How big shoud be lead for cruising catamarans??

Do you mean how fast a cruising catamaran is compared to cruising keel-boats?

For cruising cats that are not sailing with one hull lifted free of the water, you need almost zero 'lead'. The requirement for lead was a result of the heel of the monohull and what this did to misalign the centers of force.

It all depends on whether you have daggerboards or "keels". If only the leeward foil is in the water, then it becomes pretty much the same as if you were flying a hull. If there are keels (skegs, whatever...) then it become similar to a monhull.
In fact, it is not only the heel that determines the lead, but the length of the boom and the foot of the headsail which place the CE outboard when upright.
