I am looking at replacing the I-Beam in my H-30. Was wondering if I can slacked off the rig, use jacks and 4x4 to take the load off the I-Beam and then replace it, or if I have to destep the mast? Also is it possible to get a stainless steel I-Beam, if so where from? thanks

Great pictures! Post Material?
Patrick - talk about a complete answer for the question! O2Addict, check the archive for discussion on the best material for the new post's core. I hope that the epoxy costing is good, because impregnated wood was not recommended due to the nasty compounds it will outgas over time. Pine does not have a lot of dimensional stability under stress and over time. I believe that JC II recommended spruce, but do check the archives, since my memory is suspect. David Lady Lillie

Mine's Metal
I searched the archives, but found no reference to the metal post in the H30s, except comments about them rusting, and one about replacing it with SS which I assume is Stainless. Can I use wood instead of the iron ibeam?

Hey Dave
Pressure treated fir has been used for over 20 years to hold up hundreds of thousand home decks all over this country. I think it will keep my mast up for a while. Your right about pine under stress/tension (vertical load) this is a horizontal load (compression) and its fir (denser).

The link below is JC II's comment on this subject last year. Impregnated wood is used in decks and other outdoors applications because the poison in the wood really does preserve it longer against insect damage, and is born away in trace amounts as it outgasses. There is about zero potential damage from insects in the interior of a boat, and the outgassed poisons will be trapped in the cabin as the boat is left between cruises, or while buttoned up in nasty weather. I'm not a wood expert, so I don't know about the dimensional stability of fir. The dimensional stability requirements and loading on a deck are far less than the multi-ton load on your compression post when the shrouds are tensioned. By the way, JC II designed much of the h 30 interior for his dad, giving him some real background on this issue. David Lady Lillie
