Narrative:

We departed runway 19 out of teb. We were given the dalton SID. The owner of the airplane who is a pilot asked to fly the leg home. I; the captain who have flown with him before; agreed. After takeoff the clearance is to climb to 800 ft then a right turn to a heading of 280 and continue climb to 1300 ft. After 800 ft he made the right turn to 280 and continued climbing to 1300 ft I noticed that he pulled the power back and started to level off. I called out 100 ft to go and felt that he was not leveling off quick enough so I said it again but at that time it was too late; he had climbed past 1300 ft and was still climbing. I took command of the airplane and leveled off; but by the time I recovered; we busted altitude. Tower called during the climb and told us to level off at the mandatory altitude of 1300 ft and told us to respond. I did and there were no more conversations regarding the incident. In the future I plan on flying the airplane myself where there are such tight restrictions on heading and altitude. I don't mind letting the owner fly but it is my license on the line.
