Joe Tracy's boat at the launching site
Description (in Rick Willoughby's words):
«The boat started as a V15 design but incorporates the learning from V15 users and the latest V16 hull shape. The V16 series has variable side flare so has slightly less drag than the V15 series. It also has a tiny transom.
Joe's boat has a design displacement of 130kg; that being Joe plus gear and design boat weight of 20kg. The finished boat weight is 24kg. A good result for a 6.4m long boat capable of carrying 100+kg. The main hull is probably the best built to my design to date and weighed just 11kg prior to painting. The stabilisers use solid EPS foam with epoxy/glass cover.»
From a practical angle, Joe writes us: «I am able to launch and retrieve the boat by myself by backing up to the water. I leave it set up on my truck carrier so no time is wasted when I launch.» See for yourself:

Right now I am at 1:6 ratio, which is the highest ratio using the 1:3 belt drive and 1:2 gear box. With a chain drive I can move toward Rick's recommendation of 1:7 or any other ratio I may wish to try.»
