Glen-L Update
-
Website:
-
Web site:
The following are some of the changes made to
Glen-L.com since the last WebLetter.
-
The "Inboard" section of the Boat
Design Catalog has been updated, with
additional drawings and bills of materials.
The last section to be updated will be the
"Work Boats". We hope to have this
done before the next WebLetter.
-
On some of our design pages you will notice
"Notes" links (next "Bill of
Materials" and "Photos" links).
There are very few of these at present, but we
will be adding more in the future. Most of
those now on site have been answers to
specific questions from builders; some concern
performance, some show detail drawings.
-
As always, many new photos in "Customer
Photos" and new entries in the
"Project Registry". Thank you all
for sharing.
-
The PEDAL-IT plans and patterns are now available;
see below for details.
-
Shopping cart. Hope to have this ready by the end of
the year... we'll see.
-
When was the last time you visited the Boatbuilder
Connection? The Connection is meant to give you a
chance to talk to other builders about your
boatbuilding concerns. We would like to thank all of
you who have shared your expertise with other
builders. Builders like Mark Bronkalla provide
thoughtful, in depth answers that are well worth
checking out. Thank you Mark and all of the rest of
you for helping our boatbuilding community.
-
When you look at this WebLetter you may notice that
the majority of what we publish comes from builders
just like you. Some of the entries are
"how-to", but many are reports or comments
about their projects. This "real life"
feedback provides the best answer to whether "I
can build a boat". I hope you will share your
experiences with your fellow builders.
-
Tell us about your Glen-L sailboat. In a future
issue I would like to post comments on as many
Glen-L sailboats as possible... performance
summaries, articles on building, perhaps just:
"Built the Glen-L 14 from frame kit, took 8
months part time, performs great in all
airs"... or whatever. Email your report whether
the boat was just completed or finished 10 years
ago. List subject as "Sailboat report".
-
Marketing. The whole point of having a news letter
is to sell more stuff. This is a point I frequently
forget about when preparing the WebLetter. I usually
ask Darla.. "do you think this is enough, do
you think people will find this useful", when I
should be asking if she thinks we will sell more.
Anyway, I have noticed that I have again neglected
the marketing part, so if you enjoy this WebLetter,
buy something, and tell a friend about us. Since
Christmas is coming up, you might want to put a
fastening kit or gallon of Poxy-Shield on your
Christmas list. It will save your family a lot of
hectic shopping and you will get something you
really want.

At last... The Pedal-It plans & patterns are ready
In answer to all of you who have
asked when the Pedal-It would be ready... it's ready now.
For those new to the WebLetter, the Pedal-It is a pedal
powered boat that uses stitch and glue construction and
scavenged bicycle parts to make a twin hull boat that is
propelled by human power. There are lots of pictures of the
construction in the New section of
our website.
The Pedal-It plans and patterns are
$63.00. Order your set today!
Feedback: Flying Saucer
All and all, this was a very fun
project. From the time it (frame kit, fastening kit, and
fiberglass covering kit) arrived to completion was about
7 weeks. I work full-time so there were lots of late evenings
and weekend project time.
A couple of things to note. (1)
There was a little damage on one of the ribs at delivery;
looks like it (packing crate) might have been dropped. Easily
fixed, no problem. (2) I bolstered the transom with two
additional knees to support the weight of the Honda 25hp that
I put on it. (3) I located the wheel at a point closer to the
bow due to the weight of the motor. I had heard on the
Internet that another person had suggested moving the wheel
toward the bow. I guess with a lighter motor it would be ok
as spec'd.
The boat is really fast. A
couple of jet skis came up beside me last weekend as I was
just cruising. They took off and so did I. They were left in
my spray. Lots of fun!
Thanks for the project and when late
Winter/Spring rolls around it will be time to build another
one.
Sincerely, John T. Dutton, Media, PA
Mr. Dutton sent a large number of photos
of construction, we are including a few to illustrate the
construction and have added captions.

