1965 Alcort Sunfish WAVE 09 Dec 20 Deck/Hull Seam Adhesive

09 Dec 20:

Sandbags off, deck shape looks great.


I should let Skipper order fabric, she knows what she is doing and I MIGHT have over-ordered. 5 square yards of 6 oz fiberglass cloth and about 12 square yards of woven roving. Might be able to build another boat.


Jamestown Distributors sends out these nice mixing cups, and we highlight the ratio we are using so we can find the right column easily while pouring. Today it was 5:1 Epoxy. Resin to Hardener. Ignore the last 1.


We used Great Stuff expanding foam to adhere the top front of the structural blocks to the underside of the deck. It will work fine as long as we don't let water fill the hull for extended periods, it is not closed cell and would eventually absorb water. We used it here because we didn't want to split any more seam than was already split, and the deck could only be raised so high.


Put down a bead of THIXO Wood thickened epoxy then laid a one inch wide strip of fiberglass cloth. The cloth helps distribute and hold the epoxy in the seam, a tip given to us by Howie, who repaired built Sunfish for 18 years at Alcort then AMF, and then did another 10 years of warranty repairs.


Skipper wet out the cloth with TotalBoat 5:1 High Performance Epoxy


We used a syringe to inject thickened epoxy into the deck/hull seam when the gap got small.



New adhesive to fasten Capn Jack's bow handle stainless repair plate to the deck, that was his fix to where a previous bow handle had torn off and left a hole in the bow. We added a strip of fiberglass cloth to act as a catch basin for a THIXO blob, that will fill and seal the hole. Just to confuse you I have the stainless plate turned around facing the wrong way.


Hmmmm, Float Test or fairing and sanding next? Maybe an air leak test...



Alan sent WAVE and PHOENIX some bow trim.


WAVE's peeking outside...
