Thanks. I can appreciate the gray area between art and science. Certainly, what looks good on one boat may not be appropriate for another. I'll ponder this some more. I have some time yet. Still working on the primer this weekend. Family from out of town visits this week, but when the time is right ...

Thanks Tim and Dave. I agree, it can look horrible. I will likely take her back down to the ramp and measure again with two adults in the cockpit. Originally, the cove stripe on mid-80's Com-Pacs is a 4" wide brown stripe bordering the rubrail running from the stern edge to roughly a foot short...

My Com-Pac 16's hull is cured of it's blister problem. Dried, filled, and faired. Barrier coat applied, even above the waterline where I faired with 410, per West System instructions. Will be using System Three primer with WR-LPU and VC Performance. However, I have lost my original waterline. Of cou...

I know this is a little late reply. For what it's worth, I use a cage type roller with the yellow West System foam roller covers. I have found it nearly impossible to remove the cover without making a mess of it. So, I let it cure. Next day I step on the cover and give the edge of the roller a good ...

My plan is to us VC Performance on my com-pac 16 (speed demon that she is). Really, she'll be stored on the trailer. I am curious if she'll accelerate more quickly. Had blisters and followed the West System instructions to a "T" with success. Of course, I faired the hull prior to the barri...

I, too, can confirm that DeBond works well. As mentioned, apply it where the 5200 meets the surface. Cut into the 5200 if possible. Used this method to remove a poorly bedded motor mount. 5200 was 0.5" thick at it's thickest. Simply waited a few minutes after application and removed with a putt...

I agree with the idea that the "shoebox" style of joint would be a good candidate for a glassed joint. The Com-Pac-16 has a flange joint which would be a bad candidate for such. 5200 and hundreds of tiny bolts. It's a small boat after all.

PGplastic

That is so cool. Thanks for the tip. 50/50 mix is my preference on my project. I can't help be wonder if the beige is more compatible with the darker wood of the Daysailor. What's the color scheme for the brightwork of your current project? I have very little teak on the CP-16. It's a very little b...

On the other hand I think the folks at Interlux are colorblind. I painted my nonskid with Interdeck beige and everyone comments on my new pink cabintop. Funny you should say that. I was concerned about the nature of their non-skid based on photos I'd seen. I was optimistic and chalked it up to the ...

Two part it is, then. Thanks.

Measured twice cut once. The compression post dry fits perfectly. Actually, I should give credit to a friend of mine who has his own woodworking shop by his house. Used to work for Drexel Furniture until it closed down. Skilled craftsman, he. Gave us a chance to catch up, too. Regarding the paint re...

Acetone: Also good for easing the forefinger-thumb clamp after supergluing two small parts together.

PGplastic

Yes, it appears that either shimming or milling a counter-angle will work here. I am leaning toward the milling option at the moment. Paint research begins. Thought I'd start with Interlux. I'm not too worried about creating more work for myself. As you can tell, I'm pretty good at it. But, I am con...

PGplastic

OK, so it's slow going for the newbie. ;) I do have the forward floor in place. I have successfully dry-fit the aft section of the floor as well. But, before I tab that section in place, I measured the compression post hole. The first photo of this thread shows the original set up. However, I discov...

It's been quite a while since my last post. But, I must thank all of you for the information and inspiration you provide on this forum!! Without your information I may not have tackled this project. As you already know and I can confirm with certainty, all things are connected. Long story short, las...

Thanks,

How's it going on the interior? Curious how you installed the new berths and sole. Hope it's close to complete. Post pics if you have them.

Another consideration: The edges of the awning can be cut with a slight concave curve. The corners will be a little extra pointy, but, flapping will be minimized once pulled tight. Kites often have this cut to the aft edge of the wing. Some mountaineering tents have the same edge, too. BTW, nice qui...

PGplastic

Thank you for the pointers. I will continue to practice (safely) as I finish the sanding and drying of the hull. My day job is getting in the way of my projects. :)

PGplastic

Quick update. I have been playing with the test panel of plywood and small batches of epoxy. Tried it neat, with colloidal silica, and 410 fairing. Am I glad I have!? Neat epoxy is pretty easy to work with. Bonded a block of wood to the plywood with the c. silica. Worked nicely first try. Fairing 41...

PGplastic

Well said. Thanks for your explanation and photos.

PGplastic

If I may add a question regarding the bootstripes. What are the criteria, if any, for choosing a double stripe vs a single? I noticed the "daysailor" has relatively thin double stripes and looks fantastic. Is there a time when that would look stupid say on a shorter boat? It's amazing to m...

PGplastic

OK. Here is a link to photos of work completed thus far. I think I'm starting to scare myself. :) Pictures will speak for themselves. Have had a fan blowing at the hull. Tonight it's blowing through the companionway and out two access ports. Trying to dry the nether regions of the interior, too. Jus...

Wow! She is Beautiful!!

I noticed the reflections in the finish.

Worthy goal to strive for such a beautiful finish. We'll see.

Great job!!

Thanks for the tips. Good ideas for efficient work.

PGplastic

Thanks for the information. Yes, I did order the metering pumps. The resin and hardener are group size B. I anticipate the mixed (unthickened) epoxy to be somewhat watery, based on the viscosity information I read. Maybe, it's more like warm syrup at this stage? I plan to experiment on plywood (even...

PGplastic

Hi all. I have just about completed my sanding part of my blister repair project. Ordered the basics for West Epoxy: resin, 206 hardener, various fillers for the future, and barrier additive. Also ordered mixing sticks, roller covers, but was unable to order roller frames, stiff brushes, roller pans...

It seems like several years ago Sail Magazine wrote an article about microbursts. One example they used was an event at Lake Norman, NC a local lake I like to frequent. It was a busy weekend when it hit, some say out of nowhere. Both power boats and sailboats were overutrned. Several people drowned....

Tim:
Thanks for your reply. I think we are "seeing" the same thing.

Update on my first project: I have sanded the bottom paint off and found more blisters than I can count. Have ground some, popped some, and scraped some only to find they are dry. When I grind the select few down to the fiberglass, I find small pin holes. Looks like most of the gelcoat needs to come...

PGplastic

Yeah. Great idea. Enjoyed the photos. I think it was in "Fastnet, Force 10" where I read that photosgraphs of the sea and waves tend to appear flattened, that is, the photos don't do the size of the waves justice. I couldn't help but notice in the third photo that the waves appear a little...

PGplastic

Thanks for the replies. I feel better knowing I'm taking reasonably good care. Hotter than Hades, that's OK. BTW, I've been vacuuming the dust up with a shop-vac equipped with a "dry wall" dust bag. That pretty much took care of the bottom paint debris. I've notice the paint dust seems a b...

PGplastic

I'm referring to materials used in repair of fiberglass sailboats. Specifically, regarding grinding old anti-fouling bottom paint and gelcoat. You see, my boat has blisters, well more like pox. Too many small blisters to count. I elected not to use a chemical stripper for a variety of reasons, so I ...

PGplastic

Thanks for the replies and the welcome. 'Tis true that they do what they were designed to do rather well; shoal draft and trailerable. I sail on a mountain lake, a larger lake down river, and plan to adventure into Core Sound and Pamlico Sound. Probably singlehanded or one other crew. Eventually, I'...

Hi all: My first post. I was wondering if you thought the Com-Pac yachts are considered classics. I currently sail a CP-16 (1989). Currently, this model is not in production as they are concentrating on different models. To me, they have a classic look. However, she does have "issues." You...
