Rick's Ultimate Design...

Some of you may have heard of the HPB group (Human Powered Boats).  These are a group of very intelligent, both skilled amateur and professional, designers, builders and testers of cutting edge ideas.  The big Kahuna over at Hobie was once a very active member of HPB, back when he just couldn't seem to make his flippers flap very well.  Their typical goal is high performance in mostly one man, human powered boats.  There are multihulls and single hulls.  There are varying propelling devices, but...

They are all human powered, and some are very, very fast.

Rick Willoughby is one of the best:



This sleek craft is about 19 or 20 feet long and one of, if not THE fastest design on the water.  Allow me to point out some of it's great features.

1.  It is very, very light.

2.  It is very, very strong.

3.  The prop drive is very, very efficient - probably around 85% or better (compare to the Kahuna's delicate flippers at maybe 20%).  Not much wasted energy.

4.  The drive easily retracts with a single hand, for shallow water, for paddling or for cleaning.  It has minimal, bulletproof moving parts.  It will not break, nor needs much maintenance.

5.  The outriggers easily fold up, either or both, as needed or not.  

6.  The double rudder is small, efficient, and very, very effective.  Even with its minor drag, it drops only when needed and adds very, very little pendulum weight.

7.  The paddler sits high and dry, and comfortably reclined.  The  circular pedaling drive has long been considered the most efficient, least wearing arrangement for maximum performance.  The reclining position is both comfortable and very, very powerful.

I hope you understand that nothing on Rick's designs happens without careful analysis and much, much testing... leaving very, very little to chance.

Congrats, Rick!
