For comparison, António also sent photos of a Portuguese type known as the arte xavega, also launched through surf:
Visible similarities include great amounts of sheer and rocker, substantial overhangs, high ends, and general suitability for the dangers of launching and landing through surf, although the xavega appears to have finer lines and to be more extreme in general. The final photo of the Portuguese boats seems to show a sailing rig being loaded aboard, while oddly-shaped oars appear to be the only form of propulsion for the Indian vessel. Of course, one would not expect to see Indian craft being launched by cattle as they are in Portugal. India's substantial manpower resources make up the difference.
Thanks again to António for this interesting comparison.
