Would medieval armour help in an age-of-sail boarding action?

Would troops equipped with medieval armour and shields have an advantage in an age-of-sail boarding action?

Only in limited circumstances; the equipment could help inside the ship but would hinder movement and offer little protection from musket fire during the approach.

The answer separates the exposed crossing from the fight after troops enter the ship. Period armour would not reliably stop musket balls, and large shields would be awkward when climbing through gunports or moving between vessels. Some protective equipment might become useful once fighting shifted into confined decks and passageways. Every addition of armour trades protection for flexibility, a serious cost in shipboard combat.
