The ad says the design is by Sampson. Maybe it was, because I've not seen anything like it by John Samson
But that doesn't mean much because way down here most ferros are Hartleys - and it might have been a commissioned design anyway.
Be aware though that a lot of home builders chose to alter published designs - invariably to make them bigger - and still attributed them to the designer
. If they'd consulted the designer
and the extensions were approved, all well and good. But ususally the home builder/s thought they knew best...
The deck and cabins being ferro
shouldn't be an issue - it's how most are built and it's structurally sounder to complete the shell that way. Doghouses are timber of course and it's the same with this one. But the weight seems high to me.
My 42 footer tips the scales at 14 tonnes and, just guessing, if a 50+ footer is double the displacement
then the 85,000lbs (nearly 40 tonnes) does seem way too high. For a more direct comparison, there's a 50+ footer ferro
in our club that is 25 tonnes.
So the weight (if I've converted correctly) strongly suggests to me that something is amiss.
Also, the pics don't show much detail on the hull
but the little bit available suggests the finish might be rough. Well finished ferro looks and shines like f/glass.
So while it may be fine for a liveaboard
, I'd tread warily if you intend taking it to sea.
