ROBERTS 434 Version A
The Roberts
434 boat plans come with a variety of sail boat plans including sloop (shown) cutter
and ketch. Other rigs are possible to suit your personal preference.
Hi Bruce, I studied calculus & Differential equations
but it still amazes me as to how accurate your drawings are. Everything
is coming out to within a 1/16th of an inch. I received the boat plans on
Labor day and presently I have the stem completed, the keelson completed
and will begin to install the first layer of stringers. I will go and
develop the photos that I have and send them to you.
I built an 8' x 8' work bench to build the
mould frames on and then tore that one down and built a 2'-8" x 16'-0"
work bench to work on for the remaining parts. I believe this saves me
many hours of labor verses crawling around on the floor ( I too old anyway
for that). I also took 1/8" hardboard and made master full size patterns
of the mould frames first.
This was to improve accuracy and for future
ease of cutting the bulkheads.
I find myself already wishing I was building a
65 footer so this very likely will not be the last design you sell to me.
Don't forget to send me some names of others working on similar projects;
I want to pick their brains for places to purchase materials at really
good prices.
Have a Great Day! Earl Rentmeester
Hi Bruce,
As you may
recall, we were having some trouble sailing our yacht because I am not
at all experienced. Well. I
guess we found out that we have a pretty fast boat. We achieved 9.3
knots in 17 knots of wind and are very pleased. Does that sound
about what you would expect from your 434 design stretched to 47'-9"?
Have a spiffy
G'Day Earl
Bruce says:
Very creditable - You are getting the best out of this fine boat,

ROBERTS 434
WOOD EPOXY
A FEW MONTHS
LATER !!!
Hi Bruce,
Here is an update on my boat
construction of your ROBERTS 434 B. The more I get into this project the more I am
admiring your skills as a navel architect. I just realized that the engine
can be made to easily be pulled up thru the cockpit floor without damaging
the rest of the vessel. Fantastic!
When I attended the Chicago boat show
last winter, I did not see that at all on the factory models; in fact the
engine compartment was so compact, I pitied the mechanic that had to work on
it. ... Have a Spiffy Good Day! Earl Rentmeester
UPDATE - AUGUST 2014
HI Bruce,
I just thought I should mention that every marina we enter, our boat is the
star attraction. Many people have asked me what name brand boat I have
because they would like to purchase one. We have got so many compliments
that I cannot number them.
Just last
weekend a fellow said now that is one cool sailboat and another heard him
say it and he replied you got that right. All the people in the marina
usually come over to view our boat.
So you get a feather in your hat
Bruce! I only lowered the pilothouse roof to make it more racy and sleek
looking and changed the stern to a sugar scoop. The design remains entirely
yours, Bruce and I tell everyone what a great designer you are.
We have only
been out in 8’ seas and the boat handles very smoothly and takes the seas
with ease. It was nice to hear from you again. We recently got our 6 cu ft
chest freezer to come one line and it works perfectly. We have a separate
4.5 cu ft refrigerator. We were handing out ice cream bars to the other
gunkholers.

NEW CUSTOM
FEATURE:
SAFETY SKEG IS
AVAILABLE ON THIS BOAT.
The Roberts safety skeg is designed to take the best features
from the LONG FIN / SKEG combination and add a SAFETY FACTOR. Many of
you may be aware that skegs in general are vulnerable to damage so here is
our answer to this problem.

ROBERTS 434
SINGLE HANDED AROUND THE
WORLD.
COPY OF LETTER FROM MR PAT GARNETT
Dear Mr Roberts, A quick note to let you know
that I have finished my circumnavigation in the Roberts 434.
She took 218 days and 8 hours
sailing time to cover the 27,000 miles, In terms of elapsed time this is the fastest E-W
ever by any kind of sailing vessel, but of course we do not get the world record as
Guinness work on average speed and she was half a knot slower than the "Ocean
Bound" (David Scott Cowper) nevertheless not bad for a backyard building job.
She is in excellent condition and could go around again
given a bit of sail repair. She is very fast for a heavy boat (3 tons of stores). She
often reached 10 knots and could sustain 9 knots for hours on end.
Her best day's run was
210 miles without current assistance. Her directional stability is excellent and in good
conditions to windward she can hold her heading unaided for up to 20 minutes. I had one
knockdown to 90 degrees and a few bad broaches but she picked herself up without
difficulty.
She is a superb boat, indeed she has to be to bring an incompetent single
handler like me home safely.
Best wishes to you and many thanks for a fine design. I
am starting to think about something in the 60-65' range. Yours, Signed, Pat
Garnett. |

FROM ROBERTS 434
OWNER:
Bob Isaacson writes:
"I just bought a Roberts 434 pilothouse. I brought it down the coast of Washington,
and hit some rough seas at the mouth of the Straits of Jan De Fuca.
The boat was GREAT, my
friends that sailed a Downeast 38 from NW to Fiji and back said "The Roberts 434
has a great motion. It is cutter-rigged and we sailed it into Greys Harbor, across the
bar, in about 10-20 kts of wind, it did fine.....I
LOVE IT!!! |

Bruce:
We have built your Offshore 44 design in steel are very happy with her.
She is a wonderful, comfortable and well sailing boat. We want to enter a
couple of low key races this year with her before we go off cruising. One
of the questions on the handicap form is the year that she was designed.
What year was she designed anyway? We started construction in 1985,
launched in 2002 and have been enjoying her ever since.
For your enjoyment I have attached a photo of her taken last September in
Tamales Bay, about 50 miles north of San Francisco.
Thanks for such a great boat.

