  1. Good job! Looks like you really strengthened that transom.

    I did wonder why the transom in its original condition would be a problem. Is there a performance issue with the transom not flat?

  2. Absolutely a problem with the scuppers or drain plug or stress cracks. Over time if they leak, even the slightest, water invades the inside of the transom and never leaves or dries, a set up for eventual wood rot. Ya wanna prevent that, service the scuppers or drain plug(s) or stress cracks with a silicone…immediately when it first happens. This is a five minute job, look at the trouble and expense you save yourself with a bit of attention to this detail. Water is the enemy.

  3. Great instruction video and a nice job, I am a strong supporter of West System, the trick with the plastic bags I will copy, mostly work on smaller boats that at times we go from the inside out.

  4. Noticed some plywood end grain in the bottom of the the transom before fitting the panels. Did you grind all the way to the bottom fiberglass of the hull just leaving the plywood imprint or was wood still there? If the wood was there, did you treat it with penetrating epoxy before the build-out?

  5. As a novice boat restoration devotee, a Hallberg-Rassy 35 Rasmuss I t’s critical to view the the experienced work of others to understand both techniques and tools necessary to competantly attempt related projects on a piecemeal basis. Many thanks

  6. Great work. You are a master with a very large belt sander! How did the transom get so far out of plum? Previous repair or manufacturer?
