Different horses for different courses,ive owned both,currently monos.If i planned on high latitude cruising i would want a moderate to heavy disp Mono, if i thought that the canals of Europe
may figure into my plans the Mono would get the nod,likewise if i wanted a marina queen, but if the Carribean or the South Pacific
were in my plans its a no brainer, i want the huge outdoor living space, less rolling in the tradewinds and at anchor
and of course shallow draft
. There is no perfect boat and most boat types evolved for a specific purpose,multihulls evolved in the Pacific and are still ideal for that type of cruising grounds.These days many people want to carry so much crap with them that perhaps a boat evolved for cargo hauling (mono) is best for them,i dont think one should be predudiced for or against either type,just pick what suits your style of cruising.
