Trogear Bowsprit Through Hull Installation Manual 

Congratulations on your purchase of the Trogear Bowsprit 

which can be installed on most sailboats. The through 

hull installation is not a complicated process, but it does require careful measurements. Please read the 

instructions 

thoroughly

 

firstand if in doubt contact us or your boat rigger with any questions. 

Keep in mind that these instructions present the basic process. As each boat is designed differently, your boat may 

require specific installation modifications. Again, please consult your rigger if in any doubt, and you may decide that it is 

best to have your rigger install the Bowsprit for you.

NOTE:

 

If you are not able to install our bowsprit using this method, our side mounts or deck mounting solution might be 

right for your yacht. 

Custom options are also possible and we can work with you to devise a suitable method for your 

yacht. 

 See our website or contact us for details.
