Hello all, newbie here just saying HI and warning of numerous Q's :)

[21usmc47]

 Good evening,
 
I'm Mike and I am a  new Com-Pac 16 owner. It's a '79 # 886. I have very little sailing experience and have NEVER owned a boat before. I bought the boat last week and just put her in the water this Saturday. I had to clean the carb, add a battery and radio (my choice) last week prior to her maiden voyage. I've named her "The Midnight Hour." She came equipped with a stripped out cabin, newish rigging, and a home built trailer. I have to sink my bumper, an F-250 4x4 Diesel with  no lift to launch her. The sails are BEAT. I have sheets that are stiffer than these guys, not to mention that I think they are undersized. By my measurements (laid out on the ground and using an internet calculator)

- I have a Main that measures 54 sqft - 91"x171"x roughly 197";
- a jib that measures 35 sqft - 77"x138"x138" (I question the last measurement bc it matches the second and I text the measurements to myself);
- another jib that measures 56 sqft - 93"x176"x187"

all these measurements are luff x foot x "I don't know what it is called." The main seems undersized to me, by what I've read on the site and the boat is SLOW for sure. I know I have a lot to learn about sailing but I've been in quicker boats. I  plan on ordering new sail soon, can I get a main that has a foot that extends to the end of the boom?

Hi Mike and welcome.
   There are a lot of 16 guys here and soon you'll have more answers than you can shake a stick at. Of course, I don't know why you're doin' any stick shakin' anyway.
   I can't remember who did the song "The Midnight Hour." James Brown? Wilson Picket? Great song...love MoTown!
   Where do you sail?

The main will never follow the boom to the end of it. But the length of the boom is necessary for the end attachment and block for the main sheet. An in line four gang block might do better than a side by side four gang block. Less tangling of the main sheet in slack winds.
What I did on my CP-19 when all the sheets were replaced with the factory no stretch Sta-Set lines was to add and extra 10'-0" for both the main and head sail sheets.

All old lines and old halyards can be washed in a washing machine, and taken out after spun dried and tangled up into a God awful mess. That whole mess can then be submerged in the tub with some liquid fabric softener for a day and a half. Drain her, hang the line to dry and then sit down with your favorite TV show and un tangle the line for an hour or so. You'll end up stinking up the house and the GF will kill you but gently remind her that it is for the boat.

Now the head sail can be sized all over the board according to what I have read, and if the hull is fitted with a bow sprit.
Any sail loft worth their salt will have all the sizes for a Com-Pac 16 on the computer...heck you can look up the sizes your self.

Sails can be sent out and refurbished...I'd consider that before buying new, at least until you decide if this is 'the boat' and it's for keeps.

Cabins are pretty sparse on CP-16's. Just the compression post and a little carpeted deck to lay on. You bought a radio, what antenna did you fit? What O/B, and where is the battery stowed?
These aren't the slowest boats, about 5 knots on a good day. It's a calculable function of waterline and displacement.

Thanks for serving. Buy a copy of Bob Burgess's book Handbook of Trailer Sailing. His picture and CP-16 is the 'cover pic' on the Yahoo Com-Pac site.  You don't have to be a member to view this pic. It's kind of cool.

 Thank you Skip,

The engine is a '93 Mercury 2.5 HP, from what I saw Saturday it's plenty of motor for the boat. My boat does have a wood plank on the front that the previous owner said was for a bow spirit. As far as the cabin goes, it's bare. The previous owner stripped out the rotting wood and left just the bunk wood and the support for the mast with it's small shelf with the small hatch (I have no idea what that is for) I did find the anchor below that area. As for the battery mount, after reading a few post on this board I decided to mount it right in front of the mast support area and the horizontal shelf.

Mike, I just happen to have a measuring tape and a set of sails for my MK-I CP-16 lying around the garage, so I figured this was as good a chance as any to finally get around to measuring things...

The sails I measured are by my guess the ones that came with the boat back in 1975.  They are WELL USED, so any measurements may have to be taken with some margin of error.  Additionally, having purchased new sails, I know that the new ones rig slightly differently, so there are some differences (mostly I can tell by the foot on the main, the new one seems a few inches longer).  I still use the genoa regularly, to include this past weekend, and none of the old sails could ever be confused with being "crisp."  All that being said, they seem to match pretty closely to your first set of sails measurements, but not the second jib.  Since the luff of the jib is restricted by the length of the forestay, perhaps that second jib is from after applying the bowsprit and/or the MK-II which went from a 3/4 rig to 7/8 (if memory serves)?

Regardless, here's what I have:  Mainsail was 172" (14'4") in the luff, 90" (7'6") in the foot, and 202" (16'10") down the leech (some fudging, my tape measure stopped at 16').  Close to what you measured, and the different versions used the same mains.


The jib, which I believe to be a 110% was 137" (11'5") in the luff and leech, with a foot of 78" (6'6"), which is darn close to your jib measurement.


Finally, the genoa, which I believe to be a 155%, was 141" (11'9") in luff and leech, with a 118" (9'10") foot.  The similar luff measurements make sense due to the same stay restriction, and I do notice that the genoa does get ever so much closer to the mast than the jib, so the 4 inches are noticeable.


I did buy new sails last year, but rarely have used the new jib.  Sorry, can't measure them as they are up at the boat.  The new main foot is slightly longer than the old one, but also much "crisper," and I had to cut about an inch off the front of the boom to put in a new gooseneck.  In any case, it definitely reaches further back along the boom.  See me fiddling with it here (nearly reaches the end of the boom, the new jib is folded at the bow):



So, not a lot you can do about the size of the main, unless you want to get a new mast and boom :-).  New sails will make you faster, and with a corresponding increase in heel for a given amount of wind (doesn't spill as much as the old sails) which adds to the fun. 

Welcome aboard,
-Justin

Does anyone know what this might be??

Hopefully that image shows up. It's a block, if you will, attached to both of the "side stays??" that support the mast. They are located about 12-18" off the deck and interfere with the jib as I'm tacking back and forth.
Skip, the antenna that I used came with the radio. It's of a soft design and I just laid it on the shelf that the radio is mounted to. Surprisingly I pick up all the channels that I listen to.

[21usmc47]

So that attempt didn't work. Thanks for the test page. Here is the photo.

[Salty19]

No idea what that is.  Maybe a jackline lead, but that's a wild guess at best.  I would remove it to avoid interference.

[skip1930]

You can delete the second attempt showing the photo of the mystery thingy. And modify the first attempt with the propper 'direct code' out of Photobucket.
Then save the corrected post. That way we don't have so many posts under one heading. Or correct spelling or adjust the verbage to better describe the point being made in the post.

Hey Mike:
Those fittings look like they might be for mounting a tarp or awning over the cockpit.  They look like a rod would fit through them to hold the front edge of a shelter, they also seem to be the right height... between the cabin and the boom.  They are not stock.

If you search this blog there are several previous posts on sail size.  I spent a couple of hours last year just reading through all the C16 stuff,even though it was tough for a Marine because my lips got tired from moving them as I read!
