The recommended size of crochet hook for working with yarn that is 5mm thick is typically a 5mm crochet hook.
The recommended yarn weight for a size 25 crochet hook is typically super bulky or jumbo weight yarn.
For this project, you should use a size 6 yarn crochet hook.
Is there any particular reason that you want to carry the yarn behind your crochet work? Why not crochet the carried yarn into the top of the previous row? That way you wouldn't have to cut the yarn. Check out the attached videos to see how it can be done. (although one is hard to see really easily, as the green yarn is being carried on the green stitches below)
I suggest not crocheting swimwear because it could tear and get soggy
To prevent yarn splitting while crocheting, use a crochet hook that matches the yarn weight, avoid using yarns with loose fibers, and crochet with a consistent tension to keep the yarn intact.
To do a double crochet do a yarn over, insert your hook into the next stitch, do a yarn over, pull the yarn through the stitch, yarn over, pull through 2 loops on the hook, yarn over, pull through the last two loops on the hook.
No, they are not. double crochet: Yarn over, insert hook into specified stitch, yarn over, pull through stitch, yarn over, pull through 2 loops on hook, yarn over, pull through remaining 2 loops. half double crochet: Yarn over, insert hook into specified stitch or space, yarn over, pull through stitch (3 loops on hook), yarn over, pull through all 3 loops on hook.
You can visit a local yarn shop for inspiration and ideas.
