KISMET MULTIHULL DEZINES

ABOUT THE DESIGNER

Swedish born BILL KRISTOFFERSON studied Naval Architecture and Structural Engineering in Stockholm Sweden. He worked in various parts of the world during a round the world voyage and arrived in Canada in 1964- became a citizen in 1972.
Bill has made numerous ocean crossings in many different types of vessels the Mediterranean in an Arabic dhow, The North Atlantic in a Danish double ender, the Pacific Ocean in a Trimaran. His experience is based on 50% multihull and 50% monohull sailing. Although he likes to sail on all types of sailing craft his preference is to sail on a well designed multihull.
As a qualified shipwright and a naval architect, he has worked in several shipyards over the years in a managerial and supervisory capacity. The building of many vessels of all types; fish boats, pleasure boats, and commercial tugboats, has provided an intimate knowledge of material and design concepts.
He is in the unique position as a designer to be able to draw on the experience of 8 1/2 years of living onboard a multihull with his family. The first Kismet design was drawn in 1968. Bill has also personally built his own boats including the well known "Star of Kismet ".
For the last 30 years research has been continous. The years 1987-88 were spent sailing and working in Australia and provided a great opportunity to see what was happening down under. In 1989 he was residing in Spain, sailing the Mediterranean and checking out the great European racing multihulls. All information has been gathered, collected and assessed. The result of all this is to be seen in the Kismet designs.

SOME HISTORICAL FACTS

There are some sailors who think the multihull is a new type of sailing vessel.
The fact is that the external keel ballasted monohull, being just over 100 years old is the new kid on the block, while the catamaran and double outrigger (trimaran) are several centuries old.
Log books of the explorers of old i.e. Captain Cook comment on the incredible speed of the outrigger canoes and catamarans which sped around their ungainly square rigged craft. Long before Europeans were making ocean crossings under sail, the Polynesian people migrated to all points in the South Pacific using multihulls
Today, the outrigger canoes and catamarans are still functioning as working craft through many parts of the south pacific. It is interesting to note that these multihulls were being constructed before the advent of iron tools, using stone tools and hot rocks for steam forming the hulls. Sadly the art of building the big sailing double canoes have long since passed in Polynesia, only the single and double outrigger survive as fishing, working craft and coastal cruisers.
Today we are seeing a world wide comeback of these unique craft. Ocean going catamarans and trimarans are especially popular in the charter trade. The reason for this resurgence of popularity is the incorporation of modern design features and modern technology in the area of materials and engineering techniques. Marrying the old with the new and incorporating the best of each has resulted in the evolution of outstanding ocean cruising and racing craft. The proof of this is the fact that nearly all ocean crossing records in the world are held by multihulls.

MULTIHULLS TODAY

Basically multihull designs have split into 3 groups.

1 - The racing oriented designs consist of very slender hulls which are extremely weight conscious with very spartan, miniscule accommodation and over size sail plans. They require very experienced skippers who sacrifice comfort for great speed.

Two types of cruising multihulls

2 -The performance cruiser provides exceptional performance with comfortable but not luxurious accommodations and a rig which will ensure a high average speed made good. It also requires a Skipper who will make every attempt to keep his vessel as light as possible and on her designed waterline.

3 - The sumptuous luxury cruiser small or large has every appliance and gadget to make life easier. A skipper who enjoys this great comfort at the expense of speed and performance. At the moment this type is probably the most popular.
There is a place for all 3 types in our life. Unfortunately many turn their type 1 and 2 into type 3 by overburdening them , this is not advisable.
It would be much better to decide which craft is for you and buy or build one designed to suit your type of sailing.
However keep in mind that at times speed is one of the greatest safety factors for many reasons e.g.

- Shortage of water ( tanks dry, water maker on the fritz)

- Shortage of food ( slow voyage, fridge and or freezer on the blink)

- Medical emergency.

A faster boat will insure that you make your landfall sooner.

