rigging

[Schoonner]

I can't find good resources that are advanced enough to tell me how to rig a self furling sail. Is there supposed to be a spring or something involved?

[michael pierzga]

Dont know. A spring would need a "Pawl" to keep the sail open then a trigger mechanism to furl. Might be complex on a model. Perhaps a mini electric servo motor pulling the sheet to open then a spring to furl. an alloy or plastic tube that is burried into the luff of the sail would allow rotation

yeesh! I think I might need a 10 channel radio. LOL!

A sloop without spinnaker has almost 20 lines to control the sails.
Are you sure 10 channels will be enough

All the manufacturers have the technical data on their websites.

[Schoonner]

DOH!!! I can't get to the websites for the k800. Should I try a different boat?

[gonzo]

Are you looking for a boat or a furler? Furler manufacturers publish their technical data, which includes exploded views and diagrams. What can't you get?

That might be helpful. I want to build a 3ft 1/8th scale K800 R/C boat since I can't have a boat larger than that on my rental space without igniting the wrath of the property owners and I will not need a trailer for it. It will be perfect for the pond at my RV park. I have most of the stuff I think I will need already for a project of that size and have already started cutting the first frames from pine. (It's kinda exciting!) I will probably be making an expensive radio made from parts of other radios I have lying around. Who knows, I might even be able to sell it for a couple hundred if I get tired of playing with it. I already have a 1920's schooner that I made from a wooden model boat that was not even meant to float.

EDIT:: I don't really think I need marine plywood for her, just fiberglass inside and out like a sandwich.

EDIT2:: It is actually only a little like the original plans, and does really well even without a drop keel since the rubbing strake is enlarged to displace more water if it heels too far and I drilled the keel and poured molten lead into the holes. It likes 10 to 15 mph winds the best.

EDIT3:: It went through a lot of testing where if my modification didn't improve handling, it was ripped apart and redone.

I'm running into difficulty with the scale. I based everything off the wrong measurements when I started because I only have so much wood to work with and now I don't know how to get the scale right from stem to stern and I have already started frames.

EDIT:: Lots different from working from a kit!!

[alan white]

The length to beam ratio will be the same. You need a calculator. You have the beam from the midship frame, right?

[Schoonner]

ahh that will probably workn! thanks!!
