Bernard Smith's Amazing sailboats, reference site on the pioneering work that led to Paul Larsen's Vestas Sail Rocket 2

Paul Larsen cites Bernard Smith's seminal work the 40 knot sailboat as his inspiration for creating the ultimately record breaking Vesta's Sail Rocket 2.  Paul and the team suffered a multitude of setbacks in their quest to claim the short course outright sailing records but kept doggedly to the task and were finally rewarded with success easily surpassing the old record and raising the bar for future challengers.

The Proas of John Pizzey Part 1, proafile article

From the following article on the excellent proafile:

http://proafile.com/magazine/article/the-proas-of-john-pizzey

A few thoughts on cruising proas after many years absent from sailing them but hopefully about to get back to the misadventure. As can be seen from the literature, there are any number of possible rig, rudder and centreboard combinations that can be made to work, some easily, some needing a fair amount of skill and diligent attention. The trick is to get a combination that works well. If you can’t easily single-hand the boat I would question its usefulness Furthermore, there is obviously not only one correct solution, or for that matter any solution.
In three of my proas and in several guises I have sailed competitively in mixed fleets, such as the around the buoys Winter Series in Moreton Bay with several hundred monohulls and a few multihulls without causing chaos and in close company with many, mostly on Pi which we sailed frequently in bay and ocean races for more than a decade.

Excellent article on Multihulls World on singlehanded multihull sailing

From the following Multihulls World article

http://www.multihulls-world.com/us/catamarans/dossiers/tips-for-singlehanded-sailors,11.html

Sailing singlehanded on a multihull imposes a different rhythm, greater anticipation and absolute respect of safety rules. Don't think that this subject only concerns real singlehanders. Family cruising with young children finally imposes the same constraints.

Tacking Outrigger reference site

Peter over at tacking outrigger has put up an interesting site detailing his own projects and others from around the world.  Tacking outriggers differ from proas in the sense that they have a fixed rudder and they tack rather than shunt.
