I was walking thru the yard a few days ago and saw an 84 Lazzara which caught my eye because of the enclosed shafts and skegs protecting the props. Seems like a great idea, more efficient, better protection etc... And a ridiculously skinny draft. Low tech too... But if it's really as great as it seems... Why is it such a rare set up? I read the original review here and it seemed pretty positive... But I setill have to wonder why other builders haven't gone this way Anyone with real world experience running and maintaining these. Did Lazzara use it on other boats besides the 2005-2010 or so 84?
