This Fantail 49 is only one of nine  imported into the US from the 

renowned Tran world shipyard in Taiwan. This  economical trawler features a
wonderful blend of tradition as well as  practicality. A fuel burn of 25 gals a "Day"
is sure to please the most  frugal yachtsman. Insulation and soundproofing is
excellent. Oversized  15kW generator handles all needs with ease and quiet.
The fantail was  designed to be a beautiful, and efficient cruising yacht, her
hull is very  easily driven. There is 3500 pounds of ballast in the keel which
keeps the  motion gentle and gives a righting moment past 120 angle of heel.
The  standard finish of the Fantail is one of the highest in the industry. The
thought that went into her design is obvious to the discerning  yachtsman.

Dear Patrick and  Tad:

Thank you for all your feedback.

You'll see above the information we get regarding the vessel.

Yesterday i was able to correspond with Steve Davis about the  design and
stability of the fantail.

Here is his email:

Hi Jim,
Happy Holidays to you and your family too.
So many inaccuracies in the information presented.  I did  the conceptual
design and initial styling on this design.  Rob  Ladd drew her lines and did all
the hydrostatics and my good friend,  Bill Scales who worked for Jack Sarin
and later on much larger  designs at Crescent Beach, refined my concept and
really made  her work aesthetically.  These ARE exceptional boats.  There would
have been a lot more of them but the builder got greedy  and refused to pay
royalties to those of us who invested so much but  there were I believe over 12
built and Rob saw one for sale at the  Duessledorf show 10 years ago.  My
friend, Jim Mann who  imported Camper and Nicholson yachts took on the Fantail and
sold  all except the first boat and I believe the one you are looking at.
Most of the boats sold were delivered to the East Coast.
The nature of this design is, essentially, a true trawler hull  form.  We
designed her to be extremely efficient and in fact  she requires only 28 shp to
make hull speed. She has considerable  stability and, in fact the fly bridge
version was more comfortable  as the moment of inertia was increased which
reduced the period of  roll.  Adding a deck box up top or two would help or even a
heavier dink. But remember, this is essentially a sailboat hull with
ballast.  I don't know Patrick Willard but adding more ballast  would be a big
mistake.  I did regret that we didn't add a  chine to her lines back aft which would
have given her initial  stability; the lack of which is typical in sailboats
but not so  typical in the new trawler market dominated by Grand Banks and now
Nordhavn.  These folks were merciless in their criticism of the  very
capable hull form because it was to their advantage to do  so.  My one experience
with a savvy owner was Don  Crowhurst.  I sold him hull no. 1 and he used it to
travel from  California to Alaska for three or four years.  Don had been the
head football coach at Cal Poly for a lot of years and retired with  his wife
to cruise the West Coast with their cats.  He named  the boat Feliner.  He
first owned a Nordhavn that burnt due to  a faulty dry exhaust installation and
his praise of the Fantail  exceeded even what he thought was possible.  I would
put you in  touch with him but he passed away several years ago.  I doubt  if
anyone used their boat more than Don.  We discussed the  reality of stability
and he said it was a matter of  seamanship.  Like a sailboat, you don't want
to take seas beam  on but she is fairly comfortable quartering them.  Don said
he  would watch his weather and go at the best times and he wasn't  afraid of
"tacking" when conditions called for it.  He told me  that he and his wife
were always more rested and comfortable than  their peers in the typical chined
vessels as their motion is very  snappy at sea while certainly more stable
initially.  There is  a price to pay for this initial stability in comfort
offshore.  For someone who understands the hull form, this is not a problem but
for those who don't, they were frightened by stepping aboard and  having the
boat move to their weight,  Never bothered the  sailors but the neophyte power
boat guys and maybe more importantly  their wives, were often overly concerned
because of lack of  knowledge.
I thought she would benefit from active stabilizers and we  designed for them
but they are expensive and are only effective at  over 6 knots plus the
additional wetted surface is more drag so  efficiency goes down.
Paravanes are an option but you have the expense of rigging and  the risk of
damage if the loads are not sufficiently designed  for.  Not for everyone.  I
liked Don's approach.  KISS. Seamanship.
The price is very fair.  She is easily a $400,000  boat.  I'd make certain
her engine and drive train are in  perfect condition but Jim Mann had designed
and installed in several  Fantails he sold, an auxiliary drive system off the
generator via hydraulics.  Since she requires so little hp to  move her, this
was quite effective as well as pretty  inexpensive.

