sorry but what singlehander for lowcost speed?

I'm looking to get back into dinghy sailing after a bit of a sabbatical for a few years where I've focused on solo big(ger) boat sailing.
Through my yoof I had or sailed on lasers (1&2), larks, ents and microtonners before heading off for west coast Scotland remote rocky bits and away from racing.

I'm 192cm /6'4"ish, 85kg naked and quite fit.

My requirements are for a boat <£1,500 but pref <£1k thats good for a blast, easy to right without rescue boat (which the Lark was anything but) and light enough to get up the beach without assistance.

As a wild card requirement something big enough to strap a 30l dry bag and hip flask of whisky too for occasional weekend bivvy trips is a bonus. I'm versed in fair weather, traveling light bikepacking on the mountain bike so you don't need to suggest a wayfarer with boom tent, I have a cruising yacht for bigger trips.

I'm thinking something along the lines of a Sprint 15 or Contender, what else should I be looking at?

Sounds like you want an old beach cat. Sprint 15 might do. You would want a good big wheel trolley single handed on a beach - they're not cheap.

I'd agree with the 600, although i'm wayyy too small for mine, its been great for blasting and such a fun boat to learn helming from the wire in over the summer! Also generally robust, light and quick to rig and get on the water in minutes!

You won't get much Contender for £1500
What about a cheap old L2/Fun with harness and long stick?

If it really blows up you can get home old skool with just the jib.

It's not light but an older Finn would otherwise fit the bill.  I've camped and cruised in mine many times, you can sleep aboard or take a tent.  I use an OK sail if it gets too windy.  It's a heavy boat but I've never not been able to get it up a beach or slipway by myself, but help is appreciated!
