as Mark_from_Australia says - "it will be fine"
sometimes we worry too much
when beginning , one wants it to work - and not striving for perfection
if we are not racing or speed sailing - the ideal is NOT necessary
back in the day , many people rigged as follows
and had a lot of fun and there were MANY
over one foot extra - maybe so as not to hit the young lady

and yeah, i agree, a windsurf lesson should start at the beach with some equipment rigging