If you have had experience with true displacement hull forms  and have
experience offshore, I believe you will love the  Fantail.  Like all designs she is
a compromise of design.  Were we to do it over, she probably would have a
modified chine aft  to help her initial stability but that would be only for
marketing  purposes.  I think she is everything we hoped she would be from  a
design standpoint.
Feel free to be in touch if you feel the need.
Best,
Steve

Thank you Patrick for your informative  feedback.

We researched that there is 3500 pounds of ballast in  the keel which keeps
the motion gentle and gives a righting moment past  120  angle of heel. I'm
not
sure if this ballast was increased as the  designer  suggested.

We were also told that the Transworld 50'  Fantale  Trawler burns approx. 25
gallons a day with a range of about  1,700 miles.

Your feedback was extremely helpful about the roll.  This  is a concern
especially since the boat had passive stabilizers  added a few years  ago. As
you can
imagine it will be challenging to  experience the roll during the  inspection
and buying process. This  is a concern right now.

The appointments, hull materials, mechanicals  all appear  as you suggest
first class. Especially since the boat  seems to have been  loved.

Again, we really appreciate your  feedback and now have  some serious
considerations to  resolve.

Jim Hughes

Any

feedback on the  fan tale design trawler? IE:  TransWorld.

Better known as the
Fantail  50 trawler.  These boats were built in Taiwan at the Transworld
yard.
They  were beautifully appointed and nicely  finished.  All the  materials
and
equipment aboard were first class.  They have a lot  of  neat details like a
hot
and cold sink in the engine room for  washing up after  servicing the systems
there.  As I recall,  there were only 10 or 11 of  them built.  The biggest
problem  with the full displacement hull is that  it is almost completely
round
in cross section (very little turn at the  chine).  They  got the reputation
for
being very rolly even while at the  dock.  I was on one at a boat show
several
years ago and there  were  about 6 or 7 people aboard and you had to hold onto
something  even while tied  to the dock.  They do not carry enough fuel to be
a
serious open ocean  cruiser.  They are best suited as a coastal  cruiser.  In
my  opinion, they require active fin  stabilizers while under way and  flopper
stoppers while at anchor for  stability.  If you want to pursue  long distance
cruising, you  will have to figure out how to add more fuel  capacity (but
that
would  further complicate the hydro dynamics).  I  talked to the designer  of
the
Fantail 50, the marine illustrator Steve Davis,  and he  felt the boat would
benefit from more ballast.  As you can see,  all of these considerations
starts
to involve a complete redesign of  the  hull.

I really love the design and
finish of this  boat.  I  seriously con_sidered purchasing one about 10 or  12
years ago.  However,  the drawbacks mentioned above made me  look for
alternatives.  I'm happy  I  did.

Jim,

The likelihood that the Fantail 50 will  have positive stability anywhere
near 120 degrees of heel is slim to  impossible. Typical sailing yachts of
these (50' by 15.33') dimensions  would have an angle of vanishing stability
of about 110 degrees.  These are boats with substantial (and deep) outside
ballast keels and no  high deckhouse. In this size boat 3500 pounds of
ballast is a drop in the  bucket, four times that might start to make a
difference in VCG  height.  But still the boat is so shallow that the ballast
can't be  very deep.  The shallow draft, wide beam, and high deckhouse will
add  up to an angle of vanishing stability of approximately 80 degrees.

When  anyone states stability data they must show some documentation,
otherwise  it's just sales talk.  The stability data must show a curve  of
righting arms at a given displacement and VCG height.  Usually  stability
curves are given at several "load conditions". The first load  condition
might be "light ship", this is the complete boat without stores,  crew,
liquids, or owner's items aboard.  The second condition should  be departure
or full load.  This is the complete boat with everything  aboard including
all tanks (except black and grey water) full.  Normally this is the heaviest
(largest displacement) and lowest VCG, thus  the highest stability. The final
load condition is "worst case" or arrival  condition.  In this case the tanks
are at 10 percent, stores are  depleted, but crew and owner's items are
aboard.  This means the boat  is floating high in the water with a high VCG.
Worst case stability is the  final criteria.

