Dwyer has a great website as far as product supply is concerned::

DM-4 is on the left / DM-5 is on the right. I didn’t see a huge advantage to the DM-4 so I went with DM-5. Plus I was lazy and decided to go with just one set of spreaders. In the conditions I’ve been in I haven’t noticed the rig deforming to leeward.

Masthead I made out of 1/4” thick G-10. It seems to be holding up fine.

Tim, is that a 2 to 1 main halyard or a topping lift?

Thomas, here is how Slightly Barbaric's mast foot was rigged. It appeared to be a Dwyer section, sitting on a plug on the coach roof rather than a Dwyer tabernacle.

Picture quality isn't great as I hadn't anticipated posting them, but they suggest how halyards can be led to the coach roof.

Warren, it is a two to one halyard. I like too. Currently, my Jib is one to one. I’m going to change that to two to one.

Still working on the centerboard ,a lot of steps and it has to be done before I turn the boat back over , I glued Hobie fiberglass battens on the inside of the centerboard trunk to give the board a rail to run in and out and keep it from shaving through the glass. .and working on the board .

A selection of aluminum and CF masts. Many of the links still take you to the company websites. There was former builder (Dennis - #32) that had a stick on Lake Lanier and another former builder (#336) had a stick in Savannah. I' went with a Viper mast since it was a great price.

I used the Dwyer DH104 masthead. This unit was designed for a single halyard but I cut a slot in the bottom of the unit so that I could use two halyards with it. This has been trouble-free and was a pretty easy modification. I used the Dwyer base, and the large halyard organizer plate. You can see the base and halyard organizer plate in this picture:

A friend of mine called me up and said he had 3, 2x10x 16foot sitka spruce or yellow pine and I could have them for the boat project . Not really sure about the difference,its very light and bendy .This wood has grain about 32 second wide .
supporting the cockpit floor , having to invite my fat friend 260 lb. with no lead keel I needed a bit of lumber .
Nothing is more annoying then a soft cockpit floor .
Also getting ready to install the chain plates.
My shop is a huge mess ,running out of room to store parts that need to get installed .

Thomas, those transverse stiffeners for the cockpit sole just forward of the 'rudder bump' are a good idea. I didn't do that and my cockpit sole is a bit too flexible in that panel. I don't think a single layer of glassfibre sheathing will do much to stiffen it.

Do you have an army of elves working in the background, or are you just a super efficient worker? :-)

You know Warren I thought about Carbon fiber instead of wood , but really could not tell till it would be done ,and then the wood came my way and answered that question .
I did buy extra Carbon for the deck and will try it ,its higher up from the waterline and I will let you know how it works out . I am not rounding the cockpit seat area , I tried sitting down and my legs clear the edge ,also bending an inverted curve is more then I want to deal with .
I am working alone ,all day, owned many boats before , built out an 35 foot steel cutter and crossed oceans with it . I am fast working ,yes I make mistake ,but you know
the art is to fix them in the best way . I am just another epoxy wood butcher . Tomorrow I will start on the floor ,cabin sole , start painting the inside with 2 coats .

this morning I had this idea to use Hobie Cat dolphin striker support rods to give the chain plate triangle more support , hope it will help can't hurt .Cut the floor panels
only going to put 2 in front of frame 124 and 2 behind ,mostly storage and a flat survive just makes stuff slide around .
I found a viper mast hoping to pick it up in the next 2 weeks .

Thomas, it is purely a gut reaction but your mast step compression post looks a bit spindly. Is it just a placeholder to be replaced by something stouter, or is there carbon fibre reinforcement to come? If it buckles under compressive loads the mast will punch through the cabin top. I could be quite wrong and it has been 30 yeas since I have done an Euler buckling calculation. :-)

Otherwise, you continue to shame us all with fast, good-looking work.

Thanks I will make a more stout mast step post .

I need some info on the rod receiver and the carbon spi pole . where to get them ,how to make them ,and how to rig the blocks once it is all done . I thought about just using a windsurfing mast with a bob stay ,but not sure now ,it could be nicer .Also thinking about rounding the seat now , its just becoming a great little boat .

Thomas, I got my spars (mast, boom and prod) from Competition Composites in Ottawa, Ontario:
http://www.fastcomposites.ca/site/
I made my own prod receiver as shown in my build log.
Some people also got this stuff from C-Tech spars in New Zealand
There are probably a few US suppliers as well.
Have a look at the Harken web site. They have some good 'rigging guide' pages that will give hints on how to rig an asymmetric chute and prod.
Because I will not have a slewing prod, and will be launching my spinnaker from a 'sock' through the foredeck, I will be rigging my spinnaker-related stuff much like a 49er.

I wrapped the compression post with 4 layers of carbon !
2 coats of epoxy in the whole boat and a little more deck support , extra carbon for the chain plate bracket . I also coated the deck wood on the under side .made the bow
fitting .
Few days brake now , next week I will start with the deck gluing.
