I would say it is going to be down to the fact that the L2K et all are just lighter and as such will plane a little earlier and a little easier than the Vago which is comparitively heavy.

I notice this in our club Vision. When it is windy the boats goes quite well on all points of sail. When it is marginal you really have to work hard to get the thing to accelerate and get up on the plane. Once it is going it is fine.

Looks like it's definitely the marginal planing conditions
that are the problem. Today nobody was planing and we were
quick downwind again. Crew forward, me on the thwart and
centerboard up.

RS400, no trapeze, would easily carry that weight: inland or on open water.

Anybody recommend something akin to a double handed

explains why you are a bit slower downhill but quick upwind (i'm guessing in a bit of breeze) I wouldnt go changing class just yet though as most dinghies of this type (Asymmeteric and single wire) have weight ranges the same (such as th r500)

For club racing? Iso or 4000.

Fair bit more power than the Vago, neither is actually heavier- Iso hull weight (wingless) varies about 95-105kg (wings add a fair bit of weight- very crude weight equlaisation), 4000 is I believe of similar weight.

They're of similar speed- which makes the Iso the "Phantom" as it has the higher PN, especially if you get the newer Hyde sails.

My crew (wife) and I have had a chat. We're going to cut
back on the iced buns at lunch time.

It's a shame. I'll miss them.

I might also try and tighten our centerboard which I
noticed tonight is exceptionally lose.

Had a rubbish race tonight. Not only were we slow downwind
again but we were slow upwind too.

"Most" Laser 2000's that race have raced in or against people that do Open Meetings of 25-40 boats. "Most" Laser 2000's are experts at soaking low: they get lots of practise and there are masters at it in the fleet.

If the wind is less than planing speeds, I wouldn't try and get anywhere near a Laser 2000 angle (my experience: RS400, Vareo and Laser 2000).

The Vago is designed to be more of a skiff shape. This would mean that higher and faster is the way to go. Whether the weight of the Vago + the weight of you as the crew enable this, I don't know...

I must admit I'm not exactly proactive when it comes to
waves. Although we're in Portland Harbour which isn't
exactly famous for it's lumpiness I will try and give that
a go.
