Coaster 23 by Lovett/Chudley

I am looking for information on the Coaster 23 designed by Lovett/Chudley and built by RFC Marine of Sidney British Columbia. The Coaster is a trailerable mini trawler built in the late 70s early 80s. *She was to be powered by diesel 24-75 hp. *Some were powered by a Pathfinder diesel 50 hp engine. *Her underwater lines were very similar to a small Albin.

Thanking you in advance for any information that is provided.

Bob,
We had an Albin for 6 years. Great boat. Would like to see pics of the Coaster 23. Did you post on Boat Design?

Eric,


Thank you for the reply. *I am in the process of buying the Coaster. *Here is a picture of her, I hope.

Bob,
I've seen these boats,probably in BC. I probably thought they were Maple Bay boats in the past. And I see YOU were the one talking about the Coaster on B Design.
The boat in the pic looks like it is stern light. Not a good thing. Many Uniflites looked that way. Perhaps the designer established the cabin attitude and gunnel from the keel not taking into account the stern will float higher in the water. Not very smart for a marine architect I'd say. My friend here w the 31' Uniflite needs to get the boat op to 10 or 12 knots before the house is visually level. Thanks for the picture Bob.

RE: Coaster 23 by Lovett/Chudley

Eric,Thank you for your reply and observation. *May I ask how you came to your observation that the Coaster was light in the stern? *I do not see what you see. *The engine is in the dead centre and the tanks are placed properly. *Would this issue show up in marine survey? *Should I be worried about this issue as a possible future owner? *What are the consequences of a light stern as you have indicated that this would be a serious mistake of marine design? *I have attached a couple of pictures to see if you notice anything else.


Thank you for your expert observations. Cheers

Coaster 23 by Lovett/Chudley

Bob,
Boats that are very pointy (low prismatic coefficient) in the bow and wide and full at the stern (mine is thus) may have a very unbalanced state between their center of flotation and center of gravity if the center of gravity is centered and the center of floatation or lift is far aft. Seeing the Coaster out of water leads me to believe the center of flotation and weight are matched quite well. But in your 2nd post the rooftop and windows slant downwards as one goes fwd. This tells me the designer didn't know what the pitch attitude of the boat would be. Your boat, being an inboard means the engine must be about in the center of the boat or even fwd. The only way to trim the boat properly is to have a great deal of heavy gear aft. Fuel, water, batteries and such. Even if the designer is successful by moving other stuff aft the boat is not ideal as the ideal boat has most or all the heavy stuff centered in the boat. Not to worry though. It looks like you're boat is well balanced***** ..except the visual effect of the windows and roof. I would love to have a hull to convert to an outboard.
PS** That would be a perfect boat for a 55hp Yanmar 4JH.
The older Albins were nearly a displacement hull and the later ones had a hooked bottom aft so were quite speed limited.

RE: Coaster 23 by Lovett/Chudley

I'm curious about how one would best handle the anchor on such a boat, as equipped.* Bring up the anchor from the forward hatch?* Drop the anchor from the stern and walk the rode to the bow?

RE: Coaster 23 by Lovett/Chudley

Mark,
I've had some thoughts about anchoring from the stern on Willy. Anchoring from the bow has windage issues. Bow swings back and forth and when it's blow'in the bow flails back and forth jerking the rode hard trying to break out the anchor. Not good. Anchoring from the stern should render the boat much more stable in the wind**** ...like an arrow. If one draged onto the beach at least it would probably be bow first so you won't be jamming your prop and rudder first thing onto the beach. Stern cockpits are usually more secure. BUT one must keep the anchor rode out of the propeller. Shouldn't really be that much of a problem but one would need to be attentive.
As for Bob's beautiful boat that I was criticizing a day ago (I'm lusting over her now) I see no other choice but to have light ground tackle, keep it in a box, push or pull it up through the fwd hatch and deploy it conventionally. Alternatively one could lay the rode in a figure 8 over two posts (like FF does) and use an anchor like a Danforth or Fortress (for this boat the Fortress would be great since the bow won't carry much weight) but I think I'd anchor from the stern. Run the down the anchor until it hits bottom, ease fwd and pay out the rode as you would from the bow. I don't see how one could transfer the anchor line from one end to the other on this boat.

