Your foreach loop is generating duplicate id attributes (invalid html) and name attributes which have no relationship to your model. Change the partial to an EditorTemplate

/Views/Shared/EditorTemplates/CourseHole.cshtml

and remove the BeginForm, AntiForgeryToken and scripts

@model Golf_Statz.Models.CourseHole
<div class="form-horizontal" id="CreateHole-" + model.CourseHoleId>
    <div class="form-group">
        <div class="col-md-2 col-md-offset-2">
            <p>@Model.Number</p>
        </div>
        <div class="col-md-2">
            @Html.EditorFor(model => model.Par, new { htmlAttributes = new { @class = "form-control" } })
            @Html.ValidationMessageFor(model => model.Par, "", new { @class = "text-danger" })
        </div>
        <div class="col-md-2">
            @Html.EditorFor(model => model.Length, new { htmlAttributes = new { @class = "form-control" } })
            @Html.ValidationMessageFor(model => model.Length, "", new { @class = "text-danger" })
        </div>
        <div class="col-md-2">
            @Html.EditorFor(model => model.Ranking, new { htmlAttributes = new { @class = "form-control" } })
            @Html.ValidationMessageFor(model => model.Ranking, "", new { @class = "text-danger" })
        </div>
    </div>
</div>

and then in the main view

@Html.EditorFor(m => m.Holes)

The EditorFor() method will correctly generate the html for binding to a collection, for example

<input name="Holes[0].Par" ...>
<input name="Holes[1].Par" ...>

You also need to remove the [Bind] attribute since you are excluding property Holes, and you seem to want to bind to all properties anyway.

Side note: You do not generate an input for the hole CourseHoleId or Number properties so these wont post back.

In your case you have two forms! Razor would generate this

<form>
    <form>
    </form>
 </form>

remove @using (Html.BeginForm()) {} from the partial view
