Catalog of Radio-Controlled Square-Riggers (Windjammers)

Catalogue de voiliers radio-commandés à gréement carré

Katalog von RC-Rahseglern

Introduction

Square-Riggers comprise brigantines, brigs, barquentines, three- or four-masted barques (also called barks), and full-rigged ships. For the sake of controlling systems I only marginally include topsail schooners. If you are interested in fore and aft schooners (I understand!) check http://www.pittelli.com/schooner/links.html.

Propeller-driven radio-control boats may be fun to build but quickly become very boring to operate, unless you are heavily into boat races and you like to tweak the most power out of electric or gas-powered motors. Radio-control sailboats are more fun, but there again, most are plain sloops optimized for weekend racing on the local pond. I actually put together and sailed a two-channel Victoria sloop, which is a good pretext to sit by the water in a gentle breeze. Owing to the complexity of both construction and operation, there are not many sailing models of squareriggers, but that is what makes them challenging, and actually closer to robots than toys.

I would like to build a typical three-masted barque. It would have four channels, one for mizzen, one for main, one for spanker (air rudder), and one for rudder. In my copious free time, I have not started yet, so I can only gawk at what others are doing. Please send me updates, details, or new links for the Catalogue.

Details of yard and sail controlling systems

There are many control lines going through the deck (http://www.minisail-classic.de/).
Radio-control panel of the Cutty Sark, unbelievable (http://www.minisail-classic.de/).
Inside the Cutty Sark radio-control box are actually two transmitters! (http://www.minisail-classic.de/)

Brooks Martin (USA) http://www.rcgroups.com/forums/showthread.php?t=761962 also contains information on the nested jibs
Bracing servos of the Pamir

Steel, Chapman & Hutchinson Ltd (USA) Here is a series of pictures and captions courtesy of Philip Roberts for HMS Surprise. They starts at the mainyard and go down to end at the servo arm. The main and mizzen lower yards are controlled by the same servo.

The amidships area of the mainyard showing the yard support - the bent brass "hook" and the eye in the aft face of the yard that goes over this, held in place to rotate freely by the 2 collars.

The lead of the brace back from the eye in the yard through the brace guide. This is a delrin bar fastened on the aft side of the mast with a sheave in either end. Nowadays the ends of this brace guide are positioned further aft by means of dog legs in the bar to ensure 45° yard movement each side under all conditions.

The braces come out the aft end of the brace guide (ends hidden in the shrouds (no futtock shrouds on this model)) and converge through an eye on the aft side of the mast.

The braces reach the deck and go through polypro tubes which act as fairleads (to blocks on either side of the mast below deck) and water seals. Please ignore the wavy hatch grating! The prototype ships get no cosmetic attention!

Looking through the mechanical hatch here into the space beneath the deck: the top of a 2:1 geared servo showing the starboard half of the servo arm (delrin) the many-holed adjuster plates screwed to the top of the arm (the inside one is the mizen brace, the outside one the main brace) with the braces tied to them leading aft to a block attached to the masts below decks which allow the braces to turn 90° and penetrate the deck through the polypro tubes.

Independent control of yards and sheets of mizzen and main masts.
Detail of the two servos under the deck.
John Tom (Thailand) http://www.john-tom.com/RcShip/RCship.html, Brigantine Edith Ann. The Foremast is mounted on two precision sealed bearings, one at the bottom of the hull and the other mounted to the underside of the deck to allow the Foremast to rotate freely. The Mainmast (which is fore and aft rigged) is controlled by a high-torque servo modified to work as a winch by replacing the servo potentiometer with three 2.8 kOhm resistors (or disconnecting the potentiometer on JR servos).
Push rods connect the Foremast directly to a high-torque Servo (9kg/cm) and the servo speed and travel is reduced from the transmitter (JR PCM9 x2).

Computer Simulation

Peter Davis (NL) has written a great simulation of a 3-masted ship (HMS Surprise), or also of a 19th century brig, running on Microsoft Windows. Go to http://home.wxs.nl/~pdavis/index.htm, download the 120 KB zip file, unzip it, run Surprise.exe, and here you are having to give bracing and reefing orders, and headings to the helmsman!
