Need measurements.....1982 19

[blowndown]

New member here.....
Just looking for some info on my restoration project. I have a compac 19 1982 model that was purchased for 300$ with a trailer but was missing a mast/boom and needed a fiberglass patch on a lifeline stantion base. Most everything else is cosmetic. I have recieved a price list from compac but am trying to adapt a mast from a Southcoast 22 to work and save some $$$. I'm looking to get a mast lenght and the standing rigging lenghts. Any kind of help would be great....

The following measurements were taken on my 1984 CP19 mast and rigging. It is not precise but as close as I could get it measuring by myself using clamps for a third hand. The rig measurements were complicated by PO's use of jury rigged attachments. Also if the masthead is substantially different form a standard Com-Pac (about 2" form spar end to shackle pins), then compensation must be calculated. I think the turnbuckles could probably handle most of it

I have the boat in my driveway and the rig in the garage so just ask if you want something else measured. For clarification call me at 336-768-0148.
In fact if anybody needs a measurement this is the time to get it, just ask.

Mast Length  = spar itself, add masthead and footplug

Pin to Stud = upper shackle pin to end of swaged stud, add turnbuckle and lower stud.

Pin to Pin = total length including turnbuckle assembly adjusted to fit, as removed from boat.

249" = Mast, spar only
2 1/4" X 3 3/4" Mast cross section
256" = Forestay, Pin to Stud
294" = Backstay, Pin to Pin (This was toughest of all due to bizarre fittings)
247" = Upper Shroud, Pin to Stud
135" = Lower Shroud, Pin to Stud (Spreader attachment fitting adds another 3")
131" = Spreader Height from lower end of spar
29"   = Spreader Arm Length including attachment fittings, each
1 3/4" = From spar foot to hole for throughbolt


Happy Sails,
Jim

Some of these numbers I did not know but may have thought about them once in a while. Additionally I have in the GALLERY under SKIP's PICS a scanned listing of general items concerning the Com-Pac 19 XL. skip.

Aw Shucks! Thanks Guys!
Happy to help and trust me, when I get back to working on my matched set of Cp 19's, I'll have plenty of questions. Gotta tell ya, it is tough having two new boats and no time to work on them, much less Sail them. maybe next week.

jim,
thanks for the measurments and sorry this came so late. my buddy invited me to do a crossing with him on his 40 island packet, got to respect Bob Johnson and his classic contemporary designs. Any way Jim the measurements helped out a lot according to my math I can use the 25 ft mast off a Southcoast 22 with the sails but I think I will remove the southcoast logo. Anyway I will add more to this when I get home and post more but I'm on a marina computer and they have a 15 min time limit. Got to run.....Happy sailing....

Top'O Masthead to Com-Pac 19's waterline is 25 foot. Then I add 30 inches for my radio whip. In this site's gallery is 'skip's Pics' and some tech facts about my C-P 19, as I typed up this sheet and scanned it to my gallery.

Give these pictures a look~see. Somewhere on my Ships Notebook and log'  are the dia, and shapes of the mast and boom.  WHAT FOOT PLUG? It simply is the Tabernacle that a bolt, washer, and thumb screw goes through. It's just a drilled hole in the bottom of the mast. The hole size can be ascertained by the hole in the [existing ?] tabernacle.

Dwyer I think sells the 'raw' aluminum extruded tube to make masts.
The proper masthead aluminum casting that plugs into the mast tube and is 3 inch high overall with sheaves and fwd. ring can be ordered from Com-Pac.

What you need on a Com-Pac 19 is...

~A mast tube that is 249 inches long. With a 3/16 inch wide slot for the sail cloth to slide into. Slot wides once in side the tube for the rope sewn on to the sail.

~That is 3 inches long oval bow to stem.

~That is 2 inches wide oval port to starboard.

~From the  bottom end of the tube to the BOTOM of the 7/16 inch dia bolt hole going through the mast's dead center, and lined up with the tabernacle's vertical slot is 1 1/2 inch above the base plate of the tabernacle or from the end of the mast. Same thing.

A slot in the tabernacle is necessary as the mast pivots going up...it rises on it's edge and then drops down onto the base of the tabernacle when the mast is vertical.

The standing rigging from chain plates to top-O-mast and through the spreaders can be left on the mast when lowering or raising the mast. Just back off the back standing rigging and make the forward stay tight when the mast is straight up and down. Then tighten back stay.

To adjust the standing rigging lay in the vee birth and peer up the mast through the forward hatch. It is amazing... one can see the mast bend as the standing rigging is played with. Make her straight.

~The boom is 111 inches long. Add about 1/2" for cast plug at it's end.
~But a Com-Pac goose neck so she'll fit the mast and down haul.
~Same slot as the mast.
~It is 2 3/4 inch vertical.
~It is 1 3/4 inch wide.

That should get you started. skip.

Well it's great to be back.... Have a question for all you guys... I have a southcoast 22 mast that is 25 ft long with a longer boom that will work on my mastless 19... Would you use this taller rig with about 4 sq ft more sail area, or cut the mast down and order the "correct" sails, or order a mast from dwyer or com-pac?

[B.Hart]

I am currently sailing with a snipe mainsail, so I believe in doing what ever it takes to get on the water(and cheapest sometimes) HAPPY SAILING   BILL

[blowndown]

I believe you are right in getting on the water asap... but I'm not sure if the taller rig would create any adverse/dangerous conditions with the balance of the boat. Anybody have marine engineering background that might be able to give advice on this....
any help would aid my decision...

[B.Hart]

Even if the rig is larger you could still use a smaller sail, just thinking out loud.   HAPPY RIGGING   BILL

[Deborah Klaus]

The standard boat is under-rigged and over-ballasted...go with the taller mast...she will have zip!

[Craig Weis]

Ms. Klaus, the rig regardless of vertical height may not push the hull any faster...as the formula for this Com-Pac 19 hull shape, length, width, and weight pretty much remain unchanged no matter how high the mast. So I'm thinking that the calculated hull speed will remain...what 4.2 knots? or around 6 mph give or take? I'm not going to recalculate. What say you? skip.
