New Sunfish owner with boat needing repairs & ID the year

I have a yet to be determined year Sunfish. I believe it to be pre 1970 and the cockpit has separated from the deck. I have extensive experience with fiberglass repair (and work at a large adhesive company). My plan is to grind away the gel coat and butter it up with epoxy then lay multiple layers of glass cloth. Then I will apply new yellow gel coat to the entire cockpit. How do I ID the year? No plate on the deck behind the splash rail. No numbers on the transom. Bronze hardware holding rudder. No storage compartment.
I am very excited to get this thing on the lake and have some fun.
Thank you11A2B7B9-11E5-4838-9876-6972205AAA0D.jpeg

From what I can see I think your boat is between 1965 (when front deck stripe was added as an option) and 1968. Halyard block would be another clue but what the heck is going on with the top of that mast?

You have a old boat that looks in good condition. I would not but the time, effort or cost in. Just sail it.

I think it’s a 69 or 70. I’m pretty sure that the bow stripes were introduced in 69 (or maybe 68). Also, looks like you need a bridle and bow handle.

Breezebender, I’ve seen a lot of brochures, and haven’t seen any mention of optional stripe. This shows red and blue stripes in 65 with an otherwise pure white boat http://www.sunfishklasse.nl/documenten/Sunfish Timeline.pdf and mentions an optional sail, but not an optional deck stripe. I am very interested in keeping my Sunfish knowledge up to date so would like to see any old brochures mentioning stripes. There is one from 69 I have seen mentioning stripes and I should see if it could be added to the timeline. OK, enough of my sidebar!

Looks like it is missing the cap on the mast and someone set up a Jens to accommodate…?

Wow you guys are sharp. The top of the mast is missing the plug. Being that it has an AMF Alcort sticker it must be a 69 or 70. I will be bonding the deck to the compartment

Hi Beldar,
You are right, the sail stripe is the option, but it would match the existing deck stripe, no?
That timeline link shows this for 1965:
• White sail with diagonal stripes at peak to match deck striping offered as an option.

Am I reading this wrong? Forward stripe had to be there in 65, if not earlier?

That doc shows an all white boat with red bow stripes, and an all white boat with blue bow stripes. It doesn’t mention boat stripes being an option for the other colors, including the white boats that have colored spray rails and cockpits. I think the old all white sail with the narrow red and blue stripes was the option for those nearly all-white boats with the red or blue stripes.

Beldar, the timeline might need to be update. I have an AMF 85 and I know for a fact that it has aluminum backing plates. The timeline says this didn't happen until 86 when Loveless took over.

If the deck is not connected to the cockpit, and you capsize, all that water is going right into the hull itself! That problem must be fixed.
I noticed this in my Sunfish purchase as well. It looks very similar to the OP.

It seems fairly leak free, but when I capsize, the hull fills up with tons of water. I did an air test and noticed a lot of air coming from all the gaps where the cockpit meets the hull.

Any advice on how to seal this ?

A friend in the business recommends biaxial tape for maximum strength.

Where in MI are you located?

This problem seems like the perfect use for 3M 5200 sealant. It is silicone-like but tenacious and virtually permanent. I’d clean the whole area, then wipe with acetone, then apply the 5200.

This is from 3M’s description: 3M™ Marine Adhesive Sealant 5200 is a one-component, high-strength, moisture-curing, gap-filling polyurethane for permanent bonding of wood, gelcoat and fiberglass. It cures to form a firm, rubbery, waterproof seal on joints and boat hardware, above and below the waterline. This product has been trusted throughout the marine industry for over 50 years.

Update. I repaired the delamination of the cockpit to the deck. I work at an adhesive/chemical company so I have all the needed materials at my disposal. many parts have been ordered. Next to do is deep penetration epoxy coatings on the dagger board and the rudder. I hung the sailboat upside down so I could see inside the repair area. Layed up 3-4 layers of glass cloth to the cockpit and deck mating surface.
