Measure the distance from the transom to the aft edge of the mast. The spar should stand at 90° to the mast gate (just for this measurement!), and you should include the mainsail track, as if it came all the way down where it's actually cut off now below the boom. The reading should be about 3095 millimetres. Chances are that the mast foot is farther back (smaller number) than that now. This is also part of the basic tuning; your sails may be some very old cut which may have used settings very different from the modern ones, but I still think that is the best figure to use as a starting point.
Your mast is an Elvström, which has the sail track cut away below the boom. The measurement is done as if the track continued all the way down (it's a class rule), so you need to subtract the track depth from the measured transom-to-mast distance.I get the measurement from the transom to the aft part of the mast (3095mm), but what does the main sail track have to do with the measurement?
If you absolutely want toam I sticking a nice, big carpenter's square on the deck to check that the mast is perpendicular?
Cool! Have you thought about keeping the vintage single-car system vs. changing to a bridle? (The track has to be there even if there's nothing "travelling" on it.)I got my new Ronstan I beam from APS and took the old bent one out (I can't imagine how that got bent!). I now have to cut it to length and drill some new holes in the correct spots but the beam shape does fit, thankfully.

There are plenty of hiking straps on the market, but they're not necessarily a good fit for your boat or worth their price. I could link to Zhik or Mackay but I feel that would be somewhat beside the point. Are you going to keep the buckles on the floor stringers in front of the traveller? It might be then smartest to get some generic "seat belt" -type strap, and sew loops at the aft end for rope attachment. (The forward ends of today's straps are meant to be attached directly to the traveller track.)Does anyone have any suggestions for where to source out a set of straps? I'd like a set for the skipper and crew positions.
Good material (polycarbonate), but more than twice the thickness that you really need. The flaps are just meant to keep the water out, after allI have some nice, thick (1/2") lexan pieces kicking around the shop.
They are probably very close to identical. (I don't even see a badge.)Will a set of 420 bags do the trick? They look the same, other than the 420 badge.
