I’m going to run power from my house to my pier. It will be a nearly 300 foot run of #10 wire. Should I make it one continuous run to avoid places where possible corrosion would set in, or should I have a few junction points along the way to make repair easier in case it should get accidentally cut in the future? Any thoughts?

one pc.
if it gets cut somewhere THATS where ya add a Jbox..chances of damage near an easy spot to fix are naturally nil..

Don't forget, a moderately skilled carpenter could incorporate a j box into a panel or cabinet or something, just in case you don't want it looking out of place.

One run, but leave some slack.
Note that on a long run you should upgrade the size of the wire, to reduce voltage drop.
how much amps are you going to use 10 amps starting w@ 120 v you end up at 112.8 volts.
20amps starting @ 120v you end up at 104.5v
20 amps starting @ 240v you get 225.5v
on voltage drop calulator at this url http://www.csgnetwork.com/voltagedropcalc.html
300ft one way?
You are going to need a fatter wire.

Of course its ONE WAY.! You dont think he's gonna run it back again ,do you?
ROAR!!!!!
DAM I wish I'da caught that...hahahahahaha

Isn't that how you make alternating current? One flow out and one flow back? ;-)
You will be running PVC conduit and pulling individual conductors, won't you?
It's one way. The biggest draw this sees is an ice eater that draws about 5 amps at startup. Before the existing line developed a fault to ground, the #10 wire that was in place resulted in a 3 volt drop at 120v. I'd start with 122v, then drop to 119v with the ice eater running. And yes, I plan to put individual stranded conductors in 1" conduit. I may need to reconsider that conduit size if I go with the #8 wire the voltage drop calculator recommends. Ouch! Harder to pull and more money...... must be better. :)
