high strength (H36 ) steel is much preferrable, because steel is very stiff material and any transverse loads (like from the gaff, or a result of slight mast sag to leeward when sailing) easily translate to bending moments in the tube.
Quality certificate, acceptable to well recognized classification society (eg, Lloyd, Germ. Lloyd, Det Norske Veritas) could not be overvalued - it will ensure you are getting REAL THING, not waste water pipe or something.
Certified welders will ensure (to a degree) they do a REAL JOB (with 100% X-ray control of all welds).
I speak from experience -masts to my design are stepped today on 34m schooner. Germanisher Lloyd survey was a great help in quality of final product!
Good luck! |
yes, you are right i'll look any standard pipe that available in Indonesia, because there is no point if you specified something that doesnt exist in here.
this is the sail plan....with the local bowsprit (bugis bowsprit)
