A challenge for you

Not commenting on your answers at the moment.
Only to say that there will be two more of these items.
The next two will be difficult to make due to an inconsistent profile.
Slightly larger as well.
I'm probably going to have a go tomorrow.
If successful, I will post some more photos.
 
Some sort of protection for bimini frame/rails?

This is what I was thinking ... support blocks for a bimini or folding roof of some sort.
Either that or swim armbands for someone you hope to inherit from.
 
OK so today's one nearly finished - just got to add the string ties.

And this is a template that I knocked up to check the sizes.
Its a bit of a pain making this stuff with the boats 1000 miles away.

Left over Shredded Wheat carton!!

One more to make tomorrow.
 
+1 on davit wrap ups to protect a tender
alternatively, they go under a hydraulic passerelle that lifts a rib tender to squash it down when underway (saves you properly tying the rib down - that's what I do anyway :-) )
 
The accuracy of the 7 sided template end bits is intriguing.
I can only think of masts on a sail boat having that profile .Or a crane jib / boom on a mobo , to protect it .

Otherwise he would have used say a 15 cm dia circle for a other boaty bits .
 
OK then, I've just finished making the full set - here's a pic

So, some of you got the answer correctly - Andy59 got it withing 30 mins of my posting.
Sorry I didn't come clean earlier but I wanted to finish them before announcing what they are.

So, yes, they are Davit Blocks but there were some good suggestions.
The background
The existing davits have recently been restrung.
They used to have stainless steel wires that hold the dinghy in place but have now been changed to Dyneema.
The change included larger weights to help lower them down to the dinghy.
The larger weights took up more space meaning that the tender couldn't be held firmly against the davits.
Hopefully, these blocks will fill the space.

As I said above, it is a friends boat but I did follow him once so here's a pic that should explain everything.

So, thats another little job that the Sailrite has done.
Recently, I made some sailing rope bags for another friend.
And another friend wanted some screens for his garden gazebo.
All these projects have used the white PVC - the same stuff that Princess use for their white PVC covers.
I managed to find the manufacturers of that material.
I have to buy large rolls of it but it is then really cheap.
It is also great to work with. I use double sided sticky tape for the joints and then sew through with the Sailrite.
Replacement cockpit covers for the boat cost over two thousand pounds these days.
I can make a set of covers for about a hundred quid.
So the Sailrite machine has actually paid for itself several times over.
I treat this as a hobby - gives me great little projects for the winter months.
