I would weigh out costs and ease of installation of various scenarios. How far is it from your start battery to the thruster location? Your windlass and bow thruster should more properly be wired off of the start battery than a house bank. You may need a larger starting battery than you have but no larger than you will need for the thruster alone. Will it be easier to run new #3 cables(or whatever is the proper size for the amperage of the higher amperage device) and move the windlass controller. Since they are both motors, the load type is the same. The breaker is there to protect the wire, not the motors which have internal protection. Weigh this against installing a new battery and charging cables and an echo charger. I personally like to keep battery banks to a minimum. I like to keep things simple and I like to get the best bang for my buck. I would choose the solution that better satisfies these criteria.
