LIBERTY

At the begging of this project, we had considered to allow mixture of each size of MASTs. In fact, 100%, 80% and 55% in various lenght could be combined each other. In typical MAST, windsurfer is unable to adjust flexibilty of MAST by his/her physical condition. Adujust only with downhaul and outhaul tensions are insufficient to get best flexibility for him/her. LIBERTY provides MAST very adaptable way by which is able to choose MAST 15cm or 30cm unit accordingly.

Sail power point should be locked in the bottom area at ideal sail condition. Keep same centroid position even on windflaw and let out unnecessary wind power by flexible twisting bent in the top area. This prevents centroid shifting even in hard condition. It is very hard to maintain this ideal condition by only with downhaul and outhaul adjustment. Also, single size MAST bent curve never fits all windsurfers. To select appropriate MAST which has ideal flexiblity especially in a upper half is inevitable to ensure ideal sailing for each individual windsurfer.

ALL-ROUND setting may bring more top speed. "STRONG WIND & ROUGH" setting, however, could be adequate in case of windsurfer feels sail too hard in a tough condition by flexible MAST. LIBERTY recommends "STRONG WIND & ROUGH" setting on a tough condition especialy for light wight windsurfer or people who is looking for smooth and flexible sail feeling with easy control.

MIDDLE MAST EXTENDER is able to make MAST softer four percent in all three top, middle and bottom part.
To combine different MAST size, ex. 430-bottom plus 400-top, makes 15cm difference compare to use same size in both bottom and top. In addition to this, MAST would have more option with MIDDLE MAST EXTENDER. Variety of top, bottom and MIDDLE MAST EXTENDER combination ensures to find ideal MAST flexibility for each individual on various condition.

In this condition windsurfer may sail like in one's chair. Middle to top MAST twists flexibly as response to wind. Size down top MAST or use MIDDLE MAST EXTENDER increases control in strong wind condition. Of course, it is needless to say bottom part should be stable for preventing power-point, or centroid, shifting.

In general, people increases downhaul tension for over wind condition. Strong downhaul tension makes sail harder by increasing mast bent and sail handling is becomming radical on and off response as a result. "Flexible MAST" could be realized by light downhaul tension. More flexibility brings more control, windsurfer is able to get easy control sail by this manner in some case. I hope you will utilize MIDDLE MAST EXTENDER effectively for getting confortale sailing with "Flexible MAST".
