Here's a photo of Wind Star sailing from Tongatapu, Tonga on a 50 Nm hop to Kelefesia in the Ha'apai Group in 2008. After departing at 04:00 and feeling our way out through the shipping channel (some lights were missing) here we're in nice flat water doing about 6 Kts, 3 reefs in the main, genoa partially furled. We could have managed well with 2 reefs but we like to be a bit conservative.
