The Formosa 42 Sailboat (aka the Slocum 43) Specs & Key Performance Indicators

The Formosa 42 is a classic cruising sailboat that was designed by Stan Huntingford and built in Taiwan by Formosa Boat Building Co Ltd from 1981 to 1990. It is also known as the Slocum 43, after the famous circumnavigator Joshua Slocum. The Formosa 42 is an aft cockpit cutter with a fin keel and a skeg-hung rudder. It has a spacious interior with a traditional layout and plenty of teak woodwork. The Formosa 42 is a moderate-to-heavy displacement cruiser that can handle offshore passages and long-term living aboard.

Summary Analysis of the Design Ratios for the Formosa 42

1. A Sail Area/Displacement Ratio of just 14.1 suggests that the Formosa 42 will need a stiff breeze to get her going. In light conditions, unless you've got plenty of time on your hands, motor-sailing may be the way to go.

2. A Ballast/Displacement Ratio of 32.0 means that a sailboat like the Formosa 42 (which doesn't have a stiffness-enhancing bulb keel), is likely to bene

fit from being reefed early to keep her sailing upright in a moderate breeze.

3. A Displacement/Length Ratio of 273, tells us the Formosa 42 is a moderate-to-heavy displacement cruiser, which means she'll carry all your cruising gear without it having a dramatic effect on her performance. 

4. Ted Brewer's Comfort Ratio of 38.0 suggests that crew comfort of a Formosa 42 in a seaway is similar to what you would associate with the motion of a moderate bluewater cruising boat - a predictable and acceptable motion for most seasoned sailors.

5. The Capsize Screening Formula (CSF) of 1.7 indicates that a Formosa 42 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0. 

Any Questions?

Is the Formosa 42 still in production and, if not, when did production end and how many of these sailboats were built?

No, the Formosa 42 is not in production anymore. Production ended in 1990, after about 60 boats were built.

What is the history of the builders of the Formosa 42?

Formosa Boat Building Co. Ltd. was founded in 1965 in Kaohsiung, Taiwan, by Y.C. Yang. The company specialized in building fiberglass sailboats based on designs by American naval architects such as William Garden, Doug Peterson, Robert Perry and Stan Huntingford. Some of their most popular models were the Formosa 41, Formosa 46, Formosa 51 and Formosa 68. The company also built boats under other names such as CT, Sea Tiger, Transworld and Island Trader. The company ceased operations in the early 1990s due to financial difficulties and competition from other Asian builders.

What keel options are available for the Formosa 42?

The Formosa 42 has a fin keel with a lead ballast of about 9,000 pounds. The draft is 6 feet 4 inches. Some boats may have a shoal draft version with a draft of 5 feet.

What is the Formosa 42 like to sail?

The Formosa 42 is a stable and comfortable sailboat that can handle various sea conditions. It is not very fast or agile, but it has good directional stability and balance. It performs well on a reach or a run, but it may struggle to point high or tack quickly in light winds. It has a moderate heel angle and a gentle motion at sea. It is easy to handle by a small crew or even single-handed, thanks to its cutter rig and self-tailing winches.

What is the average cost of a secondhand Formosa 42?

The average cost of a secondhand Formosa 42 depends on the condition, equipment and location of the boat. According to YachtWorld.com , as of July 2023, there are six Formosa 42s for sale worldwide, ranging from $50,000 to $150,000 USD. The price may vary depending on the age, maintenance, upgrades and modifications of the boat.

What other sailboats have been created by the designer of the Formosa 42?

The Formosa 42 was designed by Stan Huntingford, a Canadian naval architect who also designed other sailboats such as the Baba 35, the Baba 40, the Island Trader 37, the Island Trader 41, the Island Trader 46, the Slocum 43 and the Slocum 51. He was known for creating sturdy and seaworthy cruising boats with traditional lines and spacious interiors.

Sailing characteristics

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

What is Capsize Screening Formula (CSF)?

The capsize screening value for Formosa 37 is 1.68, indicating that this boat could - if evaluated by this formula alone - be accepted to participate in ocean races.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Formosa 37 is about 247 kg/cm, alternatively 1386 lbs/inch. Meaning: if you load 247 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1386 lbs cargo on the boat it will sink 1 inch.

Due to some Termite damage to Sea Symphony …Mainly in the Mizzen mast (removed) and the companionway stairs… (main mast also removed but clear) I have put her up for sale at the knockdown price of 30 000 EUR… in view of the works that need doing…. She has been sprayed twice throughout and is due to be gas bombed …luckily Termites don't like Teak.

*************************************** OWNERS REMARKS Bought with the intention of sailing around the world, our circumstances have changed and the offer of our dream job means we will be land based for the foreseeable future. We first considered keeping her, but she needs an owner with the time to look after her properly and sail her. Accommodation : She comfortably sleeps 6/8 in 3 cabins. All the way aft is the owner’s stateroom with its own private head. Next forward is the large saloon with seating for eight around the marble table. A steering station is in the saloon. Going forward down three steps to a central passage way one finds the galley to starboard and the port cabin to port. The port cabin comprises one double bunk and one single bunk, ample hanging storage and 3 drawers. Next forward is the starboard cabin. Again comprising one double bunk and one single, hanging locker and drawers. Lots of storage under the bunk. Through the starboard cabin is the forepeak. This houses the generator and sails, tools etc. Between the starboard cabin and the port cabin is the forward head. Both heads have showers. Six people can easily and comfortably sleep on board, two on the double bed in the owner’s stateroom aft, two in the two bunks in the port cabin, and two in the two bunks in the starboard cabin. At a push 3 can sleep in the guest cabins. Two more could bed down if the saloon table were converted to a double bed. Inventory :
