g-dog is right,
As a learner in the initial stages of getting your sh#t down, launch and land on the beach unhooked. Once you get more confident, sure, hook in but again, as I do, keep a hand on the quick release, especially on a self launch. Unhook for a couple of reasons.
1. Its easier to let go should you get lofted
2. The wind along the beach suffers turbulence and stray gusts more than out on the water, so the lovely steady wind on the water may have a surprise for you and your inexperienced hands on the bar when on the beach.
3. There are others on the beach that need you to take care of them and yourself, you cannot take care of others skidding down the beach on your head with an out of control kite after it luffed, rolled over and shot through the power near landing.
Ask the big guy today who went skidding down the beach and almost took out me, my student and my 6 month pregnant partner

. Anyway, he did the right thing by chucking the safety and everything so that he was going to be OK.

I eventually caught up to the kite and stopped its speedy trip down into windsurfer land further downwind. Reason, only one lesson and a wrongly rigged safety leash which didn't depower the kite.
Launch depowered a bit on the trim strap (so that you still have steering) and just walk into the water, then hook in. Everyones then happy.
Oh and g-dog, dont be flying your 12m Trio in 20 knots of wind with a buggered wrist.

Have fun and be safe
