Boats will collide with Marker armorstands, invulnerable, invisible, no matter what will always collide.
Boats also collide with paintings, itemframes, arrows, etc. Non-living (non-mob) entities.
What should happen:
Should only collide with "living" entities, boats, nonmarker armorstands, players, and such.
Not with marker armorstands, arrows, items, itemframes, paintings.

You have to make sure that the Marker ArmorStand is not in the ground
Boats are probably only supposed to collide with all mobs and ArmorStands with Marker:0b

Please link to this comment in the description
The following is based on decompiled version of Minecraft 1.9 using MCP 9.24 beta. All method and class names are the names used in the decompiled version.
The reason why this happens is because the method net.minecraft.entity.item.EntityBoat.getCollisionBox(Entity) uses always the collision box of the passed entity, whereas for example the method net.minecraft.entity.item.EntityMinecart.getCollisionBox(Entity) (Minecart) only uses the collision box if the entity can be pushed.
/**
* Returns a boundingBox used to collide the entity with other entities and blocks. This enables the entity to be
* pushable on contact, like boats or minecarts.
*/
public AxisAlignedBB getCollisionBox(Entity entityIn)
{
// Replaced this
//return entityIn.getEntityBoundingBox();
return entityIn.canBePushed() ? entityIn.getEntityBoundingBox() : null;

I can't seem to reproduce this in 16w05b.