Class CD: Father/Son project
Wed, 25 Oct 2000
Hi, my name is Adam Twiford. I have
recently bought a Class CD Racing Runabout (frame kit,
bronze fastening kit, epoxy fiberglass kit). I started
building it in early September and have come quite a long way
on it considering that we have only put in about 40 hours.
Your plans and frame kit make the boat quite easy to build
and because of the epoxy resin it is as strong as rock. I am
13 years old, and the boat is pretty much a
"Father/Son" thing. We have decided to paint the
boat yellow with black racing stripes and we are going to
name it "Yellow Jacket". We have pictures of it in
the box all the way to it being completely covered in
plywood. We are fiberglassing it (probably the hardest part)
and will continue to take pictures until I am taking it on
it's test drive. I will probably send some pictures of it
to you and I would appreciate it if you would put them up on
the website. It would be really cool to tell my friends to go
to your website and see me in it. I am starting to like
building boats and I will probably never buy a company boat
in my life. It is too much fun to build it yourself, and
cheaper. Thank you for giving me the opportunity of building
my own boat and such a good one. You will probably receive
pictures in about 2 months of my boat.
Thank you
Adam Twiford
Rigging Small Sailboats
In response to inquiries about an
out-of-print book published by Glen-L, we are starting
a series in our WebLetters, reproducing Rigging Small Sailboats. This issue
contains Chapter 9; to be continued in the next
WebLetter.
Chapter 9
.....rigging the boat
FIG. 9-1 - Putting the
mast in position is called "stepping the
mast". With the pivoting mast step shown
in this boat, the mast is placed in the step
with one person pulling forward with the
forestay or jib halyard, and a second person
pushing forward and steadying the mast.
|
STEPPING THE MAST
Stepping the mast means
putting the mast on the boat so it can receive the
sails. Fig. 9-1 shows a mast being stepped on a
small catamaran. Since the first time you will step
the mast will probably be on land, the first thing
to do is make sure there are no overhead
obstructions in the way, ESPECIALLY ELECTRICAL
WIRES! Also, the mast stepping arrangement must be
in place. On boats with wood spars, there must be a
way for any water that may settle in the mast step
(either from rain coming down the inside of the spar
or from water on deck) to drain out, or rot will be
promoted. With aluminum spars, the same applies, but
not for the same reason. While stainless steel and
aluminum are fairly compatible, there is still some
corrosive action between the two in saltwater
conditions, and because the fastenings at the mast
base area will probably be stainless steel,
corrosion could occur if salt water were allowed to
remain between the two metals.
If the mast is of the
aluminum pivoting type, a stiffener is often used in
the base to provide extra bearing for the pivot
bolt. With pivoting masts, it may be necessary to
radius the bottom corners of the spar to allow it to
pivot into position. When wood masts are used in
conjunction with a pivoting mast step, the mast
should not bear directly on the deck or cabin top,
but should be supported by the large bolt in the
mast step fitting, thereby preventing rot by water
staying in the step. To raise a mast with a pivoting
mast step, insert the bolt through the mast in the
step, connect the shrouds to the chainplates
initially if possible, have one person aft and under
the mast pushing up forward, and have another person
pulling directly ahead with the forestay or jib
halyard.
Most masts are stepped with
some degree of "rake", or angle from
vertical when viewed in profile. This rake may be
built into the boat, but usually the builder must
align the mast to the proper rake. With masts that
step onto the keel or through the deck, wedges of
wood can be used at the hole through the deck to
maintain the angle along with the tension of the
stays. On masts stepped on deck or on the cabin top,
the rake of the mast must be maintained by stay
adjustment. Mast rake is usually noted in inches per
length of mast, and should be maintained per the
designer's specifications for proper
performance, at least initially. One method of
determining the rake is to affix a line to the top
of the mast with a plumb bob attached to the lower
end. The boat must be leveled first. The line should
be the length of the mast from the masthead to the
base point from which the rake is measured. The rake
is then measured from one side of the mast to the
plumb bob line. When the correct distance is
obtained, the stays can be set up. To keep the plumb
bob steady, it can be dropped in a container of
water. Another method for determining mast rake is
to make up a shim or template equal to the amount of
rake. Then use a builder's level held vertically
and tilt the mast so that one side aligns with the
shim held between the level and the mast. Again, the
boat must first be leveled.
FIG. 9-2-How NOT to
adjust tension on stays. Tension should be set
up so that the spar is free of curves or bends
when sighting up along the length.

