Boat mooring in Pattaya and Samui

I'd like to find alternatives for mooring the boat in Ocean Marina as it's a bit out of my budget considering my boat's just 23 feet center console. Does anyone has info on other places? I've also planned to go to Koh Samui later this winter and I remember read that Bangrak has places but would there be any in Lamai? And what should one be expecting to pay/month.
