Spinnaker boom length
Postat: 01 jun 2022 17:49
2530 mm according to class rules, measured all out according to conventions (not explicit, I think, in this case)
But: the original Proctor (AKA Selden) serial nr 534012 spinnaker book makes 2530 with the original spinnaker boom ends measured at the center of the cleat cavity, not all out: if measured all out it is (45x2)+2455= 2545, if measured at the center of the cleat where the ropes pass, (37.5x2)+2455=2530 mm.
Now the old endings are obsolete as they absolutely do not allow the opening to the top (safer in removing the boom).
The new endings that allow both directions of use are 15 mm longer. In fact there is one model that is only 45 like the original ones and not 60 mm long, difficult to find.
Now, before seen cut and adapting all the Selden spinnaker booms sold so far (and in particular mine) I'd like to rise again the question on the total length, way to measure and type of endings.
Thanks for the attention
