Laser sailboat paleontology
I am rebuilding a Laser sailboat made in 1975. I had a bare hull with
NO fittings at all on it, mast, boom, a sail, dagger board, broken rudder, and a box full of blocks from various boats, some may be Laser parts. So far, I have replaced the deck acess port, self bailer, fairleads, bow fitting, grabrails. I do not have another Laser for comparison to see what I am missing or what should go where. Fortunately, there are stains and holes marking where fittings screwed to the hull so I have been able to decipher most of it. I am uncertain about some things because they seem to differ on this old boat from the more modern versions. The boat seemed to have clamcleat style cleats on either side ofht ecockpit instead of camcleats. Could this be right? There is no tiller and I am loathe to spend money on a new one so I may make one. Looking at the fitting for the tiller on the tiller box that holds the rudder, there is a squareish mount for the rudder. Did a wooden rudder simply fit into this? The pin that fits into the top of this through the steel mount on the rudder box, was it simply to hold the tiller in place? What kept the pin from coming out? How long should my rudder be? This hole looks to be no more than 1'X1" which seems sorta flimsy, what about this? The cord that attaches to the forward edge of the rudder may be to haul th erudder down after launching but I am not sure how to lead it. I have downloaded a rigging manual for a newer Laser but it doesnt tell the lengths of the various lines or their size. Can anybody tell me this info? Thanks, David OHara |

I've only sailed a Laser once, (Didn't like it.) but I assume you're
familiar with Annapolis Performance Sailing. Their catalog and web site include diagrams and parts lists for Lasers. http://www.apsltd.com/Tree/d3000/e1236.asp gives a diagram of deck fittings and parts lists. Other pages show rigging and sails. You might also check out "The Laser Book" (Sail to Win Series) (Paperback) by Tim Davison at Amazon.com. If you're planning to race in "Class" races, then line lengths are important. (Too long gets you disqualified.) If you just want to make holes in the water and enjoy the scenery, then adding a little to the sheet length makes life more comfortable, or at least it did with the Sunfish. With the Sunfish, competitors went to extremes to get those extra inches; e.g. using a simple overhand knot to secure the standing end with stitching to keep it secure. Have fun.

I do have an APS catalogue and have ordered parts from them but I
cannot find anyplace that specifies what size line to use for various things. This Laser is so old that it is somewhat different from newer ones as shown in the catalogues. For example, the new gudgeons did not fit so I had to fill the old screw holes and make new ones, the deck access plate was an entirely different size, etc. There also seems to be a lot of slop in the mast step. Is this correct? APS does have some material to take up some slop but the mast step on this old boat actually seems to be slightly oval with long axis along the boat axis so the mast can tilt forward or back. This could radically affect sail trim. What really strikes me is that my strengthened MiniCups are probably better built than this old Laser. On the Laser, they simply use screws into the underlying wood to hold fittings instead of using backing nuts. How often do these fail? |

From APS' web page http://www.apsltd.com/Tree/d3000/e1187.asp :
Polilite Mainsheet by Rooster Ropes UK snip We recommend 46' for a Laser mainsheet, though between 42' and 48' is the norm. Also available in a yellow 5.5mm for light air. Purpose Length Dia. Line Type Mainsheet 46' 5/16 Polilite Rooster Ropes Vang, Cascade 5' 1/8 Excel D12 Vang, Cleated Line 14' 5/32" Swiftcord Cunningham, Cascade 3' 1/8 Excel D12 Cunningham, Cleated Line 14' 5/32" Swiftcord Outhaul, Stock Cascade 10' 1/8 Excel D12 Outhaul, Cleated Line 14' 5/32 Swiftcord Outhaul, 6:1 Block/Mast Tie 2' 1/8 Excel D12 Traveler 11' 3/16 Tech 12 Rudder Downhaul 5' 5/32 Prestretch Clew Tie 2' 3/16 AmSteel 12 Hiking Strap Line 4' 3/16 Prestretch Centerboard Shock 10' 1/4 Shockcord Hiking Strap Shock 2' 3/16 Shockcord Mast Retainer 3' 1/8 Excel Racing ************* Depending on your goals, you can probably substitute cheaper, fatter lines. Personally, I like 3/8" minimum for the sheet. Your hands won't hurt as much at the end of the day. Size your blocks and cleats appropriately. APS seems to offer several different packages, but I'm too lazy to extract the others. I'd guess that the elongated mast step might be a gimmick to adjust the rake for the minimum acceptable weather helm as a function of breeze and sea-state. Check out http://www.laserinternational.org/rules/ilcarule.htm for details. They seem to be the source for APS' diagram of the Laser parts. IMHO, the Laser seems to me to be a toy for erstwhile America's Cup racers. All the go-fast gadgets that will decide the race if and only if you're one of the top 1% of Laser sailors and very lucky. Remember, "All the boat speed in the world won't beat dumb luck." As I said, my total Laser experience was a short solo sail to pick up the buoys/marks after a day of racing. This was ca. 1975, so I don't remember a lot of details. Too many strings and gadgets. In the heat of battle, your attention should not be in the boat and ... For a fun day on the water, the Sunfish is both cheaper and better. As to the lack of backing nuts, the handle on the bow of the Sunfish came apart in my hand after thirty years. The pot metal disintegrated, but the screws that held it on were still functional. Also still effective were the two little screws holding the halyard turning block to the deck. (The "old style" rudder mechanism was never right.) Part of every boat building project should be the "Rigging Warrant" which details the line sizes, blocks, cleats, etc. It's a good spreadsheet project, particularly for those planning a junk rig. (The sheets go on forever and have to be sized for sailing wing-and-wong.) Roger http://home.earthlink.net/~derbyrm wrote in message oups.com...

A pin in the hole in the top of the rudder will keep the tiller in place. A 1x1 hardwood tiller is fine. The pin is attached to the tiller with a bit of string. I can't remember if I've seen aluminum box tillers on lasers, something with a black finish is popping into memory fom the 1980's. If you live near the water a walkabout at a sailing club on the day of the week the lasers race should prove enlightening. -- ------------------------------------------------------------------------------ William R Watt National Capital FreeNet Ottawa's free community network homepage: www.ncf.ca/~ag384/top.htm warning: non-FreeNet email must have "notspam" in subject or it's returned |

Thanx to all. I may just order the tiller in spite of the absurd cost
(95$ from APS). |

Over the cost of a piece of 1x1 that you can make look REALLY pretty?