Designers have learned a lot during the last 25 years. While nothing revolutionary has surfaced,(contrary to what some would have you believe) a better understanding of the existing data bank has made predicting performance and designing to achieve it, much more feasible.
This has led to improvements in sails, rigging and a better understanding of materials, and a greater ability to design to the intended type of utilization.
Designs have become more aerodynamic and this further enhances performance as well as making them more aesthetically pleasing.

DESIGN PHILOSOPHY

For the last 3 decades Kismet Yachts have concentrated on providing safe, comfortable, and simple to construct high performance live aboard ocean cruisers. We are happy to see them in harbours all over the globe, after safe, successful crossings of the worlds oceans.
It is not necessary to come out with a new design every year or two as some obviously feel is essential. Our designs of 25 years ago are still capable of making the same successful ocean crossings today as yesteryear.
Some aspects of aesthetics have been overdone in our opinion, for the sake of a racy look. Too many sloping surfaces undulating across the decks have been incorporated. This makes for unsure and slippery footing.
Also when sitting in the cockpit we should be able to see all four corners of the boat.
While in Australia I assisted on a delivery trip up the Queensland coast on a large bridge deck catamaran. It was necessary while helming the boat to either sit in a very high swivel seat or stand on a cockpit seat leaning over at a very precarious angle in order to see over the bridge deck. Neither position was very comfortable and gave me an awfully sore back. It is like having the windshield of your car blacked out and having to stick your head out the sunroof to see where you are going.
The boats must be easily driven, have uncluttered level decks with few encumbrances. Furthermore you should be able to see over the cabin top while working from the cockpit sole (floor), have easy access to all controls, (sheets, halliards, lines etc.) in order to be able to single hand your boat safely if and when necessary.
At Kismet Yachts each vessel is created to fulfill the design parameters laid down for the individual yacht. On a cruiser, a high average speed under a full cruising payload, is more important than blazing speed, which can only be found while sailing ultra-light in high winds on smooth water.
We believe that good performance is the most significant safety factor available to the sailor. A fast passage maker means that you are always closer to medical attention, fresh water and food.
A fast vessel must move through the water with a minimum of resistance ( to slip the punches of the ocean rather than stand head to head and slug it out). This efficiency makes for a comfortable ride.
Having lived aboard as a family for over 8 1/2 years, we are appreciative of the fact that to live aboard full time, rather than just for the duration of a cruise, means a higher payload . Kismets are designed to sail efficiently with a reasonable payload.
There is a price to pay for performance. We have to balance weight and windage against accommodation, and be satisfied with comfortable, not lavish accommodation.
You will never find a room-maran (a multihull that sleeps many more bodies than it can support i.e. feed) that keeps up with the faster part of the fleet. In fact upon close examination of the room-maran fleet you will find that at least 1/3 of them can't even keep up with the monohulls. Room-marans are only fast when in harbour telling tales.
A multihull, must be capable of exhilarating us with the occasional burst of sheer speed.
For years we have avoided designing any multihulls smaller than 31 ft as it was felt that they were two small to carry the required payload for extended coastal cruises. After designing, building and sailing the K24 T ( 24 foot trimaran ) and the K24 C (24 foot catamaran) we found them incredibly comfortable for extended coastal cruises.
They are much more economical ( upkeep, moorage etc.) Easier to handle and offer more chance of finding space at marinas etc.
We have now developed several smaller coastal cruisers. Our goal was to provide a more affordable, lighter, and easier handling craft for those whose cruising goals do include exciting and fulfilling coastal cruising and explorations of our national waterways and archipelagos, but do exclude ocean crossings or living on board full time.
These cruisers include accommodation for comfortable cruises.
We often meet Kismet sailors just in from a sail who are exhilarated and excited after having a fantastic sail. It is up to you to choose a boat that provides this kind of excitement.

