Hi RPD,
The market in Ireland is v small and finding a rib in good condition can be difficult, so take your time.
Two things to be aware of, not the only two things mind you.
Firstly, any boat bought from mainland UK is subject to significant taxation on its way into ROI,
www.afloat.ie have some guidance. Boats from NI may or may not be subject to taxation, best to Google it.
Secondly, transport costs from mainland Europe can be surprisingly high.
Happy searching and remember “buyer beware” (i.e. a survey might save you a world of hurt)
