You have basically two options:
Use nested LinearLayouts:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/boat_1"/>
<EditText
android:id="@+id/entry"
android:hint="@string/IRC"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@android:drawable/editbox_background"/>
</LinearLayout>
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/boat_2"/>
<EditText
android:id="@+id/entry"
android:hint="@string/IRC"
android:minWidth="100dip"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@android:drawable/editbox_background"/>
</LinearLayout>
<Button android:id="@+id/close"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="@string/title_close" />
Notice that I'm using android:orientation="horizontal" for those nested layouts.
Or you can use another content manager, like RelativeLayout. The advantage of this, is that you can avoid nesting, thus your layout will be easier to read/maintain/inflate. This is a brief example:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView
android:id="@+id/text_view_boat1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/boat_1"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"/>
<EditText
android:id="@+id/entry"
android:hint="@string/IRC"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@android:drawable/editbox_background"
android:toRightOf="@+id/text_view_boat1"
android:layout_alignParentTop="true"/>
<TextView
android:id="@+id/text_view_boat2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/boat_2"
android:layout_alignParentLeft="true"
android:layout_below="@id/text_view_boat1"/>
<EditText
android:id="@+id/entry2"
android:hint="@string/IRC"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@android:drawable/editbox_background"
android:toRightOf="@+id/text_view_boat2"
android:layout_below="@id/entry"/>
</RelativeLayout>
