So happens I am replacing my cabin top rails on my 303...After breaking one...
They were leaking ( a nearby yard charged the PO a pretty penny to "fix" them several years ago. They lied to him) quite badly.
As per some other threads on here, I found that the "late model" -circa 80's- Pearsons have thru bolted handrails in the cabin top. After removing the bungs on the exterior ones, I found that the bolt head had been expoxied. And in trying to remove one, I split the stbd handrail along a wood seam ;(...
Well, thank god for D&R Marine!. They sell lots of Pearson OEM products, including the right sized handrails:

Just got two new ones from the yesterday, and they are exact matches.
Sooo...Now the mission is to NOT break one of these!
