Has anyone any experience with these boats? Sailing capabilitys, speed, problems etc. I'm thinking about purchasing one but can find very little info online about them.
Just for info - I replaced the Yanmar Ysm12 which was underpowered to a 2GM20F. Does the Shamrock have double spreaders? The Rush 30 was single and no reported issues with masts.

Single mast spreaders on Club Shamrock.
quite powerful small hydraulic backstay adjuster (stand alone) lever operated by David Carne Productions,Falmouth.
A lovely miniature piece of kit,repairable by any good hydraulics workshop.
I'd say that new Yanmar is just what a rush needs.
There was much bending of mast used to extract the last ounce of camber from the then Dacron North Sales supplied.
looking down on a plan of the rigging it was obvious after a bit of head scratching that the forces (baby stay, coupled with the forces in the backstay, were enough to move the crosstrees forward perhaps six inches.
The cap shrouds were the forced into an angle change at the crosstrees, which these south to resolve by angling backwards to compensate.The were at inboard ending s/s sockets which also tried to deform and dig into the mast sidewall.
some put rubber bumpers on the inner ends of the crosstrees, others angled cut and shortened the crosstrees, to give some relief and to allow a closer sheeting angle of the genoa.
All in all we gave them murder, spalling Hasselfors bottlescrews frequently and losing rigs under claims agains Hasselfors, which were somewhat successful.
I never lost the rig, but came close when the backstay came down around my ears!Rod riggging crevice corrosion was the culprit.
No more rod rigging about now.
