Water based varnish, anyone?

So, I'm approaching the staining and varnishing segment of this restoration project, and have some curiosities. This very well may be a stupid question, but I've heard a lot of great things about these new water based varnishes/spar urethane's, etc. So my question is two-fold. 1. Would any of these water based products be sensible to use instead of traditional oil based stuff? (on the inside or outsides of the boat or both) And 2. If that should be avoided, what are your favorite brands of oil based varnish to use on the entire boat? (and I'm sure I'll get 20 opinions on this one, but I'm all ears)

And as a Bonus: 3. Anyone have a strong opinion against using regular yellow can minwax penetrating stain instead of the Interlux filler stain? (I'm a cabinet guy so I'm very familiar with minwax stain, but haven't experimented at all with the filler type stains)

Stay with the traditional oil based boat products. Water based paints and varnishes are not breathable, trap moisture, don’t sand well, and generally look like a plastic finish. Important to use the Interlux filler stain to fill the 80 grit sanded wood. Always apply two coats of sealer over the fully dried stain and a full coat of varnish before your first sand then build from there. I use Interlux Chris Craft filler stain, Interlux sealer, and Pettit Captains varnish. Have Fun!

NO THANK YOU. Have recently tried TB Halycon and Pettit Sea Gold. Not pleased with either. The former comes out of the container pure white and despite being described as clear and glossy it's neither. Sea Gold is way better but still a matt finish, not bad as a base to build up come coats but I wouldn't use it outside of the boat. I finish everything with Captains which is my go to varnish (tried most of them).

Bonus: I use Minwax Sedona red inside the boat with a base of sanding sealer and have been very pleased with color and finish consistency. Outside I use Interlux Chris Craft red filler stain mostly for correct CC color and "look" of the finish.
