Hi Bernd , to late for the sloop rig , I already have all the carbon For the masts and ?I had sails Made (Rolly Tasker ) plus biplane rig like that is what attracted me to that ?boat . The simplicity of furling Main sails and lack of rigging wires , better stability ?So I have to build those masts , it does not look to difficult , I am up to that challenge . ?You mentioned the tape wetting machine , ? can you please post the drawings ?, didnt get them with the plans . I am ?anticipating the new cabin design . Cheers?
