1969 Chris Craft Roamer 46 refit

Preparation is everything...or so they tell me.

I'm still working toward splashing this month. Getting exterior holes sealed up is my current priority. I filled a whole bunch of them by installing the stanchion bases, fairleads, and fresh water fill on the mahogany toe rail. I had all of those original bronze pieces rechromed and sitting in a box since 2016. It's nice to finally have them back where they belong.

I buttoned up four more holes on the cabin top by installing the chromed bronze mast base. That has the practical effect of getting the boat closer to weather-tight, and it's pretty, too. It's also nice to finally move stuff that's been taking up space in storage back to the boat, where it belongs.

Next, I started working on closing up holes in the engine room; in this case, the raw water inlet for the air conditioners. By "closing up," I mean getting the raw water pump installed so I can connect the strainer/seacock to the pump with a hose. I had a big 3000gph Dometic pump that I was going to use, but after looking over the spec sheets for the AC units, I realized I only need 1000gph. The electric requirement drops from 6 amps for the Dometic unit to 1 amp for a March 1000gph pump.


Anyway, I finally got the platform built for the pump and distribution manifold, and got it installed. The distribution manifold is made of Schedule 80 PVC Tees, close nipples, and hose barbs, and is attached to the pump platform with some 316 stainless pipe straps I whipped up from stainless leftovers I had laying around.

Your welds are looking better and better.

Ha! I'm also making fewer trips to the grinder to clean up the tungsten after sticking it into the puddle. lol

The pros recommend NOT grinding a bunch of tungstens in advance, so it forces you to stop, leave the table, grind the tungsten, then return and get set up again before you can continue. It's basically a 'learn through punishment' model, where you intentionally inflict a punishment for each individual offence, and the natural tendency toward punishment avoidance induces you to not do the behavior that brings on the punishment. Which in this case is sticking the tungsten in the puddle or contaminating it with the filler rod when you dab.

Seems like a lot of learning is through punishment, either by yourself or someone else.

Well, the boat's not splashing in October.

I don't post articles to my blog (or link to them here) in real-time, so the boat's actually a lot farther along than what I've shared publicly so far. But problems keep popping up that take time to resolve, which I'll write about in the future, and they've killed my grand plan for an October 2022 launch. But I haven't given up hope and am now aiming for November.

Anyway, I installed the aft stateroom air conditioner. It was nice to finally get it out of my garage, where it's been sitting since 2018, and in its new home inside the boat. That allows me to connect a raw water hose to it from the pump and manifold I wrote about recently, and another hose from the AC unit to the thru-hull that takes it off the boat.

There are six raw water circuits in total that I want completed before the boat splashes: two main engines, one genset, and the three AC units. So that's one raw water circuit down, five to go.

Problems keep popping up that are delaying splashing the boat. I'm dealing with those as fast as I can, and fortunately the weather is cooperating. But I'm also checking off items on my pre-splash honey-do list.

I want to have all of the raw water circuits finished before I splash. Raw water circuits involve inlets for the water the boat is floating in, some sort of mechanism that needs raw water, and the outlet for the raw water after it passes through the mechanism. On this boat, that’s two main propulsion engines, one generator, air conditioners, and two toilets. I want all of the raw water circuits done before I splash the boat, because failures in raw water circuits are the main reason why boats sink.

This time, I got the salon air conditioner installed, including running new Shields 200 Series 5/8" hose from the raw water manifold I made recently to the aft stateroom and salon AC units. The installation went well, and I'm moving onto other things. Hopefully, the boat will be splashed this month.

Everything looks great as usual. I would put a pan under the A/C unit to catch condensation. It may be hard to drain though. Even on my separate evaporation units that come with built in drain pans , I make a separate pan out of fiberglass sheet and drain it separately.

[q240z]

Thanks!

Flagship Marine AC units come with built-in condensate pans. I wrote about that in the linked blog article. They also use modern compressors (scroll, IIRC) that get warm when operating, and insulation on tubing and other parts that get cold, so condensation on other parts of the system simply doesn't happen like it would on the old OEM piston compressors. The evaporator is the only thing that gets condensation, and it's got the OEM pan under it. I don't think another pan would serve any purpose.
