I get that a lot, the "everybody says" you need a bigger/more expensive/multihull/monohull/long keel/fin keel boat blues.
As far as I'm concerned, all you really need to do is get a boat and whatever you get will, more or less, work out.
I've also been told that saying this is dangerous, sailing is a serious
business, and this sort of advice is akin to giving people scissors so
they can run the 100-yard dash...
The important thing to keep in mind is any number of people have gone off sailing on all sorts of boats with shockingly small budgets and if they can do it so can you...
It's as simple as that.
