about beams curvature

[adriano meis]

ciao everybody

I'm going to rebuild the mastbeam, because the old one is definitly rotten.

I'm actualy copying the original one, because I bought my TIKI26 and I did not build it.

now:

I realized the bottom part of the beam is not exactly linear but looks like bent, curved. The mastbeam has a lens shape.

Is this because of the pressure of the mast on the center of the baeam? is it deformed under stress of the mast OR should I build thenew beam respecting this shape?

I can post some pictures, maybe it's better

grazie a tutti

Hi Adriano,

The apex of the curve should be up. . .Does your existing beam have the dolphin striker, with the wire cable?

[adriano meis]

the apex of the curve IS up and the beam had dolphin striker with wire cable.

the bow beam on the opposite has a apex curve down.

so  have I to respect this shape? mmh.... it's little bit more difficult

I try to post some pictures

Hey Adriano,

Both Mast and aft beams have a flat bottom with a curved top and fairing. Fwd beam has a curved bottom and as Kym mentioned Mast beam has a wire dolphin striker.

I'm sure Wharram would avail drawings to you, even if for a fee.

Enjoy the build, I did.
