Mantus anchor question

[GBonjour]

Greetings to all: I have a 2007 Gemini and I am away from the boat so I cannot try the template that you can download from Mantus to see if their 45 lb anchor will fit my bow roller. I won't be going to the boat for five weeks and want to purchase and take the anchor with me when I go if it will fit.
Thank you in advance for any help that you can give.
Warmest regards
