Having spent 14 years exploring the west, I've been giving thought to where else. The only vehicle i ever bought new was a 1980 Datsun (before they rebranded as Nissan) 210 hatchback. With a 5-speed transmission it got 30mpg pretty consistently. The last time i saw it my daughter was driving off in it. Thus, shopping for a boat, i'm more likely to go with used, but this Polar Explorer -- still in the outfitting stage -- holds a lot of appeal.
With enclosed helicopter hangar and duel/fuel (methanol) capability.
If you stayed away from the piers, you could probably even avoid the parking fees.
Smaller ones.
