Core sound 17

The tabernacle can rotate. It could be mounted in the mast tube just like a mast.

Just my $.02 worth.

Option-4 on the Mac. My 2¢ ;-)

Probably some combination of <shift-ctrl-alt-windows thingie> and 4 on less advanced machines.

[Gordy Hill]

Thanks!

I should admit you guys are greatly overestimating my computer capabilities.

(It took a while for me to find the dollar sign.)

[Dnjost]

Whoa! 9kg? That is considerably lighter than I imagined. Looks like the bottom also should weigh more than the top thus helping the balance for stepping as well.

17 seems to fit most of my criteria also considering shoppe space.

[Ken_Potts]

If I had the space available I would have built the CS20 but I'm really, really glad I didn't have the space becuase I think the CS17 was a better boat for me.

I sailed Southbound frequently in lots of different conditions. Probably 90% or more of my sailing was with just me (usually) or me and one other person. The boat was totally comforatble for 3 people and comfortable enough on the few occasions when I had four (or five!) aboard. On those occasions the sailing was social, so it didn't matter that we weren't moving so fast...

In addition to people, the boat carried lots of gear. I've been camp-cruising for as many as six days at a time, and we weren't shy about bringing along extra chairs and beer and whatever else we though we might miss.

I don't know about Global Warming, but I'm pretty sure gravity has increased in the last ten or twelve years.

I won't debate global warming with you, but you are surely right about gravity increasing!

[Dnjost]

This thread has been very helpful. I have a call in to B and B to order the plans for a cs17. Looks like a good fit for me. Masts should not be a problem due to the light weight and construction method. There are two other builders in the area as well.

[hokeyhydro]

Good choice. The CS 20 is a beauty but I estimate build time and cost would double. When I finally get going I'll build a CS-15 - would like a CS-17 but as our Designer told me on time: "The smaller the boat, the bigger the adventure!" Besides, my build space is cramped. A 17 would be a squeeze.

[Dnjost]

Plans arrived this week, wonderful service from B+B considering that they were just coming off the messabout!

This really looks very straightforward. Garage and workshop have been cleaned and now to secure materials. During the winter will start with blades, and masts, plus building cradle/table. I guess it's time to start a new blog! The builders CD is a real help to visualize all the rigging questions, and see the various steps involved in the building.

[ecgossett]

I have a friend who's a retired chief, and according to him my masts are pretty heavy (I didn't find this out until the beach at Fort Desoto). Of course my 6 & 8 year old can hold a CS17 mast pretty easily. These masts are nothing like a Hobie Cat or something similiar, weight wise.

The only thing that would have been nice on the builders cd was more detailed description on the photos. It seemed like the only ones that had descriptions where showing mistakes someone made. It entitled organizing photos in Picasa, then repeatedly going through, and adding keywords etc, as something jumped out at me. Or hours of searching trying to figure out good solutions.

I added a raised lip over the mainmast tube on Lapwing to help locate the mast base. Most will have no problem with setting such a small mast but I am more affected by increasing gravity than most of you. It helps in fitting the mast but will eventually need some modifications. I am going to increase the height on the forward edge of the lip and around the forward two thirds of the diameter to maybe 4 inches or so to give something to hold the base of the mast in place while I raise it. An easy way to do this would be to just make the mast tube longer and trim off the aft part above the deck. It can be prettied up with wood and will not be in the way of any rigging.

[Chick Ludwig]

Tom, that is what I did on the Mk-2. It really helps.

[Dnjost]

Does anyone know why there are wooden tops on the masts for the upper part? Would make sense to me just to make it all aluminum. Is it a cost or strength issue?

I am planning on sailtrack on aluminum spars seems to be the most versatile

Just wondering.

[Charlie Jones]

Designed to bend off- a wooden top bends more easily than an aluminum, plus far simpler to taper- go birds mouth by the way.

Oh and I'm gonna have to build new masts for Traveler, my trimaran. Graham called the solid masts "logs" and as I get older, I'm finding myself in agreement When I sailed the Tex 200, I had help stepping them

They weren't that heavy in 2008!! I was NOT 71 then either

[Dnjost]

I have a 22' box spar I made for a Bolger Birdwatcher in the rafters of my garage. Yup, it is pretty heavy. that is why it's still in the garage! trying to figure out a use for this other than a flagpole near the birdfeeders or a ridge pole for a tent. picking out a Dado blade this week for the 8" table saw to make the birdsmouth parts. Looks like fun.

I like the idea I saw above of leaving the main mast tube a little long and then cutting the aft end flush, thus making a bearing surface to catch the heel of the mast when raising it. Should work if the spar is balanced bottom heavy.

[makenmend]

No need of a dado blade for the birds mouth, I use a $9.97 freud diablo 7 1/4" 24 tpi in place of the 10". Practice cuts made on scraps to the same diamentions of staves, once your dialed in it takes no time.

I made one for my core sound 17 with taper to 1.5". using straight grain douglas fir. Came out at 27 lb.Os

I now have the aluminium masts at 12.7- 13 lb.

think I can still reduce birdsmouth weight but not to the level of aluminium.

May use that mast for a tradisional rig (Gaff, balanced lug) in the mid mast step position, just out of interest.

[Dnjost]

That is awesome. Thanks for sharing the photo. I can see that once it's dialed in it's a no brainer.

[makenmend]

Glad I was able to help for a change, it's usually me asking the questions.

MM

[PAR]

Even asking a question can be helpful MM. You're probably not the only one wondering about the issue you're questioning and of course in the future, someone doing a search on the same subject, will also benefit.

[makenmend]

quite often I cannot see the wood for the trees, the ability to come here and gain from the wealth of experience is priceless.

Use ALT-0162 or ALT-155 to get this sign: ¢

You have to use the keypad numbers, not the top row numbers above the QWERTY keys.

(How sad is it that I'm only able to answer questions about computers now? I really need to get back in the boat!)
