TheHallow has taken on the wonderful job of finishing this story for me, in her own brilliant way of course. Go read her story for the finished copy!

My ending to the story is as follows, and will most likely deviate from whatever TheHallow has planned, but just in case I should warn you:

SPOILERS BELOW.

Ok, if I suddenly get the desire to finish this story then I will, but I'm just going to summarize what I had in mind for it just so you're not left completely hanging, ok?

Some important backstory: Donna and Jim have a moment of feelings, but not quite anything weirdly out of character lovey dovey, Jim tells wren about BEN. that is all now back to the story:

So their ship gets boarded by pirates one day because Jim isn't paying attention (cue guilt trope here)

and it turns out that it was Yono who was collaborating to bring them here, and that Wentworth used to be a pirate with whatever crew had just boarded and he sort of suspected what Yono was up to and had been trying to stop him the whole time (think Quirrel and Snape)

and the first mate of the pirates comes out and is like "we have word there's a jim hawkins on this ship"

and Jim's a bit confused and scared and also sort of hopeful that it's Silver, so he admits that he is indeed Jim Hawkins

and the first mate takes him to the captain's office, which they have commandeered-

it's going to be silver, right?

Jim thinks it's silver

he wonders what silver wants

he starts to get more excited to see him then scared

they open the door

And it's his father sitting there waiting for him, not silver.

(plot twist i know right)

so now for the super condensed ending:

they pillage the ship and take Jim and Donna aboard (only because she absolutely refuses to be left behind in a very feisty show of bravery)

and they leave the others on board, but without any way to contact the academy and likely not enough food to complete the voyage there

and set sail in the direction they think Treasure Planet still lies.

Jim explains the whole situation to Donna and they have a nice bonding session while y know being locked up always fun (she pulls some more spunky-love=interest-with-a-sensitive-loving-side stuff)

and then they proceed to lie through their teeth, and we jump back and forth between jim's perspective of imminent danger (his father keeps trying to befriend him again and he has to keep suppressing his anger and act like he really wants to join his crew) , Donna's perspective of imminent danger (trying to break free most of the time, and working out strategies for how to get off the boat and fending of creepy lustuous pirates) and Zack's perspective of imminent danger (from aboard the ship).

low and behold we reach our climax where jim's father the captain finally realizes that he has been lied to, donna actually breaks out of the prison and Zack passes out from exhaustion and hunger - everyone is about to die oh no what a catastrophe there's some sword fighting and angry yelling and running - and then out of the blue wren appears in this tiny little boat with weapons and BEN (who has been sending out distress signals for days on end, surely one of them is bound to have been noticed)

and then there's even MORE fighting while they escape on to the boat, donna pushes jim's father overboard, and then they all escape only to sail away for a day or two to be picked up by a rescue ship yay happy ending.

we fast forward about a month and wren is being awarded for bravery, zack is doing okay but hospitalized along with everyone else who was aboard the original ship, donna and jim have this nice little flirtationship going on and she has got a job at the academy (soon she'll be attending it as the first female ever and on "scholarship" alone) and everything is going swell for jim, despite the fact that half his class thinks he's now a pirate.

yay everyone's happy and jim resolved his daddy issues the end.
