a sail that is not trimmed properly creates drag. drag slows the boat and makes it heel more. it also disrupts the air flow to the next sail in line.
a genniker is for off wind sailing only. roll it up to a smaller size and it is awful in shape. it is for off the wind when the app wind is reduced as you are going with the wind. when you are hard on the wind, the app wind is increased and a smaller sail properly cut will help you sail the vessel to weather.
a sail is either pulling or dragging. drag is a big bummer.
on your vessel the set up is for you to use the smaller jib for beating to weather and the bigger jib to sail off the wind.
yes you can use both head sails wing on wing in a heavy blow down wind. prolly won't much out side of trade winds.
yes you can fly all three sails on a reach. prolly won't much being the keeping the air flow on the slots between the sails clean is an art form.
the smaller inside jib will be heavier cloth for the stronger app winds. the genniker will be a lighter cloth with the lesser app winds.
with a dirty bottom it is all mute. you are trying to sail a 4 barrel raft/ not much going to happen.
most modern cruisers do not sail to weather if they can help it. they will wait for the wind to change or turn on the iron jib. if that's you? why get the jib. the jib will be good in higher winds for reaching. a lot of modern cruisers will not sail in higher winds because ---------------------.
you fill in the blanks.
me, i would get the jib in a heart beat.
i sail to weather every time. i have my vessels set up to do such. it's a hoot to be able to drive to weather with skill.
in 62 years of sailing i have not gone five mile with the autopilot on. we drive the boat.
i carry 5 jibs, no roller reefing on my vessel.
1 Asail and 2 spinnakers and a crew to fly them all.
we sail when the wind blows not just when the sun shines
.... and we have loads of wind to play with.
these are wind toys, just saying
