| Post subject: | Bottom job advise needed |
Bottom job advice needed. I bought yesterday 1994 Miracle. Upon inspection I found: 1. bottom of the hulls stripped off gel coat at about 1” wide 2. crack about 2”-3” long on stripped bottom of port full 3. edges of daggerboard’s wells chipped a bit Previous owner claims hulls not collect any water. Should I put layer of fiberglass on stripped area and then apply gel coat on top of it? Should I open crack and fill it up with resin? What to use to fill chipped spots? Should I use polyester or epoxy resin? Thanks, |

Upon inspection I found: 1. bottom of the hulls stripped off gel coat at about 1” wide Probably don't need to add glass to that - it's just the gel coat worn off from dragging it on the beach. I'm assuming the "bare strip" extends aft from the centerboard trunk. A picture would help. motogon wrote: 2. crack about 2”-3” long on stripped bottom of port hull Where exactly is the crack? Is is extending aft from the CB trunk? A picture would help here, too.motogon wrote: 3. edges of daggerboard’s wells chipped a bit Edge of the wells, or the daggerboards?Use polyester resin for repairs. It's what the boat is made of. Only use epoxy when obtaining good adhesion is a problem or where you absolutely need the extra strength. Polyester does not stick well to epoxy (don't try spraying gel coat over epoxy). For filling dings and fairing, Evercoat Formula 27 is a good, general purpose, polyester filling compound. |

It looks like the boat has been resting on a roller and that is what caused the crack. The H20 needs cradles or a full bunk to trailer. |

The dings around the daggerboad trunk can be filled with Formula 27, although the one with the deep hole looks a bit suspicious. I'd grind that out a bit with a Dremel tool to make sure all the damaged bits are out. Then I'd mix up some chopped glass with some resin to make a more robust repair. That crack is a big deal. This is the area that needs to be removed (minimum):  That lighter colored area inside the ellipse is delamination and needs to be ground away. Get out the disc grinder and go to work. You might find other delam under those black scuff marks. It really looks like the boat was put on rollers, which can cause this. Don't ever put a 20 on rollers! Cradles only! You'll want to use the repair techniques described in the "This Old Hobie - Blind Hole Repair" from the May/June 2008 HOTLINE - http://www.w1dm.com/projects/HOTLINE/08-05-06%20HOTLINE.pdf This boat looks like it was dragged over rocks. |
