1960 18' Chris-Craft Continental

Chris-Craft made some pretty neat utilities. One of the sleeker, more sexy utility models was the Continental. Most years it came in three lengths; 18,20, and either 22 or 23' It's predecessor was the very popular Holiday model. In 1955 the company basically put more bells and whistles on a Holiday and called it the Continental. It's exactly the same hull, just an upscaled version.

This particular boat was purchased by a young professional who lives in New York. The bottom was already tired and needed replaced, then an accident occurred taking out one of the bottom planks. Now it really needs work. So, she's in for a new 5200 bottom replacement. She also needs some cosmetic work, but that will come later.

As a rule of thumb, if you can easily stick a penny in the crack between the original planks, she's going to have a difficult time swelling up. Here you could have stuck a small Volkswagen...ok, maybe not that. But the crack was more than ¼", way too much. There was also quite a bit of rot in the stem/gripe area.
After addressing the stem, we tighten all the carriage bolts, replace if necessary, degrease and clean all other structural components, and then seal with CPES and thinned bilge paint. Now she's ready for the 4m Okume inner layer. We seal the inside of the ply with CPES then attach to the structure with a healthy bead of 5200 and then use temporary drywall screws with washers to hold down. It takes several days to cure. This is a good time to begin fabricating and then dry-fitting the replacement planks, again using simple drywall screws as temporary fasteners.
We prefer not to steam planks unless absolutely necessary, but if you have an area that 'fights' you on one of the bends, you can lay a towel over the area and wet it several times a day. When you remove the plank prior to sealing it will retain much of the shape. Then it's a lot easier to put back down when the 5200 is on.
Apply a healthy coat of CPES to the outside of the inner ply layer, then let it dry overnight. Sam with the inside of the outer mahogany planks, including all edges. Don't worry about making a mess, get it all covered. The next day it will be ready for putting on with the 5200. Start with the keel strake, applying just enough for that plank (getting lots of ooze), then work your way down to the chine.
Once the bottom is faired, apply two coats of CPES, two coats of 2000e, and then two coats of bottom paint. Walla! Then it's done. Oh, don't forget to remove, clean, seal, and reattach the chine and bottom transom planks with 5200 as well. Otherwise you'll still get water.
