"I have changed the original concept by balancing all sails fully, so that the mast is roughly in the center of the sail. Like this, there is very little stress on the sheets. For an illustration of the idea, check out Maltese Falcon"

"Looks nice, Paul, but the bolts are too short. Your need space for washers and the thread should protrude a bit. Are you using tinned wire?"

Wharram with two masts on each hull, schooner configuration

We are speaking here of un-stayed masts buried in the hulls, carrying junk sails of moderate size. 4 sails of 15 m2 make 60 m2, while it needs 30 m2 sails on two masts, or the same on one mast. High aspect ratio, that means a square sail of 6 x 2.75m with 8 battens and 4 sheets, built very light. Reefing for heavy weather by binding 2 battens together, so stiffening the sail (reefing from the top).

Well, I have done and tested it. Broke 4 test masts in the process (glass/epoxy).

Hi Hans

 

I am not there at the moment which kinda sucks - gotta earn a bit of money before I take her sailing. Are you local or cruising?

Hi Hans, It was a pleasure to show you SeaShoes. The storms were fierce but we did not suffer damage- although we had to help some other yachties to ovoid the worst of it.  Please send us your contact details as we would appreciate information regarding the long shafts for oiur outboard motors.

Hi Anne, You find my email address on www.phefo.com

I have sent some details to Jannie, otherwise just email me and I will send you some links for the long shafts.

Hi Hans!  My build is coming along rather slowly.  Had decided last year Nov to purchase a tiki 26 with a friend, Rob Stuart-Hill.  We bought Jabberwock from Etienne deKock in Cape Town, and I towed her through to Durban three weeks ago.  Currently doing cosmetic maintenance while we wait for a mooring.  Keen to go sailing!

Hans goodday, how u doin.

I have read ur posting about the mast being made of plastic sewage pipe,

can u pleez supply more info on the construction of the masts. Especially how u got the epoxy & glass to stick to the plastic. I am thinking of sumthing along the same line, using ridgid plastic pipes that fit into each other with a very close tolerence.  

Thanx Iain

At 1:58pm on August 19, 2012, Hans Hammig said…

Hello Iain, The pipes are of the expensive tough plastic that does not break. 90 mm diameter. I cut the connection pieces off and glued the pipes together with with structural epoxy putty. Then put an electric cable outside, then glassfibre and epoxy outside, always a full sheet 130 cm wide and full length of mast (ca. 9m), which I rolled tightly around the pipe. I had sanded the pipe with 60 grid. I used 200g/m2 weave and 600g?m2 weave in layers of full length and width, a total of 10 kg Matrix Eopxy and 20 kg glass per mast. I post cured be packing the mast in black bags and placing in the Sun for two days. It was a monumental effort. Thickness of the laminate is about 9 mm.

Regards, Hans
