Anywhere between 35 degrees and 45 degrees will work fine.
A: 32 degree angle
B: 45 degree angle
There is about 2 inches of clearance from the boom to the solar panel.
Two inches is fine for clearance.
The boom, this time, is with the main sail raised.
The topping lift loose.
The outhaul is all the way back. (if we loosen the outhaul the boom falls).
We are pulling down on the boom. This all means with the solid boom vang installed the boom will not drop lower. If we slacken the outhaul the boom will not drop if the solid boom vang is installed.
They attached a main sheet block to the top of the boom vang below the boom for a better fair lead back towards the traveler. Their boom vang line is led aft to the cockpit.
We went to Home Depot an looked at solder as that is what Garhauer recommends to make a template of the mast and boom. It was way expensive at Home Depot so we opted to use some SS bailing wire. Mark at Garhauer has the mounting plates for the Islander Freeport 36 as there are some that have already installed the Garhauer solid boom vang. Our 40 year old boat probably has the original mast and boom. However just in case something is off we sent (emailed) Mark the pictures to see if we are in the ball park.
