What to wear on a Kenai Fjords cruise

There is a particular kind of disappointment that this trip produces, and it is worth naming because it is entirely preventable. People board at Seward, find a seat in the warm cabin, go outside when the captain calls something over the speaker, last about four minutes at the rail, and come back in. They do that a few times. Then the boat reaches the ice, and the one moment they came for — standing in front of a wall of glacier, waiting for it to make a noise — is a moment they can only manage briefly, because they are wearing a sweatshirt.

The reason has nothing to do with how cold Alaska is in the abstract and everything to do with the fact that you are on a fast boat. The listings for $297 and $265 both describe a stable, high-speed catamaran, which is exactly what you want for covering distance in a day — and a boat covering distance generates wind across its deck regardless of what the weather is doing. Add spray coming off the water and you have the two things that make a warm jumper useless: moving air and moisture. A thin windproof shell over an ordinary fleece beats a thick coat with nothing on the outside, every time, and it packs smaller.

The second thing people underestimate is how much of the day is spent standing still. A six-hour sailing is not six hours of walking about. The good parts are the parts where the engines come down and everyone goes to the rail: the rookeries on the Alaska Maritime National Wildlife Refuge, a raft of otters, a whale the naturalist has spotted, and then the long stop at the tidewater glacier. Standing still outside is the hardest thing to dress for, and it is the thing the whole fare is for.

Third, this is an in-and-out day rather than a one-temperature day. You will go from the cabin to the deck and back repeatedly — when lunch comes round, when the captain calls something, when your hands have had enough. Layers exist for exactly this. Two or three thin things you can add and shed beat one warm thing you cannot, because the warm thing is either on or in your way.

And a small practical note rather than a medical one, because it is the question people write in about: if open water is new to you, the usual sensible things apply — eat something light rather than nothing, take a spot outside in the fresh air with a view of the horizon rather than a seat below deck, and get yourself sorted before the boat leaves the harbour rather than after. One listing on this site, $260 from Whittier, goes as far as publishing a no-seasickness guarantee in its own highlights. Beyond the practical, anything to do with your own health is a question for your own doctor and not for a travel page.

There are two different kinds of day on this site, and they pack differently.

A cruise means a boat with a cabin, and you pack for the deck. $265 is six hours from Seward with a captain guide, binoculars aboard, a deli lunch and coffee, tea and water, at 4.9 from 851 reviews. $267 is the six-hour run with a wildlife guide aboard and a hot lunch. $271 is seven hours and lets the captain pick the route on the day. $297 is the seven-and-a-half-hour version with two tidewater glacier stops. On all of them you have somewhere warm to retreat to, which means you can carry less and rely on a good outer layer rather than on bulk. It also means that what you wear decides how much of the day you actually spend outside, which is the only thing that separates a good sailing from an expensive one.

A kayak day means you are on the water, not above it. $406 is a twelve-hour day from Girdwood that paddles around icebergs to the face of Spencer Glacier, with two Alaska Railroad trains built into the journey and a catered lunch. The listing supplies splash tops, spray skirts and life vests, so the outer shell is handled — what is not handled is what you have on underneath, and cotton is the wrong answer on a kayak in a way it merely is not ideal on a deck. Synthetic or wool layers, and a change of clothes waiting for the end of the day.

A road day packs like a road day. $200 is a six-hour shuttle run with several stops, listed with WiFi in the vehicle and all entrance fees included, and $389 combines the Portage Glacier boat, the Alaska Wildlife Conservation Centre and the Alyeska aerial tram in eight hours. You are in and out of a vehicle rather than standing on a fast deck for hours, so the same layers do the job with less demand on them — although the tram at 2,300 feet is its own kind of exposed.

The verdict. For the sailings out of Seward and Valdez, the shell is the item that matters and everything else is detail: a windproof hooded jacket over a fleece, and you can stay outside for the whole glacier stop. For the kayak day, the shell is supplied and the base layer is the item that matters. For the road days, dress normally and keep a warm layer in the bag. The packing list above covers all three — only the emphasis moves.

1. Dressing for the harbour instead of the deck. The harbour is sheltered and the boat is not. A high-speed catamaran generates wind across its deck on the calmest day of the season.
2. A thick jumper and no shell. Wind goes through wool and spray sits in it. A thin windproof layer over a fleece is warmer than either on its own, and it packs into a bag.
3. A hat that blows off, or none. Ears are the first thing to give up at the rail. A close-fitting hat under a hood solves the whole problem for almost no weight.
4. Open shoes on a wet deck. Spray and other people’s boots make decks wet. Closed shoes with grip mean you move around the boat freely instead of picking your way.
5. Nothing for the long stop. The glacier stop is where you stand still longest, and standing still is what gloves and a hood are for. It is also the part you came for.
