You can go a long way towards helping yourself before you call in a rigger.
Google up the specifications for the
boat - here:
HANS CHRISTIAN 41 sailboat specifications and details on sailboatdata.com
Print out the page. On the p/o draw a line, perpendicular to the
water line from the after side of the truck down to the
deck. Measure the distance from the aft side of the mast to the point where that line intersects the desk. Two ways to find that distance in inches, but we can come back to that later. Even in cm.s. Or since you are in
Spain, in mm.s :-)
While lying alongside, release your main
halyard from the
head of the mainsl and hang something - anything - heavy on its end. Note where it does, or would, touch the
deck. Now, with your bobstay slack, rake your mast using the back- and jib-stays till the intercept is where the drawing sez it should be. The
jib stay is the one that goes from the truck to the sprit. The stay from the hounds to the stemhead is the fore-stay. Leave it slack for now. Tension is unimportant at this stage. You only need to snug up so the truck is in the right position fore'n'aft.
Now do the same with the upper shrouds. The objective is the get the truck positioned directly over the centre line. Again, tension is unimportant. Your truck should now be good fore'n'aft and thwartships. But there is no
compression load on the mast, and the sprit's fore-end is where it is in the up'n'down direction. There is no
compression on the sprit either. Now snug up the bobstay. All the "strings" except the lower shrouds and the fore-stay are now snug, and no more. Then snug up the lowers and the fore-stay, and you mast will now be where the
designer meant it to be.
Tension is a whole different matter, but the HC is not a
racing boat, so you needn't get all harsh about tensioning the strings. Your objective from here on is to get enuff tension on each string that three objectives are met: 1) that there is no wiggle in your mast when bare, 2) that no wiggle is introduced by the loads imposed when under sail and 3) that the
rigging is not subjected to shock loads as as "loose" rig would be when under sail and in a seaway. Once you are at that point, you can begin to refine the tensions. You do that while under sail. Brian Toss' discourses will tell you how to do that, as will a number of members of this forum :-). But bear in mind that the LEAST tension that meets the objective is the "correct" tension.
