Someone posted another Carter boat recently. Since I had not heard of his boats I did a little kill time searching.
Seems he built some fast boats, and was first overall in the Fastnet in '65 and '69. And second to a new aluminum trimaran
in '72 in a trans atlantic? race
Also very influential in the rules during the beginning of IOR.
Noticed a couple of other unusual design features, too. Some boats had a hydraulic drive in the keel
with the prop at the aft edge.
Another had a most unusual hull
shape aft at the waterline and just below.
I'd post a pic but my boat is lying at a bad angle to the WiFi
onshore and it's dropping out to much.
