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 hinge mounted, self closing MastGate (stainless steel 316).  Once installed, it is a hands free, self closing operation, and no tools required for use.

We also have Externally mounted stainless MastGates for luff channels that can't fit an Internal MastGate.

Last year we added 3D printing to build custom plastic inserts for round and complex luff geometries to bridge the sail feed gap in your mast.

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.

 Once you pop in a sliding 3D plastic insert into your feed slot, it never needs to be removed.  
To add or remove sail slugs, pinch one end of insert together (reduces its diameter) while pushing to slide it in direction of pinch.  To close, just slide insert back into position.

Add Cleat Shield Protectors.  Sailing & Safety:

Prevents unintentional snags during a jibe.

Snagging Fishing and anchor lines.

Hooking onto clothing or skin.
Prevent cleat horn breakage when stepping aboard.

Holds dock line from slipping off.

If you can not afford to spend $300 for Antal's 280 roller , please consider us!

Order our LOW COST, small boat solution to this age old snagging problem.

Place our expandable Cleat Shields around your cleat horns and your lines will sweep up & over without a hangup.

An elastic cord pulls the shield halves together for a firm attachment over a dock line and around the cleat horn.  This aids in securing your dock line from slipping off.  The pull string aids in removing and tethers to your finger to prevent loss.  Hang them away for storage.

Potter-15 user states he no longer snags the main sheet on stern cleats and a ComPac 16 sailor states he only needed one cleat shield to prevent hangups.  I use them on all 7 of my Potter 19 cleats because of the utility and they are pleasing to look at.  The bow anchor cleat is a much larger size version.


​​​​​How often are you caught off guard to reef or change sail ?

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.
