The Maldives make a good introduction to surf boat charters since the waves are rarely too big or too demanding, unless you sail to the more exposed outer atolls.
For more challenging surfing, there are many other surf boat charter options, including the following:
Bali: escape the usual mainland breaks and experience uncrowded bigger waves. Bali Wave Hunter offers trips from March to November, the main season. baliwavehunter.com 
Fiji: year-round waves can be accessed from the luxurious French-built sailing yacht Stellar, including a number of seldom surfed "secret spots". wavehunters.com 
New Caledonia: a 14-metre Bahia catamaran takes up to eight guests around the South Pacific islands of New Caledonia, where the best waves can be caught from April to September. Huge swells from the north can also occur in winter. theperfectwave.com.au
