Hi DP!
The poor boat just sits and stares at me now. How sad! That is very sad....but it doesn't mean you can't post here anymore....everyone goes through a dry season now and again... -- katysails s/v Chanteuse Kirie Elite 32 http://katysails.tripod.com "Women and cats will do as they please, and men and dogs should relax and get used to the idea." - Robert A.

self stepping my mast.
OY DP! Welcome back, dude!

One problem I haven't seen any of the others address is the mast falling sideways when trying to raise it. Our trailerable boat had a 26' mast with a rolled-up jib, I could lift it by hand but the tricky part was making the step up from the bridge deck to the coach roof. Our boat had a set of side babystays which I rarely used. These were secrued to loops on the lifeline stanchions so tha they were in line with the mast step pivot. I think that for boats without this feature, a loop of line on each side of th emast could serve the same function. Run a loop from somewhere not too far up the mast, like maybe the spinnaker pole hoop, to a block on the gunwhale forward of the mast step, then to another block the same distance aft of the mast step. Put another identical loop on the other side. Now the mast is free to pivot up and down but cannot fall side to side. You could use a ratchet block to help get it up. Fresh Breezes- Doug King |

self stepping my mast.
Hi Rick -- I've had good luck with a spring-type mast raiser instead
of a gin pole. It might apply to your boat as well. Here's a link to a discussion on another board. if you're interested, email me and I can supply more details/pics. == Paul == http://bbs.trailersailor.com/forums/...x.cgi/read/207 "rick" wrote in message ... I have found I can trailer my 29ft sailboat just fine and I can wetlaunch once I get the trailer galvanised but stepping and un-stepping the mast poses a problem in areas where there is no crane. If I make a tabernacle I need a ginpole or some way to get the mast through the 20-60 degree angle where I can't reach it and where the angle is insufficient for the forstay to lift it. Does anybody have any experience stepping their own mast? I have heard that using the boom as a ginpole might work but??? rick |

self stepping my mast.
I have a Bayfield 25 and have just completed a mast raising/lowering
system. It uses the upper shrouds to steady the mast laterally, and a gin pole. The boom is removed and the mast is toward the stern when down, resting on a temporary support structure. My mast is stepped on the deck and pivots on a hinge bolt about a transverse axis. I made clamps which attach to the upper shrouds at the same level as the axis of the hinge bolt. Each of these clamps attaches to the apex of a triangular strut structure based on the toerail. The apex is in line with the axis of the hinge bolt. The mast gets lowered toward, or raised from, the stern, and the clamps are free to pivot at the apex of the struts. I have to disconnect the upper shrouds from the chainplates, otherwise they would be bent sharply. The upper shrouds have only a bit of slack during this process, so the mast can only sway from side to side about 8". I leave the clamps on the upper shrouds, but dismantle the struts when not in use. I use a whisker pole as the gin pole, attached to the mast near its base. The jib sheet is tied to the end of the whisker pole and cleated at the mast so that the pole is close to perpendicular to the mast. The mainsheet tackle is used to pull the end of the pole to the bow, thus raising the mast, vice versa for lowering. During this process a long line tied to the end of the pole and run through the bow roller and aft to the winch on the coaming, acts as a safety device. The pole is prevented from falling sideways by a pair of shrouds of 3/32"" wire cable attached to the above-mentioned clamps on the boat's outer shrouds. That way the whole system pivots about the axis of the mast hinge bolt and the four shrouds don't get excessively slack at any point in the mast swing. So far I've used a helper, but it should be possible to do it alone with a bit of practice. Frank Stokes, Ottawa "rick" wrote in message ...

I have stepped masts on smaller boats (Catalina 22, S2 23' etc) and this is about 10X harder. We stepped ours using the crossbar on a travel lift as a lead for the jib halyard. It was tied to a pickup truck bumper which then drove up the ramp. |
