So, this took a fair amount of listening to the song, but I used the English translation and re-worded it to run with the tempo of the Japanese lyrics.
The original translation is in normal text, and my adaption is in bold.
It's all right! Let's step forward. Always carry the Sun in our heart
and hand in hand the power will pass through. Let's grasp our wish.
It’s all right, let’s go and move onwards now. We’ll carry the sun’s power in our hearts. When we are together we’ll be stronger, so let’s run away towards our dreams!
Let's ride the big wave with united efforts.
Let's hurry in the direction of the excitement: it's the signal of the beginning.
We’ll ride the waves with all our strength, each one of us will have his part. Let’s run off towards excitement now, and find a new beginning!
Now is the time of the departure. When we weigh the anchor,
Strut along the seven-color wind, and let's jump out to the adventurous sea.
Let’s go and shove off away from home, hurry and pull up the anchor! Let’s fly along the winds of the world, and off to adventure!
It's the voyage with lots of injuries, but the important thing is there.
If there are pinches, anytime, anywhere, I'll protect you.
We may find ourselves in a lot of trouble, but we always will still have each other, too. If you need help, we’ll always be there; we will be there to protect you!
It's all right! Let's proceed forward. Always carry the Sun in our heart.
When the storm comes, let's put our shoulders together and look forward to the hope (light) after that.
If the pieces of our dream are gathered, it'll become a navigation map that points to the future (tomorrow).
So let's get together under one flag and grasp our wish.
We're one, One Piece.
It’s all right, let’s go and move onwards now. We’ll carry the sun’s power in our hearts. There will be bad times where there’s no escape, but we’ll stick together, and look forward with hope!
If we come together and chase our dreams, our destinies will point us towards the sky! So let’s join under the symbol of our hopes and dreams, and find a way to achieve them!
We’re united, let’s find the One Piece!
If you read along with it, you should be able to sing the English lyrics fairly well without missing a beat. Or, at least, I can. But still, I'm proud of it.