THE CHOICE IS YOURS

Why choose a Multihull over a Monohull

Both Multihulls and Monohulls have evolved into vessels that have been proven safe on any ocean. Therefore, we do not believe that you should choose one overthe other because of some preconceived idea that one is safer than the other. Of course nothing in this world is absolutely safe. Cruising in your boat, whatever the configuration, is not 100% safe, any more than driving your automobile to the wharf is safe. In fact driving an automobile is probably the single most dangerous activity we engage in, in our society. But familiarity breeds contempt and we don't even acknowledge the danger anymore.
It is very important to assess the type of sailing you intend to do (duration, equipment, stores etc.) in order to be able to make a choice of what size vessel is required. Most experienced cruisers will recommend that you choose the smallest vessel which will serve your needs.
The performance and seaworthiness of an overloaded sailboat, whether monohull or multihull, deteriorates greatly, particularly in the case of a multihull which is inherently more weight conscious.
While it is not true that multihulls are always in all circumstances;

- Roomier than any monohull

- Safer than any monohull

- Faster than any monohull

It is true that, in the majority of cases a well designed multihull will be superior to a monohull in the above situations. However a well found larger racing monohull could come along and force us to stare at her transom. In general the performance Multihull cruiser is approximately 30% faster than a comparable monohull in the cruising mode.

Let's choose a multihull simply for the reason that they are exciting practical sailing yachts incorporating superior comfort, speed and safety.

In one of his last interviews before his death, Herreshoff said that if he had his life to live over again he would have spent much more time working with multihulls. What better recommendation could we ask for.

Stability

A Multihull sails with a minimal amount of heel. This makes handling of sails, cooking and domestic duties easier. Even sitting on the head becomes a small pleasure rather than an acrobatic feat.

Shallow draft and beachability

This is a distinct advantage. Cruising the shallow estuaries increases your cruising area.
-Beach the boat for painting and repairs. This will save the owner hundreds of dollars.
-If beached on unfriendly shores the multihull with it's shallow draft will deposit you high and dry on the beach while the monohull with it's deep draft will founder in the heaviest breaking surf making abandoning ship very treacherous.

Motion

In general, motion on a multihull is far kinder than a monohull.
-Windward - Finer hulls and no ballast thus less pounding and less pitching if designed with a fuller stern.
-Downwind - Not as much rolling because of greater beam, no great danger of broaching.
-Reaching - Beam makes for stable exciting sailing. This is what multis are made for!

Capsize

Every body mentions capsize when multihulls are the topic of conversation. Contrary to public opinion, multihull capsizes are not common in cruising multis. Most capsizes have been in the racing category and taken place because the boat has been sailed over when racing- not because of a roll over by enormous seas. The small percentage which have capsized by wave action, in some cases with no sail set, have left the unsinkable multihull floating upside down.
Now compare this with a monohull. Much has been made of the fact that a monohull is self righting and thus will survive a roll over if her hatches are battened down. If not, she will fill with water and sink. Bear in mind that most modern monohulls have approximately 50% ballast, which means they are half sunk before they leave the dock.
More dangerous than capsize for a monohull is the danger of being holed. A recent yachting magazine had an article on monohulls that had been holed. In most cases, when the boat could not be saved, they sank in less than 5 minutes, not giving the survivors time to gather up emergency rations and necessary documents or get themselves organized. Multihulls on the other hand have sailed hundreds of miles with one or more hulls holed or even trimarans with one hull lost completely.

So lets look at the problem logically.

In the most unlikely and extreme scenario, it becomes a choice as to what you prefer, floating around in a small rubber raft with some emergency rations, or floating around in an overturned multihull with all your supplies and water on a larger more visible raft which would be more likely to be spotted.
In many cases the multihulls that have capsized for whatever reason have been towed to shore, righted and renovated. They are out there sailing again. On the other hand it is almost unheard of to raise a sunken monohull. Even if you know the exact spot where it lies, the depth of water makes the recovery too costly.

