One thing we have noticed in Singapore with the Viper is that it can turtle quite easily and can be really hard to re-right. It is very surprising how quick it happens, and how hard to recover in this situation.

We have speculated about why, but could be the rather large volume hulls in the shorter length. But as I said, speculating. Comparative to a Taipan, the Taipan is dead easy to get back up and going.

Speak to Scott McCook at pro-sail in Singapore more about this. He has the most experience with Vipers with 10 in Singapore.
