Time Line - 1974: Captive Column Scuba Boat... |
This Captive Column Scuba Boat was built to show the design
flexibility of the Captive Column. Early objections to the usefulness of Captive Columns
included the rumor that fittings and attachments were difficult, if not impossible, to
design. As you can see in the photos below, this Captive Column Scuba Boat included many
fittings.
Mr. Bosch proved that designing fittings and attachments was a simple matter as he
continued to build more prototypes of Captive Column products.

The Scuba Boat main hull,
outrigger beam, and outrigger floats were of Captive Column construction. (20k) |
 |
Hatch cover, outrigger beam, and
rope attachment holes in the main hull shows the design flexibility of Captive Column
construction. The central section of the column/core assembly was reinforced to compensate
for skin filaments that were cut away for the hatch cover. (20k) |
 |
Outrigger beams slid into
fittings encased in the outrigger float. The outrigger beam also slid through a fitting
encased in the main hull, which permitted disassembly for transportation. Photo shows
craft prior to the application of the fiberglass surface coat. (23k) |

Outrigger beam handled torsion
and bending loads while permitting easy boarding of the main float. This photo shows the
finished Scuba Boat hitting the high seas. (10k) |
