Cariboni's experience in canting keel systems dates back to 1996, when Junoplano was designed. Since then the concept has been continuously developed with different options (one or two cylinders) and additional features (canting and lifting systems). Special attention has been paid to reliability, serviceability and weight savings. The most reliable configuration uses two double acting cylinders: in case for boat of a cylinder failure, the system can continue to be operated using the other cylinder.
The aluminium transverse structure is designed to bear all the stresses generated by the cylinders, and to transfer to the boat structure only the righting moment through the bearings for boats (#7 & #8, these are widely spaced to reduce forces to the minimum). The longitudinal beams (#2 & #3) are
primarily to avoid the structure collapsing in case of grounding. Both the cylinder bearings (#7, 7075 aluminium alloy, or 17-4-PH SS, or Titanium) and the keel pin bearings (#8, 17-4-PH SS) are self-aligning, to allow for minimum misalignment or displacement during sailing.
Small size lifting system: specially developed for small yachts, considering above all the costs saving. The lifting device can be purchased separately by the keel fin and the bulb.

The full lifting carbon/steel daggerboard of the large yacht SYL 44 m Frers design, built by Barcos Deportivos, is delivered finished in full and ready to be bolted easily and quickly onto the hull.
