The B1 Cherub (Bieker’s first Cherub) was designed for David Chisholm of Integra Composites in the UK. The company name for the skiff is the GT60. The goal was to a produce a design which would fit within the UK Cherub class rule but have the potential to have appeal outside that class. I used what I have learned from my exposure to the 12 foot skiffs and the R Class skiffs, as well as my knowledge from the 14’s to design this boat. The narrow, low drag shape of this hull make it a natural performer, especially upwind. A crew sailing this skiff won the UK Cherub Nationals with 12 straight wins.
