An advantage the Pococks used to enjoy was one could just move the riggers anywhere on the boat without changing spread. I don't think they enjoy this advantage over the newer Vespuchi wings.
My biggest objection is something Sean touched on and that is the logistics of having so many different boat makes in the BH. Almost impossible to keep an adequate supply of spare parts. Other considerations are ease of maintenance, especially replacing fins. Resolutes require a special clay to seal the fin box from water. Replacing rudders is even more complicated as they require one to cut and fit the rudder to the boat.
I like the simple bolt on fin of the Vespoli, anyone can do it without tools or sealant.
Contrary to what some might think I did not buy the Pococks. Only one boat bought since I came on board and that is the black Vespoli 4X which was a demo we got for less than full price.
The Swifts were bought a year or so before me, used from a club up north. Which is why Swift won't correct the rigger issue. Not sure where or how we got the Filippi 4X or 2X. They're old but still very stiff and under weight. The 4X is about a kg under weight so I put a steel weight in there a while ago. I haven't looked for it for some time but it might still be there.
