Vasu, I'm reading a bit between the lines here, so correct me if I'm wrong.
It sounds to me like you have a fair amount of money to play, but normally don't have the time. With the virus you have the time now.
I agree with JohnBPrice, since your opportunity is right now.
Go watch some good youtube videos and get a beginners idea of what to do.
It's an excellent book that I used to teach myself to sail my first dinghy two decades ago. It's not as daunting as it seems, as only the first 1/4 of the book will be necessary to helping you get on the water on a dinghy. The rest of the book is very useful, but will deal with larger boat skills.
Buy a local small dinghy and some decent safety gear. Something under 17' feet, even just a laser or something simple. I would suggest a decent wetsuit and PFD. You'll be amazed how tired you'll get after a few times of trying crazy things and flipping your boat. But you'll have fun, and learn incredibly fast.
Go enjoy your time now, and learn. I've read and heard multiple times over the years that "An hour spent learning on a dinghy is worth 8 hours on a large keelboat.
" and I believe it's true, especially with learning the basics.
Then, when the schools open up again, take the courses that have been recommended here. You'll have a big head start since you'll have dinghy sailing under your belt, and you'll actually have pursued your dream now, while you're able to.
