Boat Terminology Questions

I'm looking for the name of the part on recreational boats which looks like a foil shaped roll bar and may function as a ski/towing tower, bikini cover/frame or radar mounting location.

Example:

 

I call it a radar arch.

 

Sometimes referred to In Aussy as a "TARGA bar"

 

Arch is probably the most common. Sometimes refered to a Bimini arch or cockpit arch or antenna arch or radar arch or ski tow arch.......

 

Thank you, I've been looking for examples and wanted the proper search phrase.

Using "boat arch" I picked up this image.

I'll be using additional images to help influence some for fun design sketches I'm doing in my spare time.

Looks like some become spare parts for others.

The "arch" I'm considering would be removable, and only as high as needed for a seated position. Not sure if I'll be able to find a comparable.

 

Also take a look at wakeboard towers for trendy designs.

 

It's called whatever the marketing team things will sell best. It's a unless styling contrivance, but this phrase hasn't quite the appeal as Man Arc or whatever the latest one is called.

 

Alright, I have another term "sneeze".

Is that like porpoising? As in rocking from bow to stern?

the device on this sailboat I would suspect is called a boom rest, but it is a similar structure. Lots of classic wooden sailboats have them.

 

"Boom gallows" is the name I've heard for a transverse frame on a sailboat which is intended to support the boom when the sail is not hoisted. No knowledge of the origins of the name.

 

RADAR ARCHS are not made to pull from in anyway shape or form !!!

Take a look at wake boarding boats !! they have dedicated high up tows made specially for the job !!

 

I think Hunter Yachts (and others) would argue this isn't correct, with huge mainsail sheet (and other) loads, absorbed by the arch.

A boom gallows or boom crotch are common terms (other image), depending on how old you are and what part of the world you live. I don't think this was what the OP was referring to in his question.

ok ok ok !!!

i should have said the ordinary arch is never made to pull anything just carry some weight thats all !! BUT theres no reason at all they cant be made special purpose built !!

 

Interesting features, thanks for the vocabulary tour.
