Merry Christmas: Bring MastGate  Aboard  for Safer Sailing...

Contact us for custom quotes to built to your needs.

We can also provide screw on adapter to add a nylon flex rod to change location of handle in mast.

On my West Wright Potter 19 I use 4" rod QRTS under sliding boom to limit boom drop during reefing and to lock boom above my head while reefed for more cockpit head room.  Handy to setting up a tall boom tent.


Our most useful and elegant design solution is our Internally hinged mounted, self closing MastGate (stainless steel 316).  Once installed, it is a hands free, self closing operation, and no tools required for use.

We have Externally mounted gates for mast profiles that can't fit the above Internal MastGate.  Our selections of a Fixed or Removable MastGate is a great solution to bridging the sail feed gap.

I will help you select the best MastGate solution depending on your mast's cross section profile, length & width of feed slot, type of sail slugs, and how often you remove your sail.

​We have introduced modern 3D modeling tools to build gates for round & complex luff channel geometries.

Sail slot handicap disability eliminated.

Some of our inserts and sleeves are pop-in solutions (*) and some require attachment.  

We currently modeled MastGates for:

*Catalina 18, 22, 380 *Capry 25; *Hunter 225; *SageCat 15, & Sage 17; J-109; Tayana 37; Tartan Thomas; Lindenberg and Dwyer  *DM3 , *DM368 , *DM375; Z Spar 701 ; SparCraft FM385 ; Beneteau 36.7 .

10 year Estimated warranty life span.

Please confirm your sail Slot lengths, Width, and Sail Slug part number.


​Gates are built using either carbon fiber, poly or nylon based plastics to build you the best insert or sleeve to bridge the sail feed gap in your mast.

I will help you with the best MastGate solution depending on:

  1. Mast's cross section profile.

  2. Feed slot length & width.

  3. Part number on sail slugs.

  4. How often you remove sail for storage.

​​​​​Are you a Single or Short-Handed Sailor?
How often will you change or remove sail before a weather change?

Balboa-26 sailor says:

"My MastGate fits and works perfectly. We reefed and un-reefed several times in high wind while underway. Reefing has become a sail trimming option as opposed to something to be done ahead of time. Thank you!"

NorthSails ​Sailmaker says:
"I like your product very much.  I am a sailmaker for over 30 years and I always joked that most mast companies never figured out the sail / mast connection. "

Your product is slickest application out there. 
....  will now direct clients to your site as a solution.

Chris K (US Yacht 25 “Chinook”)

The Internal MastGate ... ” I raised,  lowered and reefed several times with no problems.  It was the first time I’ve ever been able to actually go to the second reef, and it was easy at that.  Great product.
Thanks again!"

John C (Beneteau 36.7)  I used to worry about sending some one to the mast to baby sit the slugs.

Now I no longer think about lowering or raising sail since installing my carbon fiber MastGate insert.

QuickRelease TrackStop (QRTS) has replaced the round knob types.

Sailors with wet, cold or arthritic hands curse those small metal knob stops and say good bye when they bounce overboard.

Welcome to our easily to use dual cam action locking & release system.  

Places you will want to use a QRTS:

1.   block the opening of their feed slot, because it is only a few inches above a fixed boom.

2.  place one under a sliding boom to limit drop during reefing.

3.  increase head room under boom by sliding it up mast while at rest.  Release when ready to sail.

     (note: to hold back end of boom up, use topping lift or halyard.)

Hard to believe, but Weight is similar to the round knob types, because our handle is made of a tough composite resin from Germany.

Cleat Safety Shields prevent unintentional snags of:
Main sheets during a jibe

Fishing and anchor lines

Clothing or skin.
Protect cleat horns when stepping aboard.

We have the solution to this snagging problem.  When you place our expandable Cleat Safty Shields around your port and starboard  cleat horns.  Now lines will sweep up & over without a hangup.  Don't let a hangup cost you precious time during a race. 

A pull string aids in removing the shields and tethers to your finger to prevent loss till you hang them away for storage.
The two shield halfs are connected with an elastic cord to fasten sheilds around the clete.
This safty system aids in securing your dock line from slipping off when you place the shields over it.
Order as a kit or pre-assembled. Made in USA. 

Potter-15 user stated he no longer snags the main sheet on the stern cleats.
