Yo,

I am building a frankenboat F18 using the beams and hulls of my 5.5. Also have a cut down Marstrom Tornado ally mast where all fittings will be taken from the 5.5 mast, a 02-05 Nacra F18 mainsail and an Infusion jib. The mast profiles of the Nacra 5.5 and Marstrom are not very far even if the Nacra is somewhat shorter. So the fittings will fit.

To see if the jib will fit I need to know tack height (or intersection of bridle and forestay wire) measured from deck level. and distance from front beam to bridle fitting on hull.

Anyone here who could possibly help?

If someone also have the measures of where all fittings are placed on a 02-05 Nacra F18 mast I would be delighted.

Brgds
Lars
