Whooooa man! Reading that is just heartbreaking man!!!
Hope it's ok for me to say this, but one of my good buddies who I fish with often (and a BDer on this board) lost his dad just a few short years ago to the ocean as well and also while he was by his dads side. My buddy (Ryan) was about the same age as you Cody, and very very tight with his pops. His dad was an incredible man like yours.
The point of me saying this Cody, is that you will never forget, but over time you will slowly begin to heal. It took Ryan a while to face the ocean again, but he does so in full force now again as I think he knows that is what his dad would want, and Im sure yours would too.
Take care buddy, and dont feel afraid ever to express your feelings when your down to your true buddies cause they are the ones who will help lift you back up and get through this.
Your dad sounds like an incredible man, and just seeing what you wrote was amazing for something that happened so recently. Keep making him proud as Im sure you always did and know he is always right there with ya!
My thoughts and prayers go out to your family!
PS: Ryan, If your not cool with this please let me know and I will delete.
