I think I just realized why Amel didn't use SS pipe for the hawse pipe. I just priced a 31 inch long pice of 316L SS tubing (OD 3 inch with 0.25 inch wall thickness). $10 US per inch or $310 for the piece. Yikes!! a bit of 1/4 into 316L plate brought the total to $375.00. The same in galvanized pipe would probably be $10.
Of course using stainless would alleviate the grief we are all suffering in replacing this bit of kit. Simultaneously it would prevent us from gaining an intimate knowledge of our boats systems / weak points.
