Hi Guys
My front aluminium beam has cracked on the upper side, 3 inches in from the starboard front post. I've been advised to take it to an aluminium welder to repair as a new one will be too costly (especially as I'm a student). I have found a aluminium welder who says I can bring the boat in and he'll weld it outside on the trailor. This sounds greats as now I don't have to worry about how to get the beam off as it looks like I would have to dismantle most of boat which scares me. If I take the boat in on the trailor would I not just have to take off the tramp and jib travelor? What precautions should be taken with the dolfin striker? It looks as though the crack would close a bit if this tension was released... If it is recommended to take the boat appart and just take the beam, how is this done? The welder has worked on Hobies before, but is there anything I should make sure he does?
Thanks for any advise...Clint

Welding is questionable. They end up cracking at the weld. We had a guy who had his corner castings tack welded to the crossbar for stiffness... broke the crossbar (at the weld). There is a lot of twist in this part. A weld likely concentrates the forces as it would not give at the same rate.

A replacement crossbar extrusion runs $234.70 including a new mast step casting. Would have the integrated traveler tracks too.

I've had the same experience as Matt. My first hobie was welded on this part. It ended up breaking at the weld, and I ended up in a pile of boat... The mast ended up going through one of the hulls, and the sails ended up ripped. The boat ended up as spare parts, so the cost of a new crossbar is a bargain, especailly if it fails where you may not be able to get help.

Thanks for the advice guys. I'll start looking for a replacement. Maybe I can find someone who has an old one from a broken boat. I might have to go the welding route just to get onto the water for the next month (before replacing) as parts aren't easy (or cheap) to get hold of in South Africa...or stay out of the water
