Plundered Hearts (1987), an interactive romance novel by Amy Briggs.
As described on the box:
In the 17th century, the seas are as wild as the untamed heart of a young woman. But when you set out on the schooner Lafond Deux, bound for the West Indies, your thoughts are only of your ailing father who awaits your care. Little do you know that your innocent journey will soon turn to dangerous adventure.
You barely survive an encounter with pirates, whose plans for you include a fate worse than death. The explosives, the rocky reefs, the vicious crocodile - all these are obstacles which you must overcome with cunning and agility. True, it's not easy; but at least you can control your fate. What you cannot control is much more dangerous: your passion for Nicholas Jarmison, the handsome pirate captain.
Tall and lean, with azure eyes that penetrate deep into your soul, he makes your blood quicken despite his unsavory past. When you're in his arms, swirling around the dance floor or secluded in the flowered depths of the gazebo, you are apt to forget your mission.
But don't dally too long with Nick. For your father is waiting, and on his rescue lies the fate of more than one man. Prepare for adventure on the high seas, lass. You'll need every bit of pluck you can muster.
