I would take the skyliner 100 times out of 100.
The skyliner station is a 3 minute walk from BCV, then about a 17 minute ride with a change of cabs in the middle. And the DHS skyliner station is right near the park entrance.
The walk from BCV to HS is more than a mile. Yes you can probably get there faster than Skyliner, especially if power walking. But IMO much better to ride in comfort at the start of what will already be strenuous day.
Boat is neither convenient nor fast. Only take that if you're more interested in the scenic journey with no concern over how long it takes to get there.
