Ok to Remove Inner Forestay?

Hi all, I am pondering removing the inner forestay on our 1981 Hunter Cherubini 37, simply to make tacking easier and give more room on the foredeck. Is there a structural reason that removing the inner forestay is a bad idea? Is it an integral part of the standing rigging? Could removing it cause the mast to buckle in strong wind?
You may be asking: why remove it? In the past 8 years of owning the boat we used the staysail only a few times early on to try it out, but have never found it very useful. Perhaps I'll face some criticism for not using the staysail more, and perhaps we simply are not 'salty' enough, but we sail mostly in summertime light wind in the Gulf Islands (inner south coast of BC, Canada), and we find it simpler and easier to primarily use our ~110% genoa on rolling furler and reef that as required if the winds picks up. A few years ago we removed the staysail boom to make more room on the forward deck and we don't miss it at all. There are two reasons we don't like the inner forestay. One is that it makes tacking with the genoa a royal pain. More than half the time the genoa simply wraps itself around the inner forestay instead of laying over on the new tack, and one of us has to run forward and help detangle the sail and/or sheets and move it over manually, a process that is both irritating and at times dangerous in moderate wind. The second reason is we like to stow our dingy on the foredeck for extended sails. Our current dingy just fits between the mast and the inner forestay, but we're looking at a new one that is slightly longer and won't fit in that space.
Being that I'm somewhat adverse to commitment, I was thinking of starting by detaching the inner forestay from the deck and securing it at the mast in some way to prevent halyard slapping issues, but leave the top attachment and deck hardware in place so it would be relatively simple to reattach if we for some reason regret the decision and want our inner forestay back.
I've attached an image with the forestay we are considering removing highlighted in yellow, just for clarity.
Any thoughts or advice appreciated!

Welcome to the forum! :beer:
No Hunter here, but I've sailed on Navy 44s and Nicholson 55s with an inner forestay that we would rig for heavy weather. Once back in calmer conditions, disconnect the Johnson lever and move the inner forestay to the base of the mast. I can think of no reason why you can't do the same.

There's nothing new under the sun... cutter versus sloop rig for the H37C has been discussed ad infinitum here. Try using the Advanced Search but here's a link to get you started:
37 cutter to sloop
Blaise Pascal was a big fan of converting to sloop. I, on the other hand, was not. There's no right answer. If I was sailing your home waters, I'd might consider removing the inner forestay and flying a big roller-furling genoa. There is no structural issue with removing the inner forestay.

I note that the running back stays connect to the mast right opposite the inner forestay and therefore balance forces on the mast. In really dire conditions that will make the rig much sturdier.

Many have converted the HC 37 to a sloop, including Blaise Pascal whose achievements are most respect worthy.

I have not. We sail on San Francisco Bay where afternoon high winds are the norm in much of the year. Furling the jib and reefing the main leaves you with a easy to sail, balanced self tending rig.

I overcome the issue of tacking the jib by using the roller furler if needed.

All that said, our down and light wind performance is not that good, so under other conditions I would be looking for a bigger headsail. I put a $400 quick release on my inner forestay and have never used it.

It should be mentioned that, on the Hunter 37 Cutter, the running backstays (aka checkstays) are used to prevent the mast from 'pumping' when in heavy wind with the staysail flying. If you are not using the staysail in such conditions, the running backstays are probably not needed. The cutter rig on the H37C is designed with a high clew 'Yankee' jib that is easy to tack through the gap between the inner and outer forestays; if you have a genoa or a head sail where 'J' measurement is greater than 100%, you will probably need to partially roller-furl the sail when tacking with the inner forestay in place. Finally, a true cutter rig is designed with the mast a bit further aft than on a sloop. The balance of your helm may change slightly (more lee helm/less weather helm) when sailing as a sloop with a large genoa. I don't know if Blaise Pascal is still active on this forum, but he would know more about sailing the H37C as a sloop than almost anyone...

On my 410 I added the inner forestay, obviously I could also remove it. I'm pretty sure you can remove yours.
My inner forestay is also furling, I would never remove it, use it all the time actualy.
I don't race anymore so rolling up the big Genoa for tacking is not a big deal, my inner sail pretty much tacks on its own.

fantastic and I never like partially rolled/reefed genoa in high winds.
None of this is necessary for local daysails so I understand your position.
Go longer distance, cross oceans you can put it back.
