Iv just read back through this thread , and desided to coment on a few more things,
The Kruger being a ''canoe '' rather than a kayak , with a sea kayak we are restricted by the size of the cocpit and the need to reach our rig, in partiqular the boom when its being stowed away. With a deked canoe thers a bit more room , and I emagin the ability to moove forword to stow a sail easier.
when placing the mast position thers a cupal of things to consider, wher it sits when its stowed, and wher the boom is when its up , I like to position the mast so I get a full high angel stroke in with my paddel ,
the positioning will influwence the sailing performance and caricteristics of the kayak /canoe , but not as much as peopal like to think, (afterall it's a canoe not a performance sailing skiff ! ) I prefer to run side stays and back stay, placing the back stay can be dificalt on an open or decked in canoe , ther are 2 options, run two backstays (4 side stays as previously mentiond ) this is good , the hard thing is geting the tention eaven on the stays. anuther way is to position the saddels asif you wher going to mount 4 stays , between 300 and 400mm behind the mast foot, then run a bridel across the back saddles and tie the back stay into the senter of this bridal , it wont mater if its abit off senterd as the side stays hold the mast position , its not sheard between the two port or two starbord stay .thid bridal can also be yoused to run your main sheet through sa well.
hope this made sence , Im going to make up sume more u tube showing diferant idears shortly .
