many faces of the Lambay Island/Howth Head 22' Motor Cruiser.
work is rarely static - over the years that a particular boat
design exists, different clients come alog and ask for changes
which may involve alterations to length, beam etc as well as to
keels, rigs etc. Here we have photos (immediately below) by
Dennis Nissen of his 22' Howth Head, which he increased in
length to 30' with a beam of 9', on the 'Building Wooden Boats'
Facebook page, after I put up photos of Andy Frankland's 22'
version with a fisherman style wheelhouse on the Selway Fisher
Design Facebook page - Selway

drawings for the 30 footer do not actually exist as Dennis
simply took the details for the 22' Lambay Island and 'blew'
them up for a 30' x 9' version which turned out very well. When
doing this you have to be careful of things like subsequent
alterations to the displacement volume which, when increasing
the size of a design, can become embarrassingly large making the
hull sit too high - but this has not happened with Dennis's
when decreasing the size of a boat, the displacement volume will
drop quickly leaving you with not enough volume below the
waterline to carry the boat's weight, making the boat sink lower
than you would want.
