I
have seen very few hard dodgers that I feel are
attractive or appropriate for the lines of the boat they
are mounted on. Most fit one of two categories: Snoopy's
dog house or
WWII
gun turret. Of the few I have seen that I liked, about
1/2 turned out to be inspired by the article I wrote 10
years ago for Cruising World magazine on how to
build a curved hard dodger. I was pleased and flattered
that my article inspired others.
I do not like the
"dodgers" that are at full standing headroom height:
usually just windows on the front of a bimini. This
almost always spoils the lines of a boat (assuming the
lines were attractive to begin with). As well, it means
you are always looking through windows when steering the
boat. Only glass will last very long without
becoming cloudy, but even it quickly becomes covered in
salt in adverse conditions. Peering through vinyl
windows while navigating an inland waterway is like a bad acid trip. Fellow
Traveler came with the traditional
separate dodger and bimini, and this just looks "right"
to me. As well, by merely standing up at the helm, I can
peer between the dodger and bimini for an unobstructed
view forward to dodge, for example, the clear plastic
jugs used as fishing trap floats around Martinique or
the huge logs floating around the San Blas following a
heavy rain.
My new hard dodger is
very much like the one I built for my previous boat,
Lobo, seen here.
To give you a quick rundown of how I molded this dodger,
I build a jig that consisted of a box made out of 2x10
pieces. I do not remember the exact dimensions, but
figure it was about 4x4. I cut two slits into two of the
sides of the box that would allow me to slide pieces of
plywood into them. I made the slits angled, one forward,
one aft, to come close to the approximate final shape of
the dodger, but this is not really necessary. The
two pieces of plywood were 3/4", but cheap plywood as they are only used as a form.
I then
screwed some scrap pieces of 2x4 between the two pieces
of plywood to lock them in place, and screwed some scrap pieces along the
edges of the 3/4 plywood to provide plenty of places to
screw down the thin plywood you will be molding around this jig.
You have, at this point, basically created a male mold.
You want this mold (or jig) to be slightly longer fore
and aft than the finished dodger will be. You will
understand why shortly. To mold the dodger, you want very
thin plywood. Ideally it should also be exterior grade
and very clear grain. Yeah, right. But, since I could
never get all that, I settled for clear, thin plywood
and figured the Epoxy it all gets coated with makes up
for the rest. Below is a 3D mockup of what the jig
should look like.
An aside on shape:
experts will tell you that you can bend plywood into
either sections of a cylinder or sections of a cone. You
can not bend it in two directions, so if you want a
WWII
gun turret dodger, you will have to chose another
material. But, the typical canvas dodger has these same
shapes, so if you follow my approach, most people will
not believe you have a hard dodger until they come
aboard and knock on it.
So, obviously, the
next step is to bend the thin plywood around the jig,
using various clamps and lots of pan-head screws (if
they will be removed) and flathead screws (if they will
be left) into the blocks of wood and 2x4's you have
provide just for this purpose. As you do this, remember
that any screws driven in the middle of the dodger will
have to be removed, so try to do most of the screwing
along the fore and aft edges, which as I noted above,
you make wider than you need. After the layup is
finished, you cut this area away as th ere will be screws
with the heads buried between layers. If your dodger is
large, you may have to put a seam in each layer. Try to
plan so seams in different layers do not occur near each
other and also have a 2x4 where the seam will occur so
you can screw, even temporarily, along the edge of the
seam.
After you have bent
the first layer, you hopefully have your technique down
because the second layer has to be put on fast as you
will epoxy it to the first. I believe I molded the first
dodger with just thickened epoxy between the layers, and
used three layers of door skin luan plywood. I coated
the outside with several layers of fiberglass cloth and
epoxy. Once it was all set up, I cut off the edges with
all the screws which seperated it from the jig. It will
want to spring out from the intended shape, but you can
put a 2x4 stringer or two in to hold it to the
correct width, held in place with a couple of pan-head
screws. This makes it much easier to transport the
dodger from construction site to the boat and into place
without stressing it somewhere. The stringers will
need to be higher than the cabin top the dodger will be
attached to so you can mount the dodger first, then
remove the stringer later. I mounted the first dodger with
three thru-bolts with fender washers to each side.
