1980 AMF Sunfish SUGAR 2 21 Feb 18 Hull Repair and Inspection Port

21 Feb 18:

Sanded the splashgard with 120 grit and gave it a coat of Rust-Oleum.


SUGAR 2 deck gouges from the boom bolt, almost all the way though the gelcoat.



One of our old standbys, Marine-Tex epoxy putty. We used this today because it will be a close match to the gelcoat on PHOENIX. It will be a little too white for SUGAR 2's cream colored deck, but may fade over time.


Marine-Tex applied.



Fiberglass damage in SUGAR 2's daggerboard trunk.



Mixed up Pettit Marine Paint Flexpoxy to repair fiberglass damage in the daggerboard trunk. Totaloat THIXO is a good product for this repair as well. Used the half wide paint stick to trowel Flexpoxy over the damaged areas, anywhere the outer layer of polyester resin has flaked off. Also injected epoxy from a syringe into the seam voids we found a few days ago.


Inspection port installation between the daggerboard trunk and splashguard. The tape protects the deck from the jigsaw footplate.


The inner plate makes a good template for the inspection port hole.


Marked the hole, drilled a 1/2 inch hole inside the circle to insert the jigsaw blade. Cut on the line with a DEWALT jigsaw.




Inside the Sunfish hull, daggerboard trunk.


Inside the Sunfish hull, mast tube and wooden backer block on underside of deck for the halyard fairlead. White blocks are the structural and floatation foam, yellow foam is the expanding adhesive foam. The fiberglass strip at the top is the strap that used to hold the wooden halyard cleat backer block. It rotted and fell off.


Someone moved the halyard cleat at one point, probably to find better purchase on the old internal backer block. We used the cleat to predrill the 2 screw holes, then epoxied the block and put it inside the hull in the original position. Then we used the drill bit to find one of the screw holes and line up the block for the first screw. Once the first screw was in place we removed the drill bit, swiveled the cleat and inserted the second screw. The epoxy oozing out of the wrong screw holes is good news, means we had plenty of adhesive contact between the block and the hull.


New halyard cleat backer block, made from rot resistant cypress and coated with epoxy. Held in place by thickened epoxy and screws.


We pre drilled all of the machine screw holes using the ring as a template then removed it and put a bead of sealant around the port hole. The port was put in place, then twisted a 1/2 turn to evenly spread out the sealant. Machine screws were reinstalled and secured with nylon stop nuts.


Installed a swivel cam cleat. Test fit the coaming.

Barbashela Log 06 Jun 16

06 Jun 16:

The surviving lower broad and mid broad planks on the starboard are 3 inches wide and were butted to the aft planks. We removed the broken sections and cut 2 new cypress planks to fit. They were fastened with silicone bronze screws and trimmed to fit into the stem. The plank stock was 12 to 16 feet, so we used an 8:1 scarf to make the 20 foot runs stem to stern. Scarfs were glued with Pettit flexpoxy.









For the the new piece of the top broad plank on the starboard side, we took measurements every foot between the sheer strake and mid broad plank. Then we transferred the measurements to a piece of pattern plywood and trimmed it to fit. Once it fit we transferred marks to a new cypress plank.


The top broad on the starboard side had a shattered end, so we fashioned an 8:1 scarf with an oscillating tool.





Working around the bow, took the opportunity to trim the inner stem.

For the portside top broad plank we took measurements at every station from the sheer plank to the mid broad plank. We recorded Feet-Inches-Eighths on a paint stick then made templates from pattern plywood. Trimmed the plywood to fit then cut planks.











Carpenter bee fun!


Last plank scarf.


Whiskey plank.





Template for the breasthook.


Gotta fix the sculling notch, it's too fancy according to the Skipper and another subject matter expert.






Caulked the planks with 1 pound of Bristol Sussex cotton, also a little wicking in some areas. Painted the caulked seams with alkyd enamel (oil) to seal the cotton.








Cleaned out the starboard garboard seam and filed down corroded areas for dutchmen.




Posed for pictures.
