There is a German Cat that has an arch P/S (two masts) that would be great for getting under bridges. If I were ever to lose my present rig I would consider an arch as a replacement. Which would eliminate shrouds P/S.
Arch rigs can also be used on powerboats for before the wind
, someting I considered back in the 80's.
This Lila-Lou seems a bit top heavy and would require more keel
weight, whick may not matter on a large vessel of >100'.
