DID NOT MAINTAIN ASSIGNED HEADING.

Narrative

PF HAD MINIMAL EXPERIENCE IN THIS ACFT TYPE (LESS THAN 50 HRS) AND HAD NOT FLOWN ACFT IN 6 MONTHS. AFTER DEP FROM SEA LEVEL ARPT; DEP CTL RESTR US TO 2000' (WE HAD ORIGINALLY BEEN CLRED TO MAINTAIN 10000'). LEVEL AT 2000' WE WERE IN AND OUT OF THE CLOUDS. I WAS WATCHING FOR TFC; OPP DIRECTION AT 3000' AND ALSO MONITORING OUR AIRSPD AND ALT AS PF WAS HAVING DIFFICULTY CTLING ACFT. I FAILED TO NOTICE THAT PF HAD ALLOWED OUR HDG TO DRIFT 20 DEGS TO THE RIGHT OF THE HDG ASSIGNED IN THE SID. I POINTED THIS OUT TO THE PF ALONG WITH SUGGESTIONS ON HOW TO STABILIZE ACFT ALT AND SPD. WE RETURNED TO NORMAL DEP PROFILE. CONTRIBUTING FACTORS: 1) BASED ON ORIGINAL CLRNC; BOTH PLTS WERE PROGRAMMED FOR A CLB TO 10000'. IF WE HAD BEEN AWARE OF THE 2000' RESTRICTION PRIOR TO TKOF; I WOULD HAVE SUGGESTED A LOWER CLB THRUST SETTING AFTER FLAP RETRACTION TO FACILITATE SPD AND ALT CONTROL. 2) PF DID NOT HAVE RECENT EXPERIENCE IN THE ACFT (ALTHOUGH HE WAS LEGAL AS SIC). IT MAY BE ASKING TOO MUCH OF SOMEONE WHO HASN'T FLOWN IN A SPECIFIC TYPE OT MAKE THEIR FIRST DEP INTO IMC CONDITIONS AND THEN THROW A LOW ALT RESTRICTION AT THEM.
