My DW recently bought the same boat (H290), and I sail and race Albacore dinghies. On the Albacores, we used to use whisker poles on runs and Barber haulers on reaches. Then - with help from some international class rules amendments! - we all switched to "flyaway jib sticks" that we use on the windward side on runs and on the leeward side on reaches.
It's an aluminum whisker pole (usually full max legal length) with a control line running through it. Its aft end is suspended on a long bungee cord that runs through a block near the spreaders.
The aft end of the control line is at a cleat in the cockpit, and the fore end is attached to the clew of the jib. When we sail close-hauled, the line is loose and the pole hangs from the spreaders. (We pad them with "pool noodles" where they hit mast and boom. A few sailors have used small pieces of Velcro to hold the pole to the mast when it's idle.)
For running, the helm pulls on the windward jibsheet while the crew pulls the pole line all the way in and cleats it. The line runs through the whisker pole ring at the front of the mast, so it pulls the aft end of the pole down to that ring for running.
For reaching, we extend it only part way, at an angle that optimizes the shape of the reaching jib. At the broadest reaching angle, we can still easily get a lovely jib shape with the clew well outboard of the gunwale - impossible with a Barber hauler or a block on a toerail.
In both cases, when we want the jibstick to go away, we just uncleat and release the line, and the bungee pulls it up to its resting place. (Ideally, the jib end of the pole line is manually pulled out of the pole so it doesn't hook the clew like a tensioned lazy sheet. But that's pretty small stuff.)
We've only had the H290 since May, and lots of other jobs have had higher priority than perfecting the shape of our reaching jib. But I may try to transfer this great technology to the Hunter. (I've considered 2 lines rather than a line and a bungee.)
Of course, a more conventional telescoping whisker pole (or a spinnaker pole on a mast slide) would do the same job manually. But the flyaway version could all be led back to the cockpit.
