Laerke IOM by Søren Andresen
Søren Andresen (DEN) sent me the plans for his own design with which he won the 2005 Nordic Championship and placed 2nd in 2004. He also sailed it into 35. place in the 2004 Euro Champs in Arcos/Spain.
The PDF file contains the sections and a drawing with the mast and keel positions but you should really download the DXF file and printout accurate sections with a CAD program if you want to build the boat.
Arm winch sheeting arrangement
Søren Andresen (DEN) uses this interesting arm winch setup on his boat.
The idea is that by attaching the jib and mainsheet at different points wrt. the block on the arm you can get unequal travel on the sheets. As shown here the mainsail can be adjusted virtually independently of the jib sheet when close hauled.
A number of people were interested in it at the Euros in Arcos so Søren has made a detailed drawing and kindly allowed me to publish it