The stability of your boat safeguards the lives  of you and your crew, thus
it is worth paying attention to.  The  correct data for your boat can only be
ascertained by the input of proven  information.  The vertical height of G,
the center of gravity for the  entire boat, is subject to much guessing.
This is done because actually  measuring the height of G is an elaborate
undertaking.  It is done by  conducting what's called an "Inclining
Experiment".  This involves  heeling your boat with controlled weights moved
a measured distance and  taking measurements of the angle.  This data along
with the hull lines  and current floatation are the inputs required to arrive
at real stability  that applies to your actual boat. It is not good enough to
state that an  inclining has been done on another similar boat.  These boats
are now  20 years old and many changes (additions) have occurred.  There  may
also be hidden differences in construction that can throw data  off.

The Fantail 50 has always appeared to me to be an unhappy vessel,  to my eye
they appear top heavy with too large and high a deckhouse.  Also someone
miscalculated the weights and they all appear noticeably down  by the stern.
Be aware that fuel consumption will be quite a bit more than  25 gpd at 8
knots, perhaps double that.  To get the 1700 miles you  will need to slow
down to 6 knots or less.

All the best,

Tad  Roberts

researched  that there is 3500 pounds of ballast in  the keel which keeps

the

motion gentle and gives a righting moment past 120  angle  of heel. I'm not

sure if this ballast was increased as the  designer  suggested.

Jim, I
believe that the righting moment  of 120 deg. and 1700 mile range are,
unfortunately, sales hyperbole in my  opinion.  The Fantail 50 is listed at
42,500 lbs disp.  3500 lbs  ballast would be a ballast/displacement ratio of
8%.  My boat has a  ballast/displcement ratio of 21%.  I don't have 120  deg.
stability.  Ballast/displacement ratio is NOT the absolute  indicator of
stability, but only one of many factors to consider.

The ballast was never
increased during the production of the  Fantail 50.  The designer told me he
tought the ballast should have  been increased several years after it went out
of production.

We  were also told that the Transworld 50' Fantale  Trawler

burns approx.  25

gallons a day with a range of about 1,700 miles.

Well
let's run those numbers.  The Fantail 50 lists fuel  capacity at 520 gallons.
If you divide 520 by 25, you have 20.8 days till  all empty.  20.8 days is
499.2 hours.  If you cover 1700 miles in  499.2 hours, then you have an
average
speed of 3.4 knots!

Let's  figure it another way.  If you divide 1700 by 520
fuel capacity you  get 3.3 nautical mpg.  If you burn 25/24 or 1.04 gph,
then multiple  3.3 x 1.04 and again you come up with 3.4 knots!

These numbers
are  theortically possible but 3.4 knots in a trawler is little more  than
drifting with the currents.

My gut feeling is that you will get  about a 1200
to 1400 mile range at 6 to 6.5 knots with no generator or  stabilizers,
burning about 2.5 to 3 gallons per hour, or 70 gal. per  day.  Running
stabiliz_ers and a generator could reduce these  numbers.

Again, we really

appreciate your feedback and now  have  some serious

considerations to

resolve.

Jim, I am  not trying to talk you out of this boat.  I just want you
to have  realistic expectations before plunking your money down.  This may  be
the perfect boat for you, but be informed of its capabilities and
limitations.
Good fortune