Building Methods & Materials

We design almost exclusively for the homebuilder and our goal is to provide good designs which utilize so called low tech materials ( wood, plywood and epoxy) while providing high tech performance. Every effort is made to ensure that the designs are pleasing to look at, something to be proud of.
We have adapted our designs to a new building system which will speed up the assembly time to an incredible degree. The hull sides and all connecting bulkheads are built flat on a table full length, then wrapped around a minimal number of bulkheads and the hull bottoms are joined to the hull sides. This means that components can be built separately if desired, which in some circumstances could be very expedient depending on the building site.
Kismet multihulls can be fabricated using most of the modern building materials and methods currently employed in the building of a modern multihull.

THE CHOICE IS YOURS

"To me the pleasure of sailing is almost in direct proportion to the speed."

KISMET DESIGN FEATURES
Hulls

Kismet designs are available in round bilge, multiple chine and flat bottom dory style hulls for the smaller designs. The dory shaped flat bottomed hulls are surprisingly effective in the smaller designs as there is so little boat in the water.

- Have clean hulls with good load carrying capacity,

-Lowest wetted surface,

-A developed hull shape which will reduce pitching,

-Angled or flared hull sides, to provide roomier interiors, and expanded load capacity.

Wing decks (trimarans)

Wingdecks are cut back further than most designs for two reasons,
- to keep the bows of the vessel lighter
- to keep the underwings from pounding at sea

Bridgedecks (catamarans)

Bridgedecks are kept as low as possible with lots of underwing clearance to the water. It is absolutely vital that a person seated in the cockpit have unobstructed vision over the cabin top. This also decreases windage.

Bridge decks are also held back as much as possible to eliminate the danger of damage to the leading edge and to keep the bows light.

Decks should be clear, without the usual obstacle course. Decks must be designed for people not mountain goats. Our pride in performance should come from the sailing, not from having managed to get on top of the bridge deck without outside assistance.

A single level deck insures that both feet are on deck, rather than one foot on deck and the other on a cabin top or some other sloping surface. Unobstructed work areas make for safety and efficiency.

Every attempt is made to insure that decks ahead of the mast are unobstructed for easier sailhandling.

Accommodation

After living on board personally and receiving feed-back for over two decades from many other sailors living on board, we have established a high standard of accommodation design, which is practical at both dock and at sea. This is of the utmost importance, as we have seen many accommodation plans that are lovely at the dock, but completely untenable at sea and vice versa.

Rig

For most of our designs we use a conventional masthead rig and sails.
However some of our more performance oriented cruisers have been designed to incorporate fully battened and semi fully battened sails ( full battens in the upper section of the sails only ), 3/4 rig rotating and fixed masts.
The advantages of this rig configuration are, less windage and less compression load from mast.

Cost

Multihulls are slightly cheaper to build than a monohull, as they are lighter. The cost of any boat is closely related to the weight of materials. Also an important factor is the type of finish and the amount of equipment used.
Keep in mind that the labour to build a boat of a superior design is the same as building a mediocre design, provided they are the same size. The cash outlay will be very similar.
You too can build a Kismet Multihull if you have the determination and initiative to dedicate your time to the project. Experience has shown us that the above attributes are more important than actual boat building experience.
98% of our builders were completely inexperienced at the start of their projects. We also found no correlation between previous sailing experience and successful ocean crossings after completion of their projects. Most successful builders went on to learn to sail, cruise locally, accumulate experience, then go on to more extensive cruising.
In other words the successful sailors do things one step at a time. SO CAN YOU!

Remember, the first step is the most difficult, the others come easier.

There are two types of people in this world, the DOERS and the CRITICS.

THOSE WHO CAN, DO!

THOSE WHO CAN NOT, CRITICIZE!

THE BEST OF LUCK IN WHAT EVER STEPS YOU DECIDE TO TAKE.