Feedback: Monaco
Mr. Yonescu has built both the Monaco and
Riviera. See Customer Photos/Photo Board 1.
Thanks for posting the Monaco,
it's nice to see both my boats on that "front
page". It's OK to keep my email address on your web
page, I do get email and answer all that write. It would be
nice to hear from someone wanting a boat built for them,
something like the Stiletto would be fun.
WEYonescu@flashcom.net
The 19K$ covers everything,
including 1K$ for the final clear coat spray (done in a booth
by a local auto body shop) and 1K$ for the upholstery (done
by a local auto upholstery shop), 1K$ for the complete
windshield, $500 just for the bow light. 1K$ for a fancy
CD-Stereo system with Bose speakers, separate amplifier and
powered subwoofer and dash mounted remote. There is a digital
compass, a digital depth-finder, and other fancy gold plated
gauges (Faria) that were more expensive than may really be
required. I used a custom 40 gal fuel tank ($350), about $500
for 10 coats of 2-part polyurethane clear as a pre-finish to
the final spray, $500 in epoxy. About 1K$ for the underwater
gear (available from Glen-L) and propeller. (I used a chromed
rudder, strut and stuffing box.) $200 for a Mahogany steering
wheel.
The bottom is 4 layers of 4mm Okoume
plywood (approx 12 4x8 sheets) ($400) Sides - 2 layers of 3mm
Okoume plywood (8 sheets ) ($300) with a final layer of
1/4" mahogany ($500). Deck - 5 sheets of 3mm Sepele
plywood ($350) over 4 sheets of 9 mm Okoume ($250) The bottom
got 3 coats of epoxy, 3 coats of 2-part barrier paint, and 2
coats of white bottom 2-part epoxy paint. Sides and deck were
stained, covered with 3 coats of epoxy then the 10 coats of
2-part poly, sanded and sanded and sanded and then the final
spray coats. The stringers were laminated out of 2 and 3
layers of 3/4 fir. Engine logs solid 4"x4"
mahogany. The engine/transmission cost approximately $7K. All
hardware was stainless steel. Other items make up the rest.
All these number are approximate. I
wanted the nicest boat I could build and didn't spare
expenses. There would be lots of ways to cut costs and still
have a very nice boat.
I hope this is helpful -

Let's see if I can tear up this man's design...
Subject: one of your boats
Date: Thu, 13 May 1999
From: Shelby Dean Aaron
To Mr. Glen L. Witt,
I purchased your 22 ft. Hunky Dory plans for aluminum in 1991
to build a rugged, simple, dependable boat. I now have a
computer to see your site... the world turns, does it not.
Anyway, I believe I have a humdinger of a testimony about how
idiot-proof your designs are. I built the craft with the
intention of making a sensible fishing boat. I welded it up
with a 3/16" hull and center console. But along the way,
somehow I ended up with a 150hp Mercury V-6 on it. After I
realized what I had done, I said, well let's see if I can
tear up this man's design. I'm here to tell you that
your craft are immune to crazy people. I have made by
accident, this 22 ft boat fly like a bird; to say it is
extremely fast is putting it mildly. We have even driven it
(accidently) upon parked black barges at night, that just
appeared. That was not me, but a buddy who did not have the
halogen lights on... go figure. I know a man of sound
judgement like yourself, and your fellow professional
designers would not do this, but we have not had the first
leak on the hull. ...The pictures I took in '91, before
the initial launch.
|
P.S. The boat was just sitting idle in the driveway one
day, when a tug captain who had hurt his back and was
disabled, wanted to know what I was going to do with
the boat. I asked why and he said he could haul
groceries to the area tugs and support his family. So I
sold it to him 6 years ago, with the 150 on it. It is
working 7 days a week on around the clock call, still
to this date. By the way, it was the tugboat captain
who was trying the boat out upon purchase, with me in
it; after I said not to turn this boat at wide
open throttle, did so. Ha, you ought to see how a 70
mph boat stops in less than 1/2 boat length after it
comes down from being airborne. I doubt Boston Whalers
could stand up to this punishment.
I just thought you would enjoy my note about one of
your vessels. It is all verbatim and true, as I have
said. Shelby Aaron

Glen-L builders in the news
Two builders of Glen-L boats were featured
in the "Launchings" pages in WoodenBoat magazine,
Sep/Oct 2000.
"Working with epoxy and okoume plywood, Willard
Dixon built this duck-gunning boat to Glen-L
Marine's plans for the Duck Boat Too. A 4-hp Yamaha
outboard powers the 12' 100-lb skiff. Willard
reports that the boat rows well, and he finds it
'satisfying all around'. You can reach the
builder at 5 Belloreid Ave CA 94901."

