Mane

Carbon tape, laid on a flat table along the lines the sail is loaded on. The structure is drawn with the shape, then built to it.

Mane is Lion Sailing's carbon tape construction. There is no bolt of cloth to cut from. The loft lays continuous carbon tape on a flat table, each run placed and angled to follow a load path, then consolidates the whole layout into one sail. Where the head, tack and clew pull hardest, the tape stacks up. Through the lightly loaded body, it thins out.

It sits beside Paneled and Stride. Paneled is cut from cloth and seamed. Stride builds the sail from carbon thread. Mane builds it from tape: wider runs of carbon that stay unbroken from one loaded corner to the next. The loft will say which of the three suits the boat and the program.

HEAD TACK CLEW LEECH

How it's built

Load in a sail is not even. It gathers at the corners and runs along a few lines between them: up the leech from clew to head, down the luff, and across the foot. Mane is built on those lines. The flying shape sets the loads, the loads set the tape layout, and the layout is fixed before anything is consolidated.

Tape
ContinuousEach run goes corner to corner without a break, so the carbon carries load along its length instead of handing it across a seam.
Mixed widthsWide and narrow tapes in one sail, at different angles, stacked deeper where the load is.
On the table
  • AngleEvery tape follows a calculated load path
  • DensityPacked at the corners and leech, thinner in the body
  • CornersReinforcement built in at the head, tack, clew and fittings
  • StiffnessStiff where the shape has to hold, softer where it can give
  • WeightCarbon only where it carries load
Shape

Shape and structure are drawn together, not one after the other. The aerodynamic shape and the tape layout come out of the same design pass, so the structure is part of the sail rather than something added to it.

Put Mane on the boat.

Mane sails are built to order. On the quote form, pick Mane under Construction and send the rig measurements. The racing and offshore programs are the rest of the inventory.
