Sailonet proposes 2 types of mainsails for which the difference is mainly the layout of the battens:
It is possible to fit either sail whether your yacht is a momnohull or a multihull:
- Classic mainsail:
It is the most common mainsail, with a tight fitted batten at the head and 3 loose battens for which the lengths vary depending on the sail triangulation.
- Fullbatten mainsail:
For this type of mainsail,every batten is fitted full length from the luff to the leech.The layout and the number of battens also depend on the sail triangulation and the type of yacht.
On a monohull, the fullbatten mainsail permits to have a slightly larger sail surface compared with a classic mainsail.
The mainsails are fitted with a loose foot as standard, that means (The foot does not fit in the track on top of the boom). This configuration doesn't affect the way the sail works. When you take a reef in,the sail has exactly the same configuration as a loose foot mainsail.
The clew is linked to the boom by a velcro strap. This stops any friction between the boom and the clew. It is easier to tune your sail according to your sailing program.
Common vocabulary used for these 2 type of sails:
- Radial cut
- Laminate material;made of several layers(taffetas/ mylar/ grid / mylar/ taffetas) in one or two basic adapted weight (depending of surface) and following the manufacturer's specifications
- Assembled with UV treated threads
- 2 reefs as standard ( optional 3rd reef)
- Reinforced patches on foot,tack and head.Ever patch has a shape of a "star". Each one of these patches is orientated in the effort requested.
- Aluminium headboard fitted with stainless steel eyelets.or custom headboard ( depending on yacht size)
- Leech line accessible to every reef.
- Loose foot with foot line, strapped at clew.
- Drive stripes,tell tails,bag
The battening of the sail and the slides vary accordingly to the type of yacht and its size.
Battens on a classic mainsail:
- Flat battens
- 1 batten sewned in a batten pocket (top of sail) and 3 loose battens.
- The tension is obtained by a "push-batten" system.
- Nylon slides adapted to the mast.( standard fitting)
Battening for a monohull fullbatten mainsail (up to 45 foot):
- 4,5 or 6 flat battens, depending of the length of the luff.
- Batten pockets sewned to one end (on leech)
- Luff fitted with Sailman or equivalent batten boxes, Drilled to a diameter of 10mm to allow the fitting of a threaded rod
- Fitted with low friction Sailman or equivalent batten slides and headboard
- Intermediary nylon slides adapted to the mast, and attached to the mainsail by elastics.(standard fitting)
Battening for a multihull fullbatten mainsail
- 4,5 or 6 flat battens, depending of the length of the luff
- Polyester strap sewned on the batten pockets to reinforce and avoid friction on the stays.
- Luff fitted with Sailman or equivalent batten boxes, Drilled to a diameter of 10mm to allow the fitting of a threaded rod
- Fitted with SDA or equivalent batten boxes on the leech, and screw tension system to ajust the pressure on the battens.
- Fitted with low friction Sailman or equivalent batten slides and headboard (available depending on the size of the yacht.)
- Intermediary nylon slides adapted to the mast, and attached to the mainsail by elastics.(standard fitting)
For Fullbatten mainsails, the optional Rudgerson slides are available. These slides reduce the pressure put by the battens on the mast and ease the hoisting of the mainsail.
