The top down sets include the bottom-up drum and swivel, torsional stay and top-down tack adapter. This set is ideal for use with Code 1-6, reacher, runner or gennaker sails when used as a top-down furler, or when combined with an anti-torsional stay the drum and swivel can be used with Code Zero, screecher and stay sails for use as a bottom-up furler.

Differently from the previous Bamar Rollgen model, in the new RLG EVO, the tack swivel (fundamental element when furling free flying sails) is independent from the drum. In fact, it is now integral part of the special ROLLGEN stay.

RollGen is the special patented stay that may furl Gennakers and less specifically all sails with free flying luff.

The stay is made of a special anti-torsion stay that may transmit the furling torque to the sail head (top-down furling system0. It is covered by a special EPDM gaiter that absorbs compression stress that would weigh down upon the sail cloth. Furthermore, the gaiter allows for the sail to furl on a bigger diameter compared to the naked stay. While furling out, it allows the sail to unroll at different speeds, since it absorbs stress that would weigh upon the sail and would make the furling out operation not correct or impossible. These elements make of RollGen a unique and patented furler that is different from other existing systems that are only apparently similar systems.

The standard RollGen anti-torsion stay (08,10 and 20) is made of unidirectional special fibres realized in kits with maximum lengths and different sizes. For RLG EVO 10 and 20, longer lengths can be produced using a special 3K torsional stay (10 3K and 20 3K) made with inextensible material in order to enhance its torsional capacity. In any case, ths stay supplied can be easily adapted to the measure taken onboard. The measuring and cutting operation is very simply done with the use of simple tools that are included in the kit.

After having furled the Gennaker on the special RollGen stay, you may disconnect drum and halyard swivel by means of quick release pins. These may be thus used in order to furl other sails, such as Code 0 or Drifters.
