Fairline Squadron 78 refit/fit - Hard Top

Re: flag pole

we are so busy at the moment i'm flat out, but as I do I pop in & out of the forum when I take 2 seconds to sip my coffee, but the last thing I needed to be doing was scribbling designs. but just thinking of what might do it is a shaft with a continuous line inside that has the flags you want attached at spaced intervals and a opening slot at the top where the flag will appear. needs to be designed so the flags will pull past the wheels at the top and bottom without snagging... scribbled this.... no fancy design drawing but a musing to think about... and I have not gone back too many posts so if I have just lakesailored then I do apologise!

edited bit;

just read Colin's post.... same thing, sorry!,

Nice drawing firefly! Yes that's exactly what I've been kicking around in my mind (for over a year!) but the concern is about the scrunching of the cloth and snagging/jamming, as the retiring flag is dragged back inside the tube. With generous dimensions and the right sort of cloth it is probably do-able. The staff might have to be 75mm dia though, and you'd be investing a lot of effort building the prototype with just guesswork on the scrunching issue. Many thanks though

Alternative, to fix scrunching, is mount fags on a belt like the below. The belt has to be hidden in a box though. If you had just 4 flags, overlapped them a bit like louvres, and used 4 rollers so the belt doubles back on itself inside the box, you could get the belt box to 40mm wide (athwartships), 200 long and the ~same height as a flag. I don't love this idea though - am trying to think of something better.

if there was an internal partition top to bottom that would help with any snagging I believe.

but how about

Re: flag pole

How about an altogether simpler approach - each flag has it's own jackstaff. Just raise the required jackstaff and it looks like a completely conventional flag. No scrunching issues, and easy to separate the not-in-use flags from the current flag:

Re: flag pole

This sort of stuff is what makes this forum so good!

Re: flag pole

Just my 2 cents.

How about rolling up the flag on a vertical cylinder like infurl sails.
To have multiple flags have the cylinders mounted on another cylinder and rotate the apropriate flag into position to be unfurled.
This can all be easily motorised with to smalish motors or 1 motor and a clutch system.

Should be doable for 3 to 4 flags in a smalish footprint (size and material dependend).

To insert a new flag slide it in along the length of the cylinder , so you need something like a T shaped slot (where the T ends in an O)

My € 0.02
Using the ladder middle support gain access through a hatch -local moulder or Boats Uk ?
This way cleaning / other maintenance can be done too.

Bellow is I suspect a std boat -for refference

Re: flag pole

Hmm, the hatch is too hard Portofino. Thre is wiring and lighting to get in the way. You've been on mole sud recently - both those pics of my boat and lili are about 6 weeks ago ish!

Re: flag pole


I've been trying to find a use for this since I made it about 5 years ago. Originally it was part of a set of retractable undercarriage units for a very large model aircraft, that crashed. The unit was designed to be operated pneumatically but piston and cylinder could be swapped by a screw jack.
Hopefully the pictures will be enough to explain, but basically its just an over centre lock, with the piston pushed in it'll lock itself closed and pulled out it will lock itself open using just the mechanical geometry so no strain on piston.

Re: flag pole

I'm loving some of the ideas and have to agree with Jack about this forum! The great stuff just appears where you really don't expect it

As for the problem in hand, I'd probably opt to wait 5 years by which time there will be a holographic projected version and it will be changed at the touch of a smartphone icon...

Forgetting the hatch -mod the crane some how to gain safe access to upper surface of the HT .
Use it to hang an easily storable rope ladder -which may be clipped / tied to deck to minimise swing as a nominated volunteer goes up .
A good way to keep crew on good behaviour
Pic ,s Easter ish

Re: flag pole

What about a. variation on those toy guns where the flag pops out with 'bang' on it, you could have multiple ones , not sure how you re arm them though��

Re: flag pole

Maybe fit a quadcopter docking station on top of the hardtop, and glue a flagpole to the top of the quadcopter itself. When you want to change the flag you can carefully steer the quadcopter off the roof, then pick it up out of the sea with the tender

Re: flag pole

Now, why do I have a funny feeling that after suggesting to stick the c/flag to the most astern of the 3 poles supporting the H/T on stbd side (and call it a day!) I'd better run for cover...?

 

[Firefly625]

Re: flag pole

That looks brilliant Colin, I assume it raises and lowers in a smooth movement? Or can it also be used as a catapult?

I wondered that too lol :encouragement:

Good judgement on the need to run for cover! I hate flags just stuck randomly on things that weren't meant for flags. Gotta be on an official flag hanging thing in my book

Re: flag pole

Solutions to this kind of problem are often best resolved over a cool beer ot two - in the sun.
In my experience, though, the ideas become less plausible after the brain clears the next day.

Maybe there will be some suggestions from Carloforte later this summer when we can put all the brains together.

Re: flag pole

LOL, didn't I see that coming?
Frankly speaking, I'm with you on not considering kosher the arrangement I suggested - in fact, I hate for instance flags attached to VHF aerials.
But I must say that those steel poles look kinda appropriate...
...Maybe matching (no pun intended! ) the c/flag with a burgee or a guest flag on port side.
Ok, enough. I'll get my coat!

Re: flag pole

Everyone's missing the simple solution: employ a young person. All they need is a nice smart uniform (easily run-up on the sailmaker's sewing machine) and a bit of tuition on piping the owner aboard and mixing drinks...