"Glen-L Marine designed, and Joe Luttrell built,
this 16' center-console skiff. Cayman II's hull
consists of fir plywood sheathed with fiberglass. A 48
Special Evenrude supplies the power. Joe Luttrell, 160
Carabell Dr., Huntsville, AL 35803"

Making a fiberglass shaft tube, daggerboard trunk, spar tube
We are using the construction of the
daggerboard trunk for the Bull's Eye to explain a
procedure that can readily be adapted to a variety of
projects, including non-boating applications.
-
Materials required:
-
Polyethylene plastic film.
-
Newspaper or card stock.
-
Form (in the case below, a daggerboard).
-
7 to 10 oz. fiberglass cloth, cut in widths at least
3" wider than the desired finish piece is long.
-
Poxy-Shield epoxy resin.
-
Gloves.
-
Wrap card stock or newspaper around the daggerboard (about
1/16" thick) and tape in place.
-
Wrap one layer of polyethylene sheet plastic over the
newspaper and tape in place. (Resin won't stick to
polyethylene.)
-
Clamp the daggerboard in a horizontal position with the
covered end readily accessible. Put newspaper underneath
to protect the floor from dripping resin.
-
Put on gloves.
-
Tape one end of the fiberglass cloth to the form and wrap
one time around daggerboard form with additional cloth
hanging down.
-
Wet cloth resin and wrap around an additional layer,
wetting out as you go, pulling the cloth snug to the form
with each turn. Continue to a total of about 5 layers.
-
Smooth the cloth with hands and squeegee, wringing out
excess resin. The laminates should be translucent, white
spots indicate that the cloth is not completely wet out.
-
After an overnight cure, slide the fiberglass trunk off
the form. The piece will be trimmed to length during
installation.
In the case of the daggerboard
trunk, a hole is cut in the bottom of the boat to match the
outside contour of the trunk. The trunk is slipped into the
hole, held in position, filleted in place, and the fillet
reinforced with cloth. The trunk excess is trimmed off on the
outside and ground smooth.
If you were making the PowerYak or
Electric Drive Mount, or the shaft through-deck supports on
the Pedal-It, the mast tube for the Eight Ball-SG, or prop
shaft tube for the Amp Eater, the procedure would be the
same.

Do not fasten your frames to your building form in a way that
you can't remove the screws after you have planked the
hull. Don't ask how i learned this trick.
I am a first timer, but didn't think I could be so
stupid.....

Gail,
Please leave me on your mailing list. I have just about
completed my Flying Saucer that you shipped mid-July. This
past Saturday and Sunday I was in the water for the first
time. WOW, does it move. I have a HONDA 25hp on it and it
moves... What a great project. Didn't do much for my
marriage of 30 years, just kidding, but ended up with a great
boat. This boat is faster than a jet ski, unbelievable.
Almost airborne.
Thanks for sending this reminder so that I could write back
to you.

From: Ibsen Stephan (Brazil)
GLEN-L MARINE DESIGNS
In the year of 1975 I built the GUNG HO, a 28' express
cruiser, built in plywood, and powered with twin
inboard-outboard motor of 130 SHP each.
Afterward, in 1987, I built the ODYSSEA, a 36' cruising
yacht, built in STEEL and powered with a single diesel engine
with 150 SHP.
Now I am studying the plans of other GLEN-L boats for STEEL
construction, and powered with one or twin diesel
engine.
The goal, is to fish in head seas and sometime powerful
wind.
I am in doubt between the ANDANTE, 38' yacht (build in
steel) and the MARAUNDER 44' Sport Fisherman build in
steel too.
I receive, last week the MARAUDER Study plans.
Now I need the study plans of the ANDANTE.
Thank you for your attention.

Note: Mr. Ibsen modified the Odyssea plans
for steel. We do not offer a steel version.

Comments: i really like your site. im building a boat at the

a boat like your step by step pictorial guide with captions
on building boats with ply.
email:
hello, i was wondering if you could tell me what the degree
of the vee at the bottom of the hot rod is. a representative
from glen l told me that it was too flat for a jet, but the
design catalog description says it is a vee bottom. i figure
i can find out what some jet manufacturers say is OK and then
go from there. if i am stuck with v-drive i guess that's
the way it is, but i'd really prefer jet if it is at all
do-able. thank you so much for your help. Matt holmes
ANSWER
-
4 degrees @ the transom
-
A flat bottom: the Sissy Do
-
A modified vee or vee bottom: Hot Rod, Thunderbolt, etc
-
A "flat bottom" when referring to a ski or race
boat: Hot Rod, Thunderbolt, etc
-
A deep vee, 12 degrees or more: Rampage, Roustabout
-
Performance: The best performance is a rear mount,
v-drive. A jet will not compare.
-
Even though not considered desirable, several Thunderbolts
have been built with jets... they "get by".
-
Manufacturers recommend 12 degrees or better. When the
boat is on a plane, a "flat bottom" tends to
lift completely out of the water, starving the pump of
water. No water= no thrust, no steering. Deep vees do not
come completely out of the water insuring a constant
supply of water (also more drag).
