Very similar boats in a lot of ways, but the Sabre is likely a few bucks more and will feel a lot bigger inside than the Tartan, thanks to the foldaway dining table; it also has a higher
displacement and higher comfort ratio, so likely to feel like a bit more boat all around. I have a Sabre 402 and love it, but Tartans are great boats as well. Pretty similar build quality, maybe a bit more exterior
teak to worry about on the Sabre.
One thing of note is that Sabre has a very active online community, which I've found to be helpful in
learning my boat; if you have any questions about the 362 in particular, folks on that site (it's an io.com forum) will be more than happy to weigh in. Tartan has one (I think) but less so.
