I see where that is a 1972 and it has the box stringers,when did Seacraft go from the 4 smaller stringers to the 2 box stringers? I thought it was 1973. And does one type have an advantage over the other.I have a 74' and a 72 and am just curious.

this is my first project, and have very little knowledge. I really know nothing about the foam stringers, whether good or bad. I just found the boat on craigslist, looked at it for a few weeks and scratched my head got some ideas from this site and some friends and started tearing it apart.

thanks hermit, hopefully ill have some more pics up in a couple weeks. still waiting on a fuel tank before i can get the floor done and i need to figure out how i am going to get the gunnel cap across town to the shop where im getting the work done. was thinking about calling a toe company and getting a roll off over here and puting on that and strapping it down

Depending on your trailer, you might able to screw plywood sheets to the bunks and transport it on there?

Nice work, Dan!

That's what I thought too - have never seen a '72 with the box stringers. Does the boat have a HIN engraved in transom at top outer area on stbd side? If so, it's a '73 because they weren't required in 72. Of course if the transom was previously replaced from outside, they might have removed the HIN. Boat has obviously been apart before because those longitudinal ribs on hull sides were not OEM.

I personally think the 4 smaller stringers would provide more uniform stiffness to the bottom of the hull. They would also create a stiffer "I-beam" when deck is bonded to top of stringers because you'd end up with twice as many vertical ribs in the beam. The box stringers probably require less glass and resin, so I'm pretty sure they were a cost savings. However the basic layup in all the Moesly and Potter boats is so stout compared to the average boat that either stringer configuration is way more than adequate!

ya when i got the boat the top half of transom was replaced and they cut off top 2/3 of the skin and left the bottom 1/3 of the rotted transom so there is no hin but my title says 72'

ya i was thinking about that, but i think the easiest thing is to spend a couple bucks and get a roll off over here.
