Subject: Yes, similar on Murre

Hey Connor,

Yes, Murre had that exact problem. The design called for the support of the mizzen to be taken by the cross members, which were precious thin.

The support work on Murre was one of the first projects after I bought her and was before I knew much at all. I had it done by a local boatwright, so I can't tell you too much and I've never documented it.

But go here (http://www.marineryachts.com/projects/murre/cockpit/Cockpit%20Footwell%20Rebuild.htm) and look at photo 004 and photo 010 to see some general shots of Murre's solution.

Essentially on starboard I had installed a 2 x 4 sized post made of a hardwood that runs from the deck cross members down into the hull (along the cockpit side, which adds to its strength). On the hull the boatwright built a box to sit on the curvature of the hull (not pictured) that created a flat surface for the support to seat into. The box if filled with resin and so creates a nice anchor for the support.

On port even I am confused. I think the boatwright built out from the cockpit and tied into the existing structure that holds the ice box. That's what the picture suggests. ???

Again, this was the first job I had done…back in the day when I still thought a deck of plywood covered in glass and a fiberglass deck were the same thing.

I know Bruce on Gitana Vela did this work in a different and very successful way. If I recall he added a much reinforced cross member over the engine for the vertical support to tie into. ???

Sorry I can't be better help here. This is one of those jobs that's a bummer to contemplate, but once you're done you'll have the luxury of forgetting that part of the boat altogether.

Best,

RR

...on your crossing from California to New Zealand. That's really something!

Given the age of our boats and their imperfect build, I'm always amazed at how many are out braving the ocean with an ease equal to many that are bigger, newer, more expensive, more comfortable, yet somehow no more capable than ours.

Did you pass through the Tuamotus? Fiji? Samoa?

I was heatbroken to turn north at Bora Bora (when I wasn't scared out of my goard, that is), and even now I would have loved to continue west, to see more of the tropical south pacific, fabled New Zealand first penciled in fully by Cook.

But I also feel fortunate to have seen so much of the deep ocean, north and south. To see the ocean on its own terms. And to have made Alaska...

Fair winds,

RR

[> [> Thanks Randall -- Connor, - Tuesday - 01/15/13 - 11:59pm

Thanks for the tips, Randall. I'd seen those picture before but, as you mention, there is a bit that is not made clear in the photographs. Your description is quite helpful. I'm having the masts pulled tomorrow and will start to gut the cockpit decking and figure out the best way to go about it. I'll certainly document it thoroughly and post it here for future reference.

One thing I was a bit surprised to hear is that your shipwright supported the deck on the hull. I've always tried to avoid points of contact on the hull when possible, but it does seem feasible on a spot filled with resin. I'll certainly make that a consideration.

I too am proud to see Mariners crossing oceans. In an age where most boat builders don't bother with anything less than forty feet, it's good to know that there still exists a contingent that sees fit to head to sea in small boats. As for all those things like comfort... well, ignorance is bliss- Ardea remains the most comfortable boat I've ever taken offshore. In any case, she did damned well and carried on with indifference.

I traveled along a pretty typical Coconut Run. CA-Mexico-Marquesas-Tuamotus-Societies-Cooks-Niue-Tonga-NZ. I had a couple of buddies on as crew until Tahiti or so and then single-handed from there. I wrote extensively on www.svardea.com and will continue to do so as I peruse the wonderful coast and islands of NZ. To be sure, your musings from aboard Murre were an inspiration back when I spent my days in a lowly cubicle and my nights toiling away on my boat.

I'll post to the forum with some photos and whatever solution I come up with soon!

Cheers,

Connor
