I would like to see some more detail on the mast set up , fittings , spinnaker crane , and so on , could some one please post some pics . thanks

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

https://www.dwyermast.com/items.asp?cat ... =DM-4+Mast

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.

Dang, my phone flipped the photo. DM-5 on left / DM-4 on right.

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

Another view, complete with dead bugs from highway travel.

Dead bugs are FAST! This will affect your rating, ya know.

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.

Thanks everyone for all the help .

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:

painted the blades , sure hope they will work , I can always make more was not that hard just a bunch of work !!! Got three coat of primer on the hull.
cuttiing the ply for the deck so I know how much is left , still no floor or epoxy on the inside and everything else missing ,long list .

Looking good! Incredible progress!

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 .

today's work

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.
