I have something like this and it works pretty damn well
Don't skimp on filament. You get what you pay for. I highly recommend eSUN PLA+. Prints a bit hotter than standard PLA, but is significantly less brittle and has better elasticity. imho it gives a better initial surface finish if you're not going to be painting as well. I bought cheap filament for a while, it's not worth it.
PLA is sensitive to moisture. Don't leave your spools out for extended periods of time. Standard PLA may get brittle and crack while attempting to feed if left out. Pick up a plastic tub and some reusable desiccant. If you're not going to be printing for more than a day I'd highly recommend unloading the printer and storing the spools.
The v2 has a buildtak like surface. I've not used it before but I'm going to assume it's similar to other plastic print surfaces and simply requires the occasional wipe of alcohol to keep it clean. DO NOT USE ACETONE.
Once you get the hang of things you'll want to print the bed rewiring parts for the mini. It's definitely an issue that will come up, and is easier to deal with before than later.
There's more to it, but once you get your print material situation sorted then you can move on.

"The E-333 uses a renewable silica gel technology that works without batteries or power."
I think this is the same stuff: http://www.ebay.com/itm/281212393556
u/twinbee you're probably better off buying something like this reusable dehumidifier device instead of disposable desiccant bags: https://www.amazon.com/Improved-Eva-dry-333-Renewable-Dehumidifier/dp/B000H0XFCS

I do videos for on my Hobie 16 when I'm at regattas and for fun. I'm usually camping so at night I have my GoPros charging in my tent. Even with using the anti fog tabs my videos always fogged up. The can look completely dry, but when the electronics of the GoPro warm up any bit of humidity goes right to the lense. The trick I learned is to always store my gear in a dry box with a mini dehumidifier. This was a complete game changer and I intend to modify my dry box so I can pass power into it for charging while all components that are used on the water are kept as dry as possible. The only place I store my GoPro gear is in my dry box now.

Laptop to free up space on the SD cards is a great call, but I would recommend having additional SD cards so you don't have to wait 20 to 30 minutes for a full SD card to download to your laptop if you want to make a quick swap.
For being out on the water I would never trust the jaws or suction cup. For doing video on big boats I use this: https://www.amazon.com/dp/B0062U2M4E/ with some adapters to get it to GoPro mounting system. There are also GoPro handel bar mounts that I would put around various poles on the boat.
For on my H16 I use these adapters that I have permanently riveted to a couple places on my boat. https://www.amazon.com/dp/B005YVTK42/
No matter what kind of attachment I use I also do a safety line with some high strength kite string.
Oh, and the expanded batter packs are a must. They can fill up most of a 64gb card on one charge.
And don't skimp on the quality of your SD cards. GoPros write a lot of data quickly and the cheep ones can't keep up and will ruin your video...or just give up trying.
I keep one of these in my small, 18 cubic inch fireproof safe. Prior to getting one when I would open the safe the paper money would leave a disgusting musty smell inside. Now I only recharge the thing every six months. I live at a 200 foot elevation and can see the Pacific Ocean in SoCal. Lotsa humidity most of the year and now no smells. https://www.amazon.com/Improved-Eva-dry-333-Renewable-Dehumidifier/dp/B000H0XFCS/ref=mp_s_a_1_3?crid=KOBS87SR2DEB&keywords=dehumidifier+for+safe&qid=1680298891&sprefix=dehumidifier+for+safe%2Caps%2C234&sr=8-3
