Well, equally, is there a future for the H2?

There very different animals aren't they?

The Aero obviously has a future, and the 9 will attract an audience based upon the theory that if you're large extra sail area is what you want - I've made my thoughts on that clear.

The H2 doesn't have RS marketing behind it and while it was aimed at a specific audience and to get around specific problems that singlehanders suffer from its far from an easy boat to sail. So yes, it has a future but it in my view it'll be another RS300 with a niche following.

If you look at the races recorded on the PY table its one of the most popular classes in the country, so I'd say the answer is definite yes. Similarly with such a large body of data the yardstick calculation is going to be a decent reflection of the active fleet as sailed in the clubs.

Interesting thread.

Personal perspective, owning a 9 (most of my racing in that) and having used borrowed 7 rigs a fair bit, and being on the heavier end of the spectrum:

I can be competitive in the 9 rig (speed-wise, my tactics and boat handling aren’t up to being consistent) in winds up to mid-twenties (kts). It’s clearly possible to perform well in winds above that (Matt, Greg, etc) but it requires a level of skill (and practice) I don’t have. In a chop, the taller mast of the 9 doesn’t seem to do many favours, as the boat moves around more and the top part of the sail doesn’t seem to help as much as it does on smoother waters. I’m sure, again, that with practice and fitness you can work it through but it’s a rig that is hard to make it work in the stronger stuff. Given a choice I’d move down to a 7 at around 18kts sustained or gusts of over 22kts, but the 9 is probably better for my technique & improving my skills. The 7 feels bogged down under 12-14kts given my current 102kg (a bit too much lock-down snacking...).

In the lighter stuff & on inland puddles I can be quite quick, but it’s really critical where you put your weight fore-aft; as my weight has changed I’ve seen the difference get a lot more dramatic around 94-95kg – if you’re heavier than this it’s hard getting the boat going in light airs (<5kts) and it slows up quicker than those around you (I’m thinking it’s much harder to keep the tail from digging). Once you’re over 100kg, this becomes pronounced. That said, as soon as you’re out of the drifting conditions and sailing in 4-8kts the boat picks up again and you can make it work providing you keep forwards.

Can someone explain this statement? I thought that as a sphere as the maximum volume for minimum surface area that a rounded hull like the laser would gain surface area at a lower rate than a chined hull.

You are right, a sphere has the minimum surface area relative to volume. 
However we are considering the change in surface area between a 35kg and a 105kg person. The low chine and vertical sides mean that a 35kg sailor is already at max waterline beam and adding weight then gives a lower increase of wetted surface.
At the recent Eastbourne Nationals with over 100 sailors weights ranged from about 44kg-105kg. We have had 35kg sailors enjoying the RS Aero 5 up to about 15kn.
 
From the original RS Aero datasheet;
'The early prototypes had a higher chine, however through development, the chine has dropped to just below the water line amidships. This has proved to have several advantages: 
• A 35kg sailor gains the benefit of approximately the same waterline beam and hence the same hull form stability as a heavier sailor 
• The waterline beam and wetted surface does not change significantly with an increase in helm weight'

I would have to disagree sorry, based on my enjoyment of sailing both the RS Aero 7 and RS Aero 9 similar amounts over the last 6 years.
It adds a lot of interest, keeps me in the right power range when I choose to be and sometimes I don't chose to be. The rigs are so similar and everything else remains unchanged, so the simplicity of the RS Aero does not suffer and it all fits nicely in the bags under the cover for storage and transport. With alternating two rigs the sails then last much longer too, especially the RS Aero 9 if (unlike me) you mainly use it in lighter winds. You just have options and most keen RS Aero owners choose to exercise that flexibility with a 2nd rig to achieve more good sailing days at each end of the spectrum.
I understand RS are offering a 25% discount off a 2nd rig with new RS Aeros at the Southampton boat show starting tomorrow....


Fair enough ... and I hope they got their money back on the stand
