Any advice on folding props? Pura Vida is a 1974 MKII with a Yanmar 2GMF. When the boat was purchased a year ago she had what I suspected to be the OEM prop designed for the Atomic Four. The boat moved pretty well with this prop but seemed to hit hull speed and squat pretty quickly. Recently the yard replaced everything from the transmission back and now I have a nice three bladed parachute dragging under the boat. She powers better, but 1/2 a knot is 1/2 a knot. Obviously some math needs to be done to fit the right pitch to the boat/engine combination so what I'm hoping for is comments on brand performance from those of you who are using folding props now. One other thought, if any one has determined when to stop spending money on these boats please let me know <img src="emoticons/icon_wink.gif">.

In Apology. In not too many days our friends on the Great Lakes will be enjoying beautiful sailing weather and those of us to the south will be hiding from a sun that will strip the hide off of one's back. What goes around, comes around. If it is any comfort, by mid-summer most of the boats on Galveston Bay will have a stronger tie to the dock with their shore power cable than with their docklines. What is the old song about mad dogs and the noon day sun? Some here may not admit it, and it may be poor consolation, but by July your weather will be looking pretty good to us.
All the best!

When I purchased Pura Vida I found her residing in the portion of the marina with larger slips and 50 amp shore power. The previous owner had kept the same slip through several boats. When I moved her to another pier I learned that the 50 amp plug he had fitted to the end of the 20 amp cable would not fit the 30 amp outlet at my new slip. To compound the problem it looks like the original 110 wiring was still in the boat. At that point I removed the Carry On AC (which is a pain anyway), replaced the batteries with 2 group 27s and added a 50w solar panel and charge controller. The system works really well. The batteries are always charged even in the winter. The downside is sleeping on the boat at the dock can be a little warm so I sometimes hook up the shore power and put a box fan in the forward hatch (much easier to handle than the Carry On) for the evening. One of the two big bonuses is getting my slip bill and seeing the electricity at $.02 for the month. I should pay for the batteries and solar panel in about 15 years or so. <IMG src="http://www.cc27association.com/f3/toast/emoticons/icon_wink.gif"> More important is knowing that my zinks may last at least a little longer. From all I have been told we are in a 'hot' marina so not being hooked to the grid day in and day out at least slows the electrolysis down. When I had the PSS shaft seal installed the old prop was ruined by electrolysis.

I returned early and managed to get to the boat on Sunday. Wow I thought I would never see that boat with snow on it! The live-aboards claimed that the fairways were frozen over but somehow I'm a skeptic on that issue. I know this 'big deal' about a little snow sounds silly to those of you who keep a boat closer to C&C's home waters but the temp right now is 73, much closer to a normal Christmas day high. Warren, I'll be back around the 22nd. We can look at the ladder then.

Will do Warren. We're headed to Dallas then Costa Rica so I'll look for you in a few weeks.
To the Fleet,
Happy Holidays and Feliz Navidad from the Gulf.

Thanks Clare and David, Originally I was looking at the Mystic Stainless Foldaway that mounted to the toe rail. That would allow me to use the existing boarding area on my starboard side. But I do single hand and need to rebuild the stern rail anyway. Maybe build a gate into stern rail filled by the ladder in the up position?

Has anyone found a solution that they particularly like for a permanent boarding ladder on the 27?

I once owned a Catalina with Marelon thruhulls and never had a moments problem with them. When purchasing the boat the surveyor I use said they are not an issue for concern. Mike M

I just had a PSS Shaft Seal installed on my 1974 27 (along with a new shaft, the old one being scarred from the neglect of a previous owner.) So far it is working as advertised. Pura Vida has been converted to a Yanmar 2GM and the clearance between the end of the coupler and the shaft seal is under 1". I'm not sure if the Yanmar is longer or shorter than the original Atomic four. So far so good.

The recent post about the Halifax to Ireland voyage and reading the story on 'Crossing the Gulf' channel in the '27 Tales' section started me in a Google search for offshore stories in the 27. There was not much to be found. I would be interested to hear from other owners regarding what they feel are passages of note.
Thanks

Charles,
Some thoughts you may want to consider. As David pointed out teailering the boat can be done but the economics of it may be prohibitive. Does Florida require a permit for trailering a boat over 9 feet beam? Launching and stepping the mast will most likely require equipment that only a yard will have and add cost. Before buying Pura Vida I looked into trucking a Tartan 27 from Lake Texhoma to Galveston and the best deal I could find was about $800 decomissioned and recomissioned with a bonded hauler. I'm not sure what trailers cost in Florida but you may be able hire several moves for the price and the hassle of doing it yourself.
Your situation may be different but I am rebuilding my boat at the slip for the most part. But then I'm only 45 minutes door to hatchboards. Best of luck.

Pura Vida is a 1974 MK II and the boom also rotates. This is not the roller furling boom like found on Warren's boat, which is very robust. The boom extrusion is a 4" by 21/4" oval and that is roughly the same size as the boom on a Catalina 25 I once owned. The boom on the Catalina would rotate also. I looked at a MK III on my dock and it seems to have the same boom that my MK II has but the forward mounted traveler would prevent rotation. I could not find any way of locking the boom on Pura Vida so I suspect that some play was planned, possibly to reduce the wear on the sail. You may want to try South Shore in the links section.

Guillermo,
I have a Yanmar 2GMF which was surveyed about a month ago and found sound. It has a big knock when it first starts but doesn't smoke at all. The manual says that the smoke may be caused by bad fuel. It also moves around quite a bit compared to a new car motor but that is certainly a bad comparison. This may not be the answer you want to hear but I would suggest finding a marine diesel mechanic to come by and survey the engine.
Good luck!

Thanks for the information. The article in GOB was very useful, especially the link to the Harken site on loads. I'm going to keep looking at boats and getting ideas. I'm always ready to shamlessly 'borrow' a good idea when I see one. Warren, I'm looking forward to seeing your boat.

Hello All,
I just purchased a 1974 27 Mark II as a project boat and am beginning to refit her. My initial thought is to move the traveler forward. Since there is no recessed space in the bridge deck, like may be found on later models, I'm thinking of just placing it between the seats directly behind the bridge deck. This will solve a lot of issues with the bimini which is pretty essential down here and be a real shin banger too. Has anyone experimented with this modfication? Also has any one installed opening ports on their boat? I need some words of experience before cutting bigger holes in the cabin.
Thanks,
Mike on Galveston Bay
