Over the past couple of years, as I’ve
been drawn into the world of boat design, I’ve made
a concentrated effort to confine my work to sail and human
powered vessels. I’ve been a mulithull sailor and
canoe/kayaker for a long time and have found most of my
experiences in that part of the boating world. My design
portfolio reflects that background.
Recently, after successive readings of the exploits of
many different guys and their construction of the nearly
legendary Tolman
Alaska Skiff, I was pulled into the potential
of designing a multi-purpose power boat. It wasn’t
just the Tolman form that enticed me so much. It was the
complete enthusiasm for the design and the potential that
the design represented to them in the pursuit of their boating
dreams, that got me all caught-up with the fever.
Like a moth circling a back porch light, I searched the
web and found dozens of references to the classic skiff
form that were available as finished boats as well as plan
sets for homebuilders. Gosh, there were ultra deep vees,
asymmetrical catamarans, mislabeled party barges, pseudo
Bass boats, flat bottom ski boats posing as off-shore hulls…Wow!,
the parade of hulls being offered as suitable for near offshore
conditions was bewildering.

After reading reviews and reports from experienced designers
as well as fishermen who used the hulls to make a living,
I settled in on the same form that is used by the Tolman
as well as several other successful designs for the application.
There were far more examples in the over 18’ range.
That makes a lot of sense, as the boat is typically used
for off-shore fishing and pleasure boating and smaller power
boats don’t do especially well in the bigger conditions
typically encountered, nor is it advisable to have a small
boat out in conditions of that sort. Virtually all of these
boats have strong vee sections forward with the angled deadrise
easing off and being carried all the way aft in varying
degrees.
Most
of the boats settle into a deadrise formula that finds something
in the neighborhood of 14 degrees amidships and around 8
degrees at the transom. Longer boats, with their heavier
weights are deeper in the water with stronger angles to
reflect their displacement needs.
I decided to put some time on my sketch pad and the computer
to pull together some of my own thoughts as to a suitable
skiff for near, off-shore and lake boating.
The boat had to be manageable for a single user, easily
trailered and launched and be suited for smaller water conditions
as one would find close to shore and in semi-protected bays
and lakes. I didn’t have the burning need to develop
a full tilt, enclosed wheelhouse or fully constructed forward
cuddy. I felt those design concepts were better handled
by the boats that were in the 20-26’ range with their
superior load carrying ability and size proportions.
I was more after a boat that could be used completely open
when the weather was nice and could have a soft, fold-up
cuddy cover for drizzly conditions or sleeping aboard. In
short, I wanted the top down convenience of a nicely performing,
convertible Grand Touring sports boat. One that handled
really well and could get up and fly when asked.

Since very few designs were available in the 16’
length, I settled on that size as the perfect fit for my
design criteria. She is 6’ 8” on the beam. The
Redondo Skiff is a boat that is simple to build, fast on
the water with her 30-50 hp outboard and can handle chop
with its pronounced vee sections up front that are carried
back to an 8 degree deadrise at the transom.
I really liked the incorporated spray rail chine that is
seen on several designs of this type for a lot of reasons,
so I incorporated a nice rail into the Redondo that starts
at the stem and sweeps back to the transom as it echoes
the shear. This rail does a couple of things for the design.
It deflects wave action and generated spray away from the
boat, giving it a drier ride, it really does a job helping
to dampen roll when at anchor and it provides a boost to
getting the hull up on plane when powered up on long rides.
The
penalties (there always seems to be some kind of penalty
for every design decision) are that there is an extra piece
to each side of the hull during the build and there is extra
wetted surface drag when tooling around in displacement
mode. I decided to take those hits and design-in the extra
chine for all the added benefits they provide.
The boat can be built with a standard steering position
to the side of the cockpit or with a centrally mounted steering
position if the boat is going to be used more for fishing.
The central position allows fishermen to freely move about
the hull perimeter while they have a fish on the line without
having to climb over the wheel and seat.
Actually, this whole, fishing around the hull, thing kind
of busts me up in a way. I fully understand the methodology
for the free access, but I have never seen an actual fishing
boat of this size that would allow you to move freely around
the boat. I mean, what with all the tackle boxes, beer coolers
and semi-dozing, grumpy teenagers who are typically on-board
for a day fishing trip, it’s just not going to happen
the way it is designed.
No
matter, just go by yourself.
The first boat is going to be built by a great guy out
in Southern California who is a math teacher by day and
a free diver and waterman on the weekends. As an avid surfer
and board shaper, he has had plenty of experience handling
resins and fiberglass, even if this is his first real boat.
So, the build process will be very straight-forward for
him.
He has two small kids, in addition to his wife, and he
wants to have the versatility that this design provides.
Even though he is initially building the boat as an open
craft, he can always construct a slightly raised profile,
foredeck to allow his kids a place to crash should they
hit the wall while out on the water, without messing with
the overall plan of the design.
Anyway, this is a nice boat for fishing as well as just
tooling around and enjoying the water on a nice day.
