During the winter of 2003 I had the steering pedestal of my Swan 43 dis-assembled and internal components overhauled at Jamestown Boat Yard in Jamestown, Rhode Island in the U.S.
My Swan has the original rudder and trim-tab and the steering pedestal is original to the boat. Like many of you who have the active trim-tabs know the original cross-section drawing from Nautor (with notes in Finnish) is very diagrammatic and difficult to comprehend.
I had made numerous false starts over the years in my attempts to perform the overhaul work myself but become intimidated at the possibility that the steering shaft and it’s components could not be re-assembled to specs.
Based on the work performed by Jamestown Boat Yard I can say that the shaft assembly is actually quite simple and the work can be performed by the boat owner with average mechanical skills.I have attached photos from the overhaul work for information.
The shaft and associated gears appear to be reasonably robust and should not require any replacement, just a thorough cleaning.The only portion of the assembly that required replacement was the aft nylon bushing which supports the aft end of the shaft.This bushing on my boat developed uneven wear and had become slightly out-of-round creating rotational friction to the steering (see figure 4).
One tip when doing this work is to make sure to maintain tension to the steering cables and chain so they do not fall out of the sheaves inside the boat.You will see that the trim-tab cables have an especially circuitous routing inside the boat and bilge areas and I did not want to have to re-feed the cables through these sheeves (see figure 8). more

This book was started and maintained by the input of dedicated owners of vintage PJ/Swan 43s. It is intended as a dynamic workbook maintained periodically with input from those owners interested in comparing notes and exchanging information on the care, maintenance and operation of these exceptional vintage Sparkman & Stephens designed and Nautor built boats.

S ailboat rigging on a sailboat is the collection of apparatuses through which the force of the wind is transferred to the ship, in order to propel it forward. The term rigging consists of a group of mechanical sailing apparatus, that are attached to the sailboat's hull in order to move the boat as a whole. This could include ropes and/or cables attaching the spars and sails. This will allow to manipulate their position and sail shape. The sails are mostly aerofoil usually made of light weight fabric used to catch the wind. Among the rigging components are spars, masts and other solid objects to whom the sails are attached. more

The term standing rigging on a sailboat refers to a series of lines, wires, and rods which are fixed in position to make the sailboat move while under sail. It specifically stands for the rigging parts that are placed under tension to keep the various spars, mast, and bowsprit, securely in position to make the sail handle wind loads.

[Olamaica1989]

Mainsail Area = P x E / 2
Headsail Area = (Luff x LP) / 2 (LP = shortest distance between clew and Luff)
Genoa Area 150% = ( 1.5 x J x I ) / 2
Genoa Area 135% = ( 1.35 x J x I ) / 2
Fore-triangle 100% = ( I x J ) / 2
Spinnaker Area = 1.8 x J x I more

The rigging mast of a sailboat is a tall vertical pole which supports the sails. Bigger ships could have several masts. This will vary depending on the size and configuration of the ship. The sailboat's masts are named from bow to stern or front to back.

The Swan 47 has also been marketed as NYYC 48 and she is as well listed, on Boat-Specs.com, in Keel and centerboard version (see all the versions compared).

The ratio sail area to displacement can be used to compare the relative sail plan of different sailboats no matter what their size.

[lishan1997]

a DLR less than 180 is indicative of a really light sailboat (race boat made for planning), while a DLR greater than 300 is indicative of a heavy cruising sailboat.
