The review from Gerrark mentions a lot of cards that were menaces against ice, but have since rotated out of standard. I'm glad to tell you that three years later, we have a brand new assortment of cards trivializing ice!
The three new big non-icebreaker ice answers are Botulus, Boomerang and Endurance, (Hey, one in each faction!) and this makes all of those very sad as well. In particular, since the boat often relies on banking a large number of counters to threaten a remote, this can give you a late-game scoring window you'd otherwise never have. The boat looks primed to be a serious metagame threat, so having a card which shuts it off for a critical turn can be extremely powerful. In addition, since the addition of powerful upgrade hate like Light the Fire and Pinhole Threading it pays to have a way for glacier to score which isn't dependent on such cards.
The caveat is the same that's always been true for all the lockdowns: you want to use them the turn you're planning to score and it therefore takes up a critical click on the turn you need it most, so unless you're trying to score out a 4/2, you're probably not using the best tool for the job. Scoring a 3/2 is probably easier through a fast-advance plan, and a 5/3 requires additional clicks to score. Thankfully, since you're playing this in HB, you've got the best support card possible: Seamless Launch, which enables you to install-advance a 5/3 and still score it next turn.
The deck that this most neatly slots into - defensive upgrades, HB, Seamless Launch - is the turbo glaciers we've seen out of Precision Design. PD has to make very few changes from the most popular decklists to slot this, and this card could end up being a premium non-tech tech card in the coming metagame.
