Weer zo'n jaloers makend lekker filmpje, Le voyage de Kiwi, zeilen zoals het zeilen bedoeld is.
Opvallend dat die boot een rolrif in het grootzeil heeft. Ik dacht dat dit systeem al jaren uitgestorven was, omdat een gereefd zeil er eigenlijk nooit mooi op staat. Ook dit grootzeil heeft de nodige rimpels richting de top, omdat het onderlijk tijdens het rollen niet strak wordt gehouden.
In ieder geval zit de gang er wel goed in.
Het lijkt ouderwets maar Ian Farrier past het rolreef zelfs op zijn meest recente ontwerpen toe, zelfs zonder giek. Ik ben ook geen liefhebber maar moet wel toegeven en in de praktijk ondervonden dat het goed en eenvoudig werkt. Ter lering en misschien vermaak onderstaande quote uit de Sailing Manual
(zijn er nog andere ontwerpers die een sailing manual mee leveren, of een tips&tricks brochure, een document "buying second hand" waarin aandacht voor de zwakke punten van de boten uit de verschillende perioden en nog vele andere bulletins op het gebied van gebruik, onderhoud, reoaraties, zeewaardigheid, etc.. Ik heb inmiddels wel bewondering voor deze Willie Wortel Ian Farrier gekregen)
REEFING
Several different reefing systems can be fitted, and all the control methods are well documented. The roller reefing boom as used on the F-28 and optional for the F-31 is a very effective reefing system, being fast, easy to operate, and infinitely adjustable. It’s other main advantage is the ability to easily roll up the mainsail for storage.
To reef, first disconnect the boom vang (if fitted) and Cunningham eye tackle. The topping lift should also now be used to lift the back of the boom a couple of inches above horizontal. This stops the main from creeping forward to bind against the mast when furling. This may not be required, depending on the cut of the mainsail. Now take the main halyard around the winch and release the rope clutch. Go forward with the halyard held in hand, unlock the furling handle and begin turning. As the main is rolled down, let the halyard slowly run out to suit. When the main is rolled up sufficiently, lock the furling handle, let off the topping lift, return to the cockpit and retension the halyard. Reefing is complete. You should always try to locate the head of the reefed mainsail close to or just above a staying point, rather than in the middle of a mast panel. This avoids unwanted bending loads on any unsupported mast section. As mentioned previously, if you find a problem with the mainsail rolling up close to and jamming against the mast, this is usually caused by not lifting the end of the boom sufficiently with the topping lift. You may also find it easier to regulate the speed at which the halyard runs out, as you wind the boom, by using the ball of your foot on the line just before it enters the mast. The boom vang cannot be reconnected, but with the barber hauler system available, if needed, from the floats, this is not of any importance.
A Jiffy reefing system may also be fitted, in addition to the roller furling boom, and this can give slightly better sail control for better sailing efficiency. To use, simply roller reef as described above, but only roll the main up until the selected jiffy reefing points are reached (two sets usually included as standard). Lock the furling handle as before, and then reattach the Cunningham eye tackle to the reefing tack eye. Now unthread the outhaul line and rethread it through the new reefing clew eye. All the controls of a jiffy reefing system are now in place, except you don’t have to tie off the sail it being already neatly rolled around the boom! It is advisable to take a line from the Cunningham eye forward and around the mast. This avoids the possibility of the bolt rope pulling out of the mast groove.
