Re: Reefing Line Attachment

Two things you may wish to consider - with the reefing lines dead-ended at the luff cringles, the cringle likely will be pulled off to the side of the boom where the turning point is. If this is not a problem for you, then that's not a big deal. The second point is that by having the reefing line de...

Re: Lowering Halyard Resistance

I suspect your proposed solution would actually have more resistance than your original arrangement, because the rigid (mostly) ring would tend to lift ONLY on the side where the halyard is attached. The opposite side would not rise and the ring would then be tilted, jamming against the mast. Perhap...

Re: Reefing method question.

Lindsey, Absolutely nothing! The only thing you're missing is the name of this kind of rig - it's called a jiffy reef. If I may add, you may find friction in the eyestrap port side forward and starboard side aft to be a bit much. You may want to put small blocks (cheek or bullet) there (similar to w...

Re: Mast bend

If you're into Duckworks, may I suggest that you consider using the carbon fiber tape they sell vice the fiberglass braid. You can view the short video there about application. If you've got a bird's mouth mast you could lay strips of the tape along the length of the mast (parallel to the axis), spa...

Re: Mast Building

Pete & Christine; Respectfully, I disagree with the need for weepholes/pressure equalization. The physics of moisture ingress and pressure differential are such that neither is a concern. The following post provides some clarification: http://smallcraftadvisor.com/message-board2/viewtopic.php?f=3&t=...

Re: SCAMP Yawl #2

If I may, a yawl rigged SCAMP would not be too different from a Welsford SCAMP antecedent - the TREAD LIGHTLY. While the original TL had a larger-ish cabin, the following link describes one builder/owner's modifications to a TL to make it almost "mistake-able" for a SCAMP (with a yawl rig): http://w...

Re: Hollow mast venting

I respectfully disagree with the position Kenjamin has taken regarding moisture inside a spar. If a spar is completely sealed with epoxy inside and out (and usually coated with either paint or varnish on the exterior to protect the epoxy from UV) and it is not submerged in water, atmospheric pressur...

Re: Hollow mast venting

The Universal Gas Law states that P*V/T = k. P is pressure, V is volume, T is temperature (in absolute degrees - either Kelvin or Rankine) and k is an arbitrary constant. So, we can consider the volume constant (i.e the inside volume of a finished hollow spar) and then P/T = k/V (or a new arbitrary ...

Re: Zephyr Cruises

I almost hesitate to mention this, but the reefing can be done using a single line for each reef. Dead-end the line at the aft end of the boom, go up through the leech reef grommet, back down to the boom, through a turning block so it leads forward along the boom to another turning block at the forw...

Re: Outhaul hook vs reefing lines.

Sorry Howard, with all due respect, if you want to stiffen the boom in a vertical dimension, you SHOULD add the fiberglass to the top and bottom. Consider modelling the boom as an I beam with the flanges at the top and bottom (which is how you would do it if you were using an I beam for a boom). The...