Eric and Mark,

Excellent discussion about anchoring. *The Coaster has a properly drained anchor locker in the bow. *It does not show up in the pictures. *She also has a bow roller that is not installed.
I have added a picture of the interior and of the Pathfinder engine for information.

Bob,
Still love the boat. That's a Beta* ..isn't it? They are really good Kabota engines. Keep the anchor and rode light. What's it's displacment? Guessing 5 or 6 Klbs. Are you going to the boat show w the group?

Eric---

The whole photo slants downward.* Here is the photo with the horizon corrected to level using Photoshop.* If you put the picture in Photoshop and run a level line across the horizon and then move it to the tops and bottoms of the window you will find that they are exactly parallel.

I'm not saying the boat is balanced or anything about the centers of weight in relationship to anything else.* Only that the boat is, in fact, floating level with regards to the windows.* The design itself makes it look a bit bow heavy but this is a factor of the lines, not the way the boat is actually floating.* The fact that the sheerline above and the rub strip below the dark stripe on the hull curve up a bit toward the stern adds to that illusion of bow-heaviness.

One could "tippy-toe" alongside the main cabin, holding onto the hand rail on the roof with one hand and holding the rode in the other,*but I'd not want to do it unless the water was calm.** Got PFD?

Bob, please install the bow roller with anchor.* We'll all sleep better.

But Willy is double-ended (no square stern), giving him greater anchoring options.* Most of us don't/won't have that advantage.* And neither do the Nordic Tugs.

The Coot's stern:

RE: Coaster 23 by Lovett/Chudley

Mark,
Why are you thinking stern anchoring would be more appropriate for Willy w her bath tub stern? Did you have anchoring w waves coming from aft in mind? That's the only condition I can think of that would give Willy an advantage. We can easily put bow rollers on the stern as we put them on the bow can we not? With your bigger boats you would need winches and chain locker infrastructure to do as you do on the bow on the stern. Some would think it just too radical and unconventional to even think about. For me it's gobs of fun to question things that haven't been questioned for decades or perhaps forever. Sometimes I learn why we do the things we do the way we do by doing or thinking about doing things another way. One thing I would not like about stern anchoring is that the wind would be fresh over the stern not shielded by the house and cabin structure fwd. On your coot Mark the little wavelets caused by a breeze would make a bit of noise under the stern**** ...unlike Willy. If I put the rudder on the bow of Willy and turned the prop around she would go quite well w her new fish form hull. How bout that Marin**** ..a "tractor" boat. For non-aviation boaters here a "tractor" aircraft has it's porp in the front "pulling" and a "pusher" has engine and prop aft. We boaters must be more conventional than fliers (judging from the preceding as tractor boats are almost unheard of) but pilots are one of the most conservative groups I've ever met so one can see where that leaves us boaters.

It seems to work for big tugs, although I'm not sure exactly what their running gear configuration is since I've never seen one out of the water.* Probably not too practical for small recreational boats the sizes of ours, though.......

Yes, I was thinking of waves.* A square transom is going to "take it in the chin."

Mark,
You mean slap and pound? Yea** ..not good. What's Nordic Tug got to do w this????
Marin,
You're right (98%) I think. I do think the angle of the camera shot to the boat could be a bit off and help w the illusion as well. Also the horizon on the right is much further away than the horizon on the left**** ...if we could see through the boat we'd see a jog in it.
But that's mostly fly stuff. Your'e right and the boat would benefit (visually) if it were all white.
The most awesome tug would have 2 counter rotating propellers at both ends.
Marin,
I went back to look and the horizon is WAY slanted. Can't believe I didn't see that!

Sorry, bad wording on my part.* I should have referred to the level of the water in the distance, not the actual horizon.* Moving a line parallel to the water "horizon"*down to the window line shows the window line and the surface of the*water are parallel.

Yea*** ..and it sounds like you consider that a sin. I can't find anything better and the search is getting tiresome*** ...not as fun as it was a month ago. I probably should just stand down. Last boat to lust over was a 50' Navy conversion like FFs.
