Looks bow down but not seriously so but the water line grove should keep the situation honest. Looks a lot like a GB but I think by your'e pics less deadrise.

Amazing that there are tabs on her. And her props are in close to the keel. Would be a good boat to run single w a twin .. if there is such a thing.

Hauled the boat and put her into the shop yesterday. Some quick measurements today showed that there is only about 4" of drag to the straight section of the keel. The rudder seems a little small at slightly under 5 sq. ft.

I agree with Eric that it is far better to remove weight to fix the trim than to add ballast. I removed the genset today -- I hate the things anyway! It is pretty well forward, and about 600 lb. That should help, but I suspect I'll still need ballast. Even with the genset, the boat was pretty light -- there are two molded in waterlines, and she was floating well above the lower one.

If I weren't so lazy, I'd do a moment-to-trim calculation and know for sure what will be required. But I like the barrel idea as it gives you a chance to experiment with the steering.

All boats squat by the stern and dig themselves a hole as they approach hull speed. That is one way of understanding what hull speed is -- the boat digs itself a hole and tries to climb out.

Doug H,
OK good .. The gen set extraction sounds good.
Is there any space in the Laz for tanks that are further fwd?
Five square foot rudder? Sounds small. I think my 30' Willard rudder is bigger. A bigger rudder may be some useful ballast. You can buy ready made rudders (Buck Anglequin sp?) or have one fabed to your specs. Some of the guys here know the ratios of area ahead and behind the shaft.

Since you've started this trim/ballast I've been thinking about my own boat and from my slightly foggy memory observing the WL grove I think she is high in the bow. I don't see any significant downside to some extra weight aft. I have almost 100% nylon line rode and probably extra ballast in the Laz. That's probably why I have a significant sailing problem at anchor. She may be a bit easier to handle in the harbor w the bow down a bit .. or more propperly the stern up some. I know what about 16 guys are going to say about this but I've never been one to duck a tomato.

Re the drums aft w water in them .... easy way to make a big ballast change but evaluating the stern sea issue they would need to be very well secured. Probably tied or chained close to the middle of the barrel to reduce the chance of them tipping over. Over 400lbs each.

By the way you aren't Doug Henning are you? I'm a Henning but no relation to Doug.

Ballast on Defever

I had a boat similar to yours. It was a Hardin 39 which I am sure was a Defever Knock-off via Taiwan. Single Perkins T6-354. I had it for over 20 years and it was good to me. It came with approx. 1000# of lead pigs of ballast in the lazzarette.(sp?) I would move the ballast around occasionally to trim the boat.(Dinghy aboard/or not, etc.) With full water tanks the boat was on her lines.
I also increased the size of the rudder by a factor of two by adding to the trailing edge; the leading edge; and filling the space between the top of the rudder and the hull. I also added fish-tails to the trailing edge. I was able to back down, without backing and filling, and the boat would steer without power being needed. Downwind in a following sea was my favorite.
I regret to this day selling this boat. I now have a Carver 350 Voyager, a nice boat, but no comparison...even though it has twins(!!!)

Ian, thanks for that feedback. I am also thinking of a rudder make-over: enlargement, fishtail and possibly lower end plate. Hoping to use cement blocks (lead too pricey) placed out at the chines to try to slow the roll a bit. This boat is so wide and light, and with hard chines the roll is a bit snappy for my taste. Trouble is, if I make both changes at the same time, and the steering improves, I won't know which change had the biggest effect.

Eric -- not a Henning but a Hylan. I'm on the oposite side of the country from you, eastern Maine. Love the looks of your boat -- if I can make the DeFever look half as good, I'll post a picture. Fixing the trim is the first step, then a creative color scheme. I've had some luck in the past making homely boats look pretty good by just changing the color scheme.

Hello Doug H,
I didn't mean to hijack your thread but as a new to me boat I'm trying to learn as much about it as possible.
We will be back out your way in May or so, maybe we'll meet up somewhere. Stay warm up there.
Rob

Hi Rob, No hijacking in my opinion - in fact, some very helpful comments. I'm interested in all things DeFever.

I noticed that you have a Maine presence -- hoping we can get together next summer, providing I survive the winter!

Doug H.