In this size boat 3500 pounds of ballast is a drop in the bucket, four times that might start to make a difference in VCG height. But still the boat is so shallow that the ballast can't be very deep. The shallow draft, wide beam, and high deckhouse will add up to an angle of vanishing stability of approximately 80 degrees. When anyone states stability data they must show some documentation, otherwise it's just sales talk. The stability data must show a curve of righting arms at a given displacement and VCG height. Usually stability curves are given at several "load conditions". The first load condition might be "light ship", this is the complete boat without stores, crew, liquids, or owner's items aboard. The second condition should be departure or full load. This is the complete boat with everything aboard including all tanks (except black and grey water) full. Normally this is the heaviest (largest displacement) and lowest VCG, thus the highest stability. The final load condition is "worst case" or arrival condition. In this case the tanks are at 10 percent, stores are depleted, but crew and owner's items are aboard. This means the boat is floating high in the water with a high VCG. Worst case stability is the final criteria. The stability of your boat safeguards the lives of you and your crew, thus it is worth paying attention to. The correct data for your boat can only be ascertained by the input of proven information. The vertical height of G, the center of gravity for the entire boat, is subject to much guessing. This is done because actually measuring the height of G is an elaborate undertaking. It is done by conducting what's called an "Inclining Experiment". This involves heeling your boat with controlled weights moved a measured distance and taking measurements of the angle. This data along with the hull lines and current floatation are the inputs required to arrive at real stability that applies to your actual boat. It is not good enough to state that an inclining has been done on another similar boat. These boats are now 20 years old and many changes (additions) have occurred. There may also be hidden differences in construction that can throw data off. The Fantail 50 has always appeared to me to be an unhappy vessel, to my eye they appear top heavy with too large and high a deckhouse. Also someone miscalculated the weights and they all appear noticeably down by the stern. Be aware that fuel consumption will be quite a bit more than 25 gpd at 8 knots, perhaps double that. To get the 1700 miles you will need to slow down to 6 knots or less.

I'm not >sure if this ballast was increased as the designer suggested. Jim, I believe that the righting moment of 120 deg. and 1700 mile range are, unfortunately, sales hyperbole in my opinion. The Fantail 50 is listed at 42,500 lbs disp. 3500 lbs ballast would be a ballast/displacement ratio of 8%. My boat has a ballast/displcement ratio of 21%. I don't have 120 deg. stability. Ballast/displacement ratio is NOT the absolute indicator of stability, but only one of many factors to consider. The ballast was never increased during the production of the Fantail 50. The designer told me he tought the ballast should have been increased several years after it went out of production. >We were also told that the Transworld 50' Fantale Trawler burns approx. 25 >gallons a day with a range of about 1,700 miles. Well let's run those numbers. The Fantail 50 lists fuel capacity at 520 gallons. If you divide 520 by 25, you have 20.8 days till all empty. 20.8 days is 499.2 hours. If you cover 1700 miles in 499.2 hours, then you have an average speed of 3.4 knots! Let's figure it another way. If you divide 1700 by 520 fuel capacity you get 3.3 nautical mpg. If you burn 25/24 or 1.04 gph, then multiple 3.3 x 1.04 and again you come up with 3.4 knots! These numbers are theortically possible but 3.4 knots in a trawler is little more than drifting with the currents. My gut feeling is that you will get about a 1200 to 1400 mile range at 6 to 6.5 knots with no generator or stabilizers, burning about 2.5 to 3 gallons per hour, or 70 gal. per day. Running stabiliz_ers and a generator could reduce these numbers. >Again, we really appreciate your feedback and now have some serious >considerations to resolve. Jim, I am not trying to talk you out of this boat. I just want you to have realistic expectations before plunking your money down. This may be the perfect boat for you, but be informed of its capabilities and limitations.

Thank you

for all your feedback.

You'll see above the information we get regarding

the vessel.

Yesterday i was able to correspond with Steve Davis about the

design and

stability of the fantail.

And there you have it, information
from a number of different sources and viewpoints.  That is what PUP is all
about.  I still stand by my opinion that the performance specifications
provided by the yacht broker are theoretically possible only at 3.4 knots with
no generator or stabilizers operating.  It is just simply a matter of running
the figures.

If you like the boat, buy it.

Good fortune,

One more check on the Fantail is the fuel burn rate.  The is NO diesel
engine that will produce 28 hp for 24 hours on less that about 45 gallons of
fuel.  Not the 25 gallons quoted.

Normal burn rate is 15 hp for one hour from one gallon of fuel.

NOTE - A gasoline engine requires about another 15 to 30% depending on the
actual peak pressure of operation, i.e. how open the throttle is.

Merry Christmas to all

Fuel burn---28hp at hull speed which is usually 1.34 X square root of waterline--If you use a s/l ratio of 1.1-1.2 as hull speed fuel burn decreases.

Kevin Kearney JOLIE with a hull that also requires 28hp at 1.34 but operates at 1.1-1.2 and has gotten 5.5mpg at.7.1knots on a 43ft waterline with fuel logs of over 100,000 miles
