Reverse-inclined bow moulds were first seen on multihulls. But now the concept also seems to make sense for monohulls

Wave piercing is the magic word for a new design philosophy: the floating body is no longer moved over the waves, but through them. Until now, this only seemed to be possible with catamarans and trimarans. However, more and more monohulls with backward-facing bows are appearing. The most recent examples are the new single class Volvo 65 the Italian daysailer Vismara 34 DS and, just launched, the prototype Speeddream 27. It is a test vehicle for a large monohull with which the American adventurer Brian Hancock wants to break all previous records.

Parallels can quickly be drawn. The more straight sterns became established in racing boats, the more they also appeared in cruising boats - and are the rule today. What if negatively inclined sterns now prevail in regattas? Will they soon be the norm on club pontoons too? Should waves also be pierced with cruising yachts in future?

The answers can be found in the current issue of YACHT 23/2012.
