Generally, for a small outboard-powered cruiser, the advice seems to be to approach the mooring very slowly, bow at 20 -30 degrees to the bank / pontoon, when bow is just off the mooring point put helm hard over away from mooring and use a little astern power to pull the stern into the bank / pontoon. Then step off with a line attached to a centre cleat in hand and secure the boat. Then attach the bow and sten lines and stow the centre line. Seems to work fine for me and my 23' cruiser.
