Spliced Boom

I recently spliced the corroded ends from my main boom and had welded one replacement end (about 9" from both ends-put back a 24" piece) back. Question is--which end should go back on toward the mast (spliced or not), my main sheet is attached to the END of the boom. Boom is aluminum, caps are stainless; boom is about 15 foot with a 40 foot mast. Where is the stress or/and should I sleeve the boom incase of failure. Thanks in advance.

The highest stress point is at the vang attachment. The second highest is at the mast. Even though you attach your sheet at the end of the boom, that is still the lowest stress point (because of the length/arm).

So, You should keep the splices away from the vang attachment and preferably in the aft-section.

cheers,
Nick.
