Gennaker for 44

Has somebody a gennaker in 44? Liked to know the measures of SLU, SLE, AMG. Good propositions/solutions on the deck how to use the spinnaker boom to extend the 0,33 x J tack point will  be taken in to consideration ...

Dear SAFA

Are you proposing to use the spinnaker pole as gennaker bowsprit with a length of 0.33 x J? This is not a good idea, the pole can not take such a load if original aluminium.
If you have a 100 mm pole it can extend 0.47 m forward of the support point, and if it is a 120 mm pole it can extend 0.69 m forward.
Kind regards
Lars

Thanks for Your answer. I  was thinking the Scandinavian LYS handicap system where the tack point for gennaker can be this 0,33 x J - if someday sail home with SAFA. Our booms are 120 mm aluminium. But if the coatpipe over the boom, attached to the bow, inox steel, is long enough (ex. 200 mm) then maybe  it could last he pressure?

Dear SAFA

Pls note that 0.33 x J means 1.87 m length. It appears that you suggest a 0.2 m addition to the recommended 0.69 m, this is not enough.
Can be commented that a bowsprit with such a length will be rather heavy.
Kind regards
