Hello rec.boaters. Hope all is well and everyone is having a good
season.

Bought a Larson 22' bowrider earlier this year and had a very
enjoyable summer of cruising and water sports with family and
friends. Couple of small warranty issues, but overall she proved to
be solid and I am pleased with the boat.

However, there is one thing about the boat that is driving me nuts.
The bimini top: How it is attached to the boat, how much it flexes the
windshield at the attach points, and how much noise it makes because
of the flexing.

During any kind of chop, the bimini oscillates port and starboard, and
causes the windshield sides to flex very noticably. It's flexing
enough that I am concerned about gelcoat damage at the windshield/hull
attach points.

The bimini is a typical stainless tube structure. The base fixtures
are well attached to the gunnel (aft) and windshield frame (forward).

Here's a stock photo, and I've added a crude wireframe diagram to show
where the bimini attaches:

When deployed, two straps attach to anchor points at the corners of
the windshield.

Here's another stock photo showing the detail just inside the
windshield. The gunnel is several inches wide. The green lines
represent what I think is a logical place to put some type of support
post. I think it would look bad, breaking up the clean lines of the
gunnel, but I am at a loss for what else to do.

Getting rid of the bimini is not an option. Too much 12 o'clock sun
here in the south.

Suggestions appreciated.


We have a 20 foot runabout and I installed the bimini myself. I attached
the bimini frame to the gunnel area outside of the windshield. I then
attached rubber spacers between the frame and the vertical fiberglass area
running under the windshield to the gunnel. Anchor points for the fore and
aft straps are attached to that same fiberglass area running under the
windshield.

I still get some sway in the frame (when not up or not deployed) but at
least it is not flexing the windshield as in your case.

As and easy fix you may want to put the bimini up (deployed) when running as
the forward and aft securement straps will stop the sway (at least it does
in our case.).

If you want I can post link to a pic of our setup.
