Hi Guys Jamie had a crack on the port bow area as far as i can remember which happened while beating towards Lord Howe Island,he used foam cut in quite a large circular pattern and glassed that to both sides of the bow meaning port and starboard, thus strengthening up the forward area, my mrk 1 built by Formit did the same thing water leaking into the bilge from a crack up the front.
though the Top hat design is awesome, only the Mrk 0 and Mrk1 were really built to what a yacht should have been built to go out into blue water,
each Mark there after were built cheaper and cheaper, and if you don't believe me climb into a mark 3 into areas you have to crawl into and have a look at the shoddy workmanship thin ply with a splash of glass on it to hold it there, ply under your decks instead of solid glass and ply in the roof area and Bow area with a thin layer of glass, ask Shaun he didn't believe me until he did repairs on blue Moon, so the design is fantastic the build quality fell behind.
All bulkheads add strength in some way that front one i am guessing would help the deck area forward, i know i would want it there, as for stringers, even the humble endeavor 24 has stringers in the bow area making her a really strong boat while beating i was gob smacked when i bought my first Top hat and saw no stringers, if you bang on the bow area from the outside on the hard stand you can feel the weakness in that large area so i do agree with mark it is an area that needs to be looked at if you want peace of mind.
One boat that stands out as being a high class built from a production boat is the Brolga 33 you paid a lot of money for it but it was first rate build quality large beams glassed into the boat as always just my opinion
BE HAPPY 4 THIS MOMENT 4 THIS MOMENT IS YOUR LIFE.
