[Public-List] Garboard drains

Mon Apr 22 06:04:22 PDT 2019

Hello Mike - 

Nearly 100% of yachts built in the USA and Canada up to the present have lead ballast…  Iron went out of favour before the big switch to fibreglass and fin keels except in a very few cases; the Alberg 30 and Shark classes being two (and perhaps only…)   Iron as ballast has nothing going for it but cost savings.

Carl Alberg designed our boats to have lead ballast… but Kurt Hansen of Whitby Boatworks switched to iron reckoning in a one design class the loss of performance would not matter if all in the class suffered it equally.  Similarly, we were supposed to have bendy fractional rigs like the Folkboats… but Hansen reckoned the oversized ’totem pole’ masts we have would be cheaper to build… and I reckon he made correct decisions on both counts.   The Whitby Boatworks had a long and profitable run.
