Every time they shed they grow about 25% on size, but the time on the intermolt (hard) stage depends on the size of the crab, lets say that a 10cm crab will take about a month to shed again and become a 13cm crab. more less.

In general a crab life cycle from egg to dead is considered 3 years.  Of course some live longer.  The eggs hatch out in the summer; they spend a few months off of the coast as part of the plankton mass; drift back into the bay in Aug. to Sept. (they can only swim up and down so wind and currents and wind has a lot do do with it, north east blows are a good thing); they may be mature and lay eggs at the end of the second summer but vast majority have done so by the end of the thrid summer.
