing.  It can flatten the sail when the wind is strong and still keep the boat upright and moving in big waves and strong wind.

Radial vs. Crosscut:  Most have their sails built crosscut using woven Dacron to keep the cost down.

Radial designs are more expensive to build, but much stronger and more suited for a wider wind range. With some radial designs you can mix the weights of sail cloth to make the sail a true multipurpose genoa. The clew should be a at a good angle to help sheeting the sail when reefed.

The UV cover for the leech and foot should be deep enough to cover when furled.  I place the UV cover after the sail is finished so the UV can be changed quickly when needed.

When we build our furling sails,  for mains or headsails, all of the key details are placed in the design, and the finished sail.

Bi Radial G-Spinn for North Idaho College

We just received this picture from North Idaho College. This is one of the small G-Spinns built in a Bi-Radial design. It shows how the sail is being used to make sailing easier. It is made with 1.54 oz. nylon, has a spinnaker sock to make it easier to use. This is the sailing instructor for North Idaho College.