If you are a more
meticulous planner than I you can no doubt totally
finish your dodger in the shop (a parking lot, in my
case). I chose to mount the basic molded dodger, then
finish it en situ. I used thin strips of wood which I
layered up with epoxy to build up an edge on the forward
and aft edges of the dodger, letting them taper out as
the dodger faired into the cabin. This provides a
handhold on the aft edge and also directs any water off
to the sides. Windows were made out of vinyl and
Sunbrella like traditional canvas dodgers.
With Fellow
Traveler I had an existing dodger whose shape I was very
happy with functionally and aesthetically. So, instead
of having to build a jig I could use the frame from the
old dodger and save time. I used some scrap light line
to tie the dodger frame into place after removing the
old dodger. The first
layer
of plywood was bent around the frame in place. Small holes
were drilled on either side of the frame every few feet
and plastic wire ties were run through and tightened
down to hold the plywood to the frame. A layer of matte
and epoxy went over this, then the next layer of plywood
over that while it was wet. I used about 75 small
pan-head screws to screw the second layer to the first,
then backed them out once all was solid. If one
sheet of plywood is not large enough to form the whole
layer, then you want to stagger the joints. At the joint
you can lay a scrap 2x4, covered in plastic wrap, and
clamp it down thoroughly to hold the joint tight until
it sets up.
Once again,
strips of lumber was used to to build up both the
forward and aft edge of the dodger. However, I came up with an easier method of fitting these
edges,. I bought lumber in the dimension I wanted
(Colombia had very clear-grained cedar in a variety of
sizes: I chose 3/4 x 1 1/4"). I cut this into lengths of
about 18", used a grinder with a sanding disk to roughly
shape the bottom edge to fit the curve of the dodger,
then bedded each piece in an epoxy and coloidal silica
mix and screwed them down with two screws driven in from
the bottom of the dodger. More of the
epoxy mix filled in any gaps between the pieces and the
dodger or in the joints of the short pieces. Once the
epoxy is solid, the grinder was used to round the top
corners and shape the overall length to form nice
curves. Three long pan-head screws on each side mount
the dodger to the cabin sides. As the plywood is very
smooth, I did not cover the outside with any cloth, but
did paint both sides thoroughly with epoxy before
priming and painting with Awlgrip.
I chose to leave the
old stainless dodger frame in place, but honestly, I
wish I had added an extra layer of plywood and
eliminated the frame: it is very difficult to paint
around. I build my
dodger en situ, not worrying
about the epoxy drips as my next project was to paint
the cockpit, decks, and new dodger. Otherwise, I
probably would have build it in place, but used numerous
garbage bags to protect the boat. If I had a nice garage
or shop, then I would absolutely have mounted the frames
on a bench and shop-built the dodger, but being an
itinerant cruiser, that option did not exist.
I should note that
plywood is not the only material that can be used. Foam
core, balsa, or hex-cell could easily adapt to this
method... but try finding them in Colombia! As well,
veneer would work, that is, thin layers of wood. I might
have considered one of these methods if I sailed a
fly-weight catamaran or ULD sled. Since I have a
moderate displacement Morgan, I figured the few extra
pounds from the ply did not really matter much.
As you see from the
pictures, I again made windows out of clear vinyl and
sunbrella. Since the side windows are fixed, I might one
day bend some plexi and frame them in, but this was
simple and works. Since the dodger is rigid, the
attachment for the front straps of my bimini are now on
top of the dodger
If you have any
questions about building a dodger similar to this, fee
free to email me, I hope, in ten
years, I see many beautiful molded dodgers replacing the
huge greenhouse contraptions so many cruisers put on
their barges! |
