Well in Southeast Alaska there isn't much of a selection of hotels, its also strictly drysuit diving and you would have to be nuts to dive wet. I doubt you could get a tourist off the cruise ship to slip into some real cold waters. Secondly our dive season doesn't work with the cruise ships, we dive in the fall and winter, the ships are in during the summer and are already have their things days booked with whale watching, charter fishing, and spending money on trash. Im not trying to shoot your idea down but from my own experience we are self sufficient divers and already have our own boats and fill stations or are saving up for it. Regulations are tight up hear about what you can and cannot do. Yeah you can go whale watching but you cannot dive with whales, and if you did it could be your last. Also spearfishing wouldn't work out well since that falls under the Fish and Game Sport Charter Fishing and that is expensive to get the licenses and requires real deep diving.
For a water taxi its around 50-300$ round trip and they just drop you off in a bay or on an island. There are dive charters and they charge about 300$-600$ per person and it is guided. Secondly the skill set is above the vacation divers and it isn't a walk in the park like with tropic warm water diving. This idea might service a few people, but its not a money maker and I doubt a hundred people a year will cover overhead and turn a profit.
This is from the State of Alaska when they looked into it:
You have to look at this from our perspective, I don't want some tourist diving my waters. Hell would have to freeze over for me to show an outsider my dive spot and if did freeze over bust out the chain saw were going ice diving.
I agree with the challenges listed above however in SE I think that we have a little different perspective about showing where we dive.
I would love to show you my favorite dive spots. I love my waters and we have some great diving. We have a group out of Seattle that come up and stay in a couple of local's homes and then we all go diving. I don't think that it would work for a charter situation because the demand would not meet the cost break point.
Cost of a boat. Well this is all theory because to the best of my knowledge there is not a operating Dive Charter boat to be rented in Sitka AK the one we had was attached to the shop but you can read my prior post to learn that history, I think that you could find a charter fishing boat that you could hire for the day to take out to some great dive spots. I imagine it would run about $600 for the day boat only. But that is just a guess. I can tell you for you to jump on a charter boat and fish for 4 hours it is going to cost about 200 and it would be a 4 person minimum. That is why I was thinking you may get it for 600.
Now if anyone wants to come to Sitka for some great diving just PM and I would love to show you some great walk in spots But be prepared.
The water will be between 30 and 52. The warmest dive I have done at home was 53 in July on a 78 degree day and those happen about every blue moon.
The sea Lions will be around and the first time a 600 lb sea lion comes to play you will need to take a second to remember to not hold your breath.
Please do not come to Sitka to Dive During March and April as the spawning and the bloom can make visibility near black water and you wont have much fun.
Best diving is October to march but the surface intervals can be rough
If you have a lot of money and want to set up a dive operation. PLEASE come to Sitka. I would love to dive and have access to a quality dive shop. It bites having to send everything out for service, In fact I am having to plan a weekend trip out of town to get my Visuals done on my tanks. Load all the tanks into the back of the truck take the ferry ride to Juneau drop them off and then go shopping with the wife while the shop opens special for me to do my inspections. You can imagine how costly that is going to be the shopping alone is going to be a nightmare, but add 2 nights Hotel (remember our room rates ) food and the ferry tickets for the car two adults, Stink I think by the time I am done it may end up costing about 150 a visual for each of my 8 tanks. I am not sure what I'll do when I need Hydros because that will mean 2 trips out of town one to drop off and one to pick up.
So again come to Sitka and set up a Shop Ill be there the minute you open the door
