A Tartan 28 will be closer to your price range, but still quite a bit above it. You can probably find one for 15k. but it will need some work and investment over time. We love ours and it’s plenty of space for a couple. I’ve had my older son it and it gets a bit cramped with 4 people. We payed a bit more than that for our boat and have doubled it in refit and maintenance over the last 3 years. Be aware that its an expensive hobby and will require signficant ongoing cost.
