The Laser isn't a surf-board, so if you're carrying it - you'll need at least another person on the other side. I use a dolly to walk it down to the beach myself and pulling it off that is an easy job for a 30yr old (me). Rigging it is a one person job too.
As for transport, I simply use the club's Laser, so I cannot speak from experience. That said, she packs up pretty well and is relatively small & light (compared to other dinghys), so with a trailer it would be quite simple. Apparently it was designed to be possible to stick on one's roof racks as well. Given the light weight and small size, I reckon (with another person to help you get it off & on) this would work well too.
I'm a lake-sailor at the moment, so cannot speak about how well she sails in the ocean. That said, everyone of the promo videos I've seen of the Laser is with a guy sailing it in/through the surf. That said, they look far fitter than me, so your mileage on that might vary.
