New Houseboats for Flagler Beach, Florida, Marina
Flagler Bridge Boatworks
and Marina in Flagler Beach, Florida, hired Sponberg Yacht Design in 2005 to
develop a series of houseboat designs for their marina.
The state of Florida has given the marina approval for the mooring of
41 houseboats in a variety of designs.
Flagler Beach is located about midway between Daytona Beach to the
south and historic St. Augustine (the oldest city in the United States) to the
north, straddling the Intracoastal Waterway where the marina is located. The marina is less than half a mile as the osprey flies to
the Atlantic Ocean, and about 30 miles both north and south to the nearest

will be optional on future models.

The following story reviews the development of the Flagler-style houseboats from their inception to the present. The prototypes shown in the first series of photographs were built on plywood and fiberglass barges, and a newer model has been developed for a molded fiberglass boat hull. For details on the new hull and house style, scroll down to the end of the article.
The Flagler Houseboats shown here are in two sizes: Small, 16’ x 40’ or 16' x 44', with about 550 sq. ft. of interior living area on one level; and Medium, 20' x 40', 20' x 44', and 20' x 48', with about 1,400 sq. ft. of interior living area on two levels. A Large version is anticipated, as are custom versions for discerning clients. This is a most affordable means for on-the-water living, and it is a full-time cruiser so it can be moved to other locations.
Each living unit is built on a
rectilinear plywood and fiberglass hull that is subdivided into several
watertight compartments. The
proprietary method of hull construction was developed by Howard Sklar of
Flagler Bridge Boatworks and Marina in collaboration with Sponberg Yacht Design to assure
high-quality boatbuilding standards and a long
life with the minimum amount of maintenance.
The project started with the building of a one-level prototype barge that included rounded corners on the exterior walls and an arched roof. The construction of this barge was used to work out the hull construction, building specifications, and techniques that would allow simple, high-quality construction.

the curved corners and curved roof are quite attractive, they are more
expensive to build than square corners and roofs.
These features are not included in the standard designs, but
an owner may request them for a correspondingly adjusted price.
The prototype floor plan
below shows an arrangement with living room, kitchen, bath, laundry, and a bedroom. There are access hatches
through the floor to get into the hull interior. Each watertight space in the hull has bilge pumps with
automatic switches. The hull is
ventilated at the ends to keep spaces dry. All
interior surfaces in the hull are coated with wood preservatives.

Each houseboat has
complete electrical and water services. There
are shore power connections for electricity, television, telephone, and the Internet.
Plumbing service includes fresh water supply to an on-board hot water
heater, and all gray water (sink and shower drains) and black water (toilet
drains) collect in an on-board black water tank.
The tank is connected to a sewage vacuum system at the dock that
can suck it free and dump into the Flagler Beach city sewer system.
No through-hull connections of any sort in the
hull are necessary, so chances of any spills or hull flooding are nil.

Another model that has
been built is the
small houseboat which is actually much larger than the prototype.
It has two levels wherein the
construction techniques for adding the second level were worked out.
Fig. 8. The
"Small" houseboat is built, in this example, with larger porches
on the second level. Compare this photo to the elevation below.
The small houseboat was
designed with square corners and a Mansard-style roof. Porches are at either end of the first level, and
another porch is at the aft end of the upper level.

the time the photos were taken, the interior of the Small houseboat was
still in the rough-framing stage, so there was not anything finished to
Fig. 10. The Small houseboat is much bigger than the prototype and includes a living room, kitchen, dining room, great room, and full bath on the lower level.
Fig. 11. The second floor of the Small houseboat barge has two bedrooms, each with double beds and ensuite bathrooms.
The master bedroom has a porch at the aft end. The actual model with porches for both bedrooms necessarily has smaller bedrooms. However, this shows how interior and exterior spaces may be traded off, depending on how an owner wants to use the houseboat.
LATE NEWS (June 2008): At Flagler Bridge Boatworks' request, SYDI has redesigned the houseboats to be built on fiberglass hulls. These houseboats will be 16' wide, 52' long, and have single-story accommodations with two bedrooms, one and a half baths, kitchen, living room, dining area, and with porches at both ends. The hulls actually look more like a vessel than a barge and so will have a more nautical character. Some of the new drawings are shown below:
Fig. 12. The new houseboat profile on the fiberglass hull. Outboard power is optional.
Fig. 13. The new houseboat plan is a 2-bedroom, 1.5-bath arrangement. If desired, it can also be built on the original plywood epoxy barge.
Interested owners are encouraged to contact Mr. Howard Sklar at the marina for more information on purchasing a houseboat, long-term marina space leasing, and customization inside and out to suit particular tastes. Customers will work with Sponberg Yacht Design to verify their specifications or to customize their layouts and styling, and we will gladly work with a customer’s own interior designer to include those all-important special touches. Propulsion power by outboard engine can be provided. Shipment to locations outside Flagler Beach may be made by the houseboat's own power, by truck, or by barge.