This illustration shows the male hull mold
covered with either thin pre-laminated fiberglass strips or inexpensive plywood or hard-board followed by the
inner fiberglass laminate, next either foam or balsa core and finally the
outer layers of fiberglass. Note the area of the keel is not cored but has
additional fiberglass laminate to provide maximum strength in this area. |
|
On the left we see the C-Flex Fiberglass being installed on a hull mold
as described above. Similar methods are used to install core material such
as Corecell or Airex foam.
On the left
we see hull rolled over to the upright position and then the mold is lifted
out of the hull shell. The mold is sometimes removed in one piece as shown
here or in parts depending on the shape of the hull and the method used to
laminate the hull.

ROBERTS 434 TO
ICELAND: Hello Bruce Just thought you might be interested to know we were paying
customers on a Roberts 434 sailboat in Iceland this year. Our skipper Ashley Woods
had built the boat, 'Bold Explorer' himself. Bold Explorer felt extremely
sea kindly and
safe, and was simple but fun to sail. She has a large deck saloon which allows you to see
the horizon from inside the boat, a great boon on the colder days. We felt confident
sailing her around the wild and beautiful North West coast of Iceland up to the
Drangajokull glacier. I think Ash is intending to go back to Iceland this year, and also
to Norway, perhaps to the Lofoten Islands. (We have no financial arrangement with Ashley,
we were just happy with the trip). Yours Lesley Whitfield and Paul Brittain Ashley's

ROBERTS 44 OWNER: Bruce I have owned a Roberts 44 for
over 10 years. The boat was built in Hong Kong, the original owner was Halsey.
"Andale" is her name, when I bought her she was suffering form a bad case of
neglect. I repaired and refitted her over a period of 5 years. We lived in Sausalito
aboard her for 6 years, then sailed her to Mexico, where we have sailed her in
Mexican waters for the past few years. We have sailed her in all kinds of conditions, some
a little rougher than we like, but she has always come through. I want to thank you for
designing a boat such as her. In most all the anchorage's, she is always the most
beautiful. We get a lot of compliments, she makes you feel good just looking at her. Any
information you might have it would be greatly appreciated. Thank you again for designing
a boat such as Andale'

RAPID
RESPONSE:
CHEERS BRUCE, I Received your study boat plans some time ago, But I haven't had
time to Thank you for your rapid response. So thanks Bruce, the boat plans are a good carrot
for me to chew on while I start to save for Boat Building . My choice of boat would
be the Steel hulled 434,There's a couple of my Diving Buddy's at work on their 434's as I
write this E-mail Today. Both boats look pretty impressive, I can't wait to start on my
baby. Thanks S.J.Robinson. |
MOVING BULKHEADS: Good-Day BRUCE On the Radius chine 434 version C
that I am building I noticed that there are a number of bulkheads that need to be fitted.
Are all of them required as I would like to have a more of an open plan interior. At
present I have completed the frames and fitted them to the strong-back and should have the
stringers fitted by end of May. I did not realize that boat building could be so
simple. Lastly I must congratulate you on the quality a simplicity of the boat plans they are
easy to read. Regards, Johan Boes |
ROBERTS 44 built in Poland:
We recently had a letter from Andrzej Povsko who built a Roberts 44 in Poland....
Andrzej writes: In 1985 I built a boat in Poland, the plan was a Roberts 44 (your design).
I sailed a few seasons in the Baltic Sea and the North Sea. In 1989 I sailed from Europe
to the USA. The yacht is absolutely perfect, strong, fast, seaworthy and very dependable.
I felt very secure in the boat and very satisfied. Sincerely, Andrzej Povsko |
ANOTHER
ROBERTS 434: Dear Sir, A customer of yours named Lou Hunter built a 434 in Alameda,
CA and they left for Mexico and points south in Nov. 1998.You'll be glad to know that Lou
did a beautiful job, the boat was comparable to what very top quality professional yard
would do. I haven't heard from him since he left, but he was an experienced cruiser and no
doubt he and his wife, a very nice lady (whose patience I have great admiration for), are
enjoying themselves greatly. He said the boat was very fast but was very comfortable and
felt very secure. The name of the boat is "Tin Can", if you hear anything about
a boat by that name you can bet it's Lou's 434 because I don't there's anyone else in the
world who'd give their boat a name like that!!! Some day I'm follow Lou's example,
although I may opt for a larger boat. Regards, Paul Braga Note from Bruce.....If you
see this boat or any other Roberts 434.....let us know....we would like to hear from you. |
OWNER /
BUILDERS COMMENTS: Dear Bruce
I have owned a Roberts 44 offshore for the last few years
and its has proved itself to be a great boat. This year it gets a new set of sails however
I do not have a set of sail boat plans for it and I am wondering if they are still
available. The boat is cutter rigged but sailed mostly as a sloop. Any information on any
upgrades to the sail plan to improve performance would be appreciated as
well. Great web
site. Keep up the good work.

COMMENT
ON R434 boat plans: Dear Bruce, I received the Roberts 434 boat plans and reviewed them
thoroughly. They are very detailed and I am very pleased with them. I'm sorry I haven't
e-mailed sooner; my computer has been down for two weeks. Meanwhile, I have been
constructing a shed and a gantry for the project. I hope to progress quickly with the
beginning phases of construction. I have finally found a steel supplier that has
low-carbon steel. They are Toll Metals in Atlanta, Georgia. In your book, you recommend
sticking to one paint manufacturer through all of the finish. Can you recommend any paint
manufacturer who supplies primer like Sigma-weld), as well as finish paint? I plan to
blast and pre-prime the steel as you suggest, so I need to think about a primer that will
be compatible with the final finish. Thanks again for the awesome boat plans. I'm sure I will
have more questions in the future Thanks again, Andrew Flips |
