The Tri-Furl Genoa
The Haarstick Tri-Furl Genoa is designed and built with one thing in mind: performance! Here are the details of how a Tri-Furl Genoa from Haarstick will out-perform any other roller-furling headsail on the market...at any price!
Construction:
Tri-radial; Split-Weight. The Tri-Furl Genoa is a reflection of
our racing genoas: Tri-radial handles the high loading in the
corners of the sail with catenary engineering along the leech
where the loads are highest. In addition to radial and vertical
seams, horizontal seams are used for precise aerodynamic shaping
of the sail. The result is an easily trimmed, no-fuss sail that
leaves you more time to enjoy the cruise.
Another feature of the Tri-Furl Genoa is Split-Weight construction. All Tri-Furls incorporate multiple types of fabric. The heavier fabrics are used in the leech and foot of the sail where the loads are highest. In the sail's fore body, where loads are diminished, lighter cloth is used. This keeps the sail's weight to a minimum providing easier handling, better light air performance and enhanced durability.
Ultra-Violet Protection: UV protection on the leech and foot is a standard feature of the Tri-Furl Genoa. Several types of UV. protectant fabrics are available. Your Haarstick sailmaker can provide you with specific information to help you decide which is best for your needs.
"Reef Down Patches": Extra reinforcement layers in the head and tack distribute the loads into the body of the sail when the Tri-Furl is partially furled or "reefed." These reinforcements prevent the leech and foot from being overloaded and becoming distorted, a function traditional acrylic covers simply cannot perform. In addition to these "reef-down" patches, we install reduction marks to let you know how much you have reduced sail area and when you are reaching the practical limit of reefed performance.
Luff Flattening Devices: For improved performance in heavier conditions when reefed we recommend the "SEAFORM" foam padded luff option. This draws excess fullness from the mid-section of the sail as it rolls around the headstay making the sail flatter and draft-forward. Consult with your Haarstick sailmaker for details.
The Tri-Furl Genoa has an upper wind range of 30 knots apparent, which encompasses all average sailing conditions. However, we strongly recommend that you have aboard a heavy-air or storm jib, of suitable weight and construction. The list of possible problems at sea is end less and it is only prudent to have a back-up sail.
No other sailmaker has as many years experience producing vertically and radially oriented genoas as Haarstick. Now cruising sailors can benefit from this experience with a sail built for their special needs -- The Tri-Furl Genoa. It is absolutely the best engineered roller-furling genoa on the market.
