I want to mount my Nova electronics brick on my Nacra F16.

Width: 125 mm ≈ 4.92″
Height: 80 mm ≈ 3.15″
Depth (thickness): 26 mm ≈ 1.02″

--Top of the spi pole will not work as there are jib adjustment lines that run on top.

--Mast mounting means I cannot see the electronics when mast rotates.

Have been thinking of mounting it on the front crossbar using the slot to anchor a plate that I can then use 3M velcro to hold the electronics in place on the plate. Suppose a square bolt head or something to anchor in the cross bar slot must be out there.

Maybe bottom of spi pole but hard to see.

Any advice? Thanks in advance.

Most people mount their electronics (Vakaros in my case) in front of the forestay on the spinnaker pole
