A Platform To Stand On

Metal fabrication is not a frequent topic here because of the specialized skills and tools it requires.  Nevertheless, good communication skills can substitute for those, as Ken of s/v Painkiller demonstrates:
Not too long ago on the Pearson 424 forum that I hang out, someone asked if there was any information or drawings, or possible "who" fabricated the anchor platform that was offered to Pearson owners when having a new boat built.

Nobody had any concrete answers, so I offered to the gentlemen inquiring that I would give him an accurate detailed drawing that he could have the exact piece reproduced from any competent fabricating shop.

All I had to do was go forward with measuring tape, paper and and pencil. I noted in my drawings (I shared with the forum) that I would add a third or fourth point to stiffen the platform as it seemed to me it having a weak spot with potential heavy loads from getting a stuck anchor off the bottom. Not to mention that mine was bent at least 5 degrees....I never noticed it till I starting measuring for the drawings.

I had some ideas and traded some unwanted stuff at Sailors Exchange in St Augustine, FL for some various bits and pieces of stainless steel hardware that I could fabricate into something to help beef up the platform. A 1/2" U-Bolt was my starting point. The actual finished bracing point saw a few different ways before I settled on a robust 3/8" plate that supports the brace for the anchor platform and offers me a point near the waterline to lead a snubber line for anchoring. After coming up with a definitive plan, I removed the platform and brought it to a local shop to have straightened and weld up my various pieces.

I backed it all up with 12" x 5" shaped block epoxied into the forward stem. Not sure if I would tow my boat at sea in an emergency from this point, but for sure at anchor it will be fine.

I'm thinking this will take a load off my concerns of have an oversize anchor bury itself a little deep and need some persuasion to pop it free.
