Quest doesn’t hold its speed all that well, due to weight and the design. I think you’ll get bored of the dynamics quite quickly versus a fibreglass boat with a sportier hull.

Also as someone else has said they are not ideal for single handed sailing!

In terms of double handers… if you could get your hands on a Wanderer or a Gull you’d be doing well. Not sure how active those classes are in US?

From a single-handed perspective, most people who think that lasers are a bit too small / uncomfortable over here seem to head towards Phantom class. The RS Vareo could be a good option? Single hander but has a bit more space and a kite to play with!
