Mid-bow know-how
After you've built a horizontal main
frame, add a mid-bow. Mid-bows can
be almost vertical or angled depending
on the height and the aesthetic
you're after. Since we try to achieve
a minimum height of 74 inches at
the rear entry door, the top likely has
plenty of watershed angle already, as
most arches are taller than 74 inches. A
4-inch drop from front to rear is ample
for watershed (Photo 7). However, the
mid-bow should be positioned at threequarters
rearward on the main frame.
This allows a steeper angle of the
canvas top near the radius and prevents
puddling from occurring in the corners.
Additional details
Although conventional bow pockets
are customary for the rear of the
top and mid-bow tubes, sometimes
you'll want to secure the sides of the
top using snap-fl aps. Snap-fl aps are
typically 2.5-inch fi nished and are
sewn into the rain-fl ap (valance) seam.
They are attached to the tube using
rivet studs and conventional snaps.
Now the fun part: the enclosure
window panels! Be creative by offering
solid panels, glassed panels or smiles
and frowns (Photo 8). Often, we make
an entire duplicate set of the windows
in full mesh screen, offering the boat
owner a large screened-in porch
experience. For more information,
check out the Bimini Enclosure course
