Has anyone in here done that?
If so I would appreciate any advice, in particular what fittings/parts to use to a simply/neatly/safely a) attach the crossbar to the backstays; b) attach panel to the crossbar an c) prevent the panel and crossbar from rotation around the axis of the crossbar.
The panel with be a 215W Kyocera
, which measures 1 meter by 1.5 meters. The cross bar would go below the panel along the long axis of the panel.
The boat is in a remote
place so I need to carry all the parts
with me, hence the need to plan in advance....Thanks in advance.
As with any fabrication on a boat, it needs to be designed to withstand marginal conditions.
I have a 135w panel on a 49ft boat and I would imagine that 215w is too big.
I would suggest getting a smaller width panel for safety
Anyway, this is how I did it...
I have rod rigging
which makes the panel mount stiffer, however it should work with stranded rigging
but it possibly will move slightly more.
The mounting height is just reachable by me on tiptoes and misses the running backstays
by about 0.5 meter.
You need a bar running between the backstays and mount this with a fabricated clamp on the ends of the bar (the clamp should have 2 screws that screw the clamp into the end of the bar)
Then mount the panel longways between the backstays with the NOAA solar panel system. This will enable you to tilt the panel to spill wind when sailing and catch sun when anchoring
. You will need 3 NOAA clamps.
The NOAA system adds safety
as in an emergency
you can remove the panel in under 30 seconds with no tools.
I have seen other installations and often they are under engineered.
Perhaps thats what the other replies are about.
Hard to judge, but drag is probably no more than the practice of strapping things to the lifelines
