Hi Guys,

It's now time to play "What's that thingy" again. I've had these 2 "thingies" on my boat since the beginning of the season and have no clue as to their function. Can you please help me identify these?

Thingy #1: (a whisker pole?)

Attached to the side of my trailer with bungie cord. Measures 8'4" long

Pole diameter of end facing towards us is 1"

Other end of the pole, diameter = 1.5"

Thingy #2: (Main sail preventer? Spinnaker sheet?)

The pipe looks like some kind of mast raising device. Do you have a hole on the front side of your mast? I'm willing to bet the rope and pulleys are part of the raising device as well.

Gin pole and block setup for it.

Agreed, mast raising system when you have the hole in the fwd face of the mast.

The block and tackle probably connect to the end of the gin pole and the anchor locker eye.

I have the mast raising system on my trailer and am very comfortable with it. So this would be some sort of appartus to lower/raise the mast while on the water? Can you briefly explain how that is done please?

Exactly right... it is the mast raising gin pole and block and tackle used with it.

If it gets used, be sure to pretension the halyard a bit as when the load comes on it the stretch in the halyard will give far enough that the pole will bend at the socket.

The mono gin pole also depends completely on the baby stays... their pelican hooks should be checked carefully for a locked condition.

The block and tackle require a strenuous effort. When lowering, it was quite difficult to stop the process by cleating the line and then restarting it again because of the angle of the cleat.

Bolting a small trailer winch to the gin pole vastly improved it over the use of the block and tackle.

Any pictures or a description of its use somewhere here? I still don't get how this all works.

I think I just answered myself. And all along I thought the hole on the mast was to view the electrical wires!

Yellow = Gin Pole connected to hole in the mast bottom
Pink = Halyard
Green = Block and Tackle

Right?

I guess you could also run the Block and Tackle line back to the winches and winch it the whole way? (although it would be safer to stand in forward of the mast).

Hello,
This is the original mast raising system that came with early hull #'s. (1 thru about 200) This depends on a bolt arrangement inside the opening at the front of the mast. This provides a fulcrum point for the end of the mast raising pole to bear against. This crucial part had a tendancy to work loose or break off due to a poor design.

This arrangement works very well when the user knows the operation of all the components and they are all in working condition. We use on our boat every year to raise and lower our mast in the slip. It can be used with the boat on the trailer, however a third person may be needed.

I would be happy to help anyone interested in further information and drawings/pictures.
