I will not go through all the points.
I will take up on the last lines repeated below.
There are many circumstances when it is desirable (much safer) to be able to motor in either direction. One example that has occurred with the 18m proa is sailing up a narrow shipping channel and the wind drops and heads the course. It is much safer and faster to just motor on rather than taking time to shunt in front of a ship doing 20kts coming up your backside. There have been a number of other situations where it has been safer, faster or just more convenient to motor on the current track when wind drops. A true safety feature of the HP is being ablt to back out of a tight situation but if you are irons during the shunt, motoring is the safest option to avoid getting closer to a dangerous shore. In light wind you can motor sail on either tack if the motors have that capability. It can get very tedious in unsteady winds if you have to shunt to motor when the wind drops.
the 18mm proa has a preferred direction for motoring and in light conditions where sails are not doing much and zero risk to sail with wind over lee side we tack through the wind using the motors and continue to motor sail.

It seems on a HP, with a tilted tender, much of this applies to a more or less degree, right? Some of it not at all?
Should one assume a HP NEEDS to motor in either direction? Is there a reason I cannot see to assume bidirectional motoring?
