Selway Fisher Clyde 18

[biglad]

I have built a couple of boats before, a Selway Fisher Highlander 11 and a 7 strake Caledonia Yawl. I took the notion to build another boat - this time a simple motorboat. Something that can be built in my garage, towed easily so I can winter the boat at home. I want to be able to take 4 for day sails with the odd overnight for 2. It had to have shelter from the rain and a self draining cockpit. I have no desire for huge speed (or fuel bills!) so motoring with an outboard in the 25-40hp range.

I looked at lots of designs, but none ticked all of the boxes, although there is some lovely designs out there. I spoke to Paul Fisher about what I was looking for and he came up with the Clyde 18. https://www.selway-fisher.com/Mc1620.htm#CLYDE

I started in April, and have got the strongback made up, frames cut out, timbers added and the central spine glued up. I've got photos on my phone - I just need to work out the best way to put them up here. I'll keep posting photos as I make progress.

Has self draining cockpit and overnight shelter, works for me! How to attach plywood to plywood frames? Wood frames will hold screws/nails well.....plywood frame maybe not so much ...??

[Oldad]

plywood to plywood" tape and epoxy, easy peasy and strong like bull....

[biglad]

Each frame has 100x35mm timbers half checked around the perimeter, apart from the transom which is 100x50mm.

I dont plan on using many screws, the CY I built had no screws or bolts and held fine. I'm of the belief that a few screws won't hold a badly glued joint, though I know that's a hotly debated topic!

Paul has drawn the plans for either lots of epoxy and less woodwork, or less epoxy and a bit more woodwork. I've chosen the latter...

I remember the last build and it worked out well.If anybody understands the concept of stress and applies it to epoxy joints with adequate bonding area,screws are definitely second best.

The framing is Douglas fir. I've cut the frames so the join on the frames that need 2 sheets is on the centreline. I've added a ply doubler underneath the pile of weights!

The outboard beam is a 175mmx50mm lump of iroko. The central spine runs up to the top of the beam, and I'll epoxy some more iroko below the beam, either side of the girder. This will take the lower bolts of the outboard.

On the transom I've cut the notches for the intermediate floor stringers. The ply transom (2x12mm) doesn't have the notches so that these stringers sit nice and flush. I'm planking using single 9mm. Without these stringers the plans show 2x6mm, but I'd rather do more woodwork than epoxy!

I've got the frames up on the strongback. Next up is to slot the central girder in place and then attach the transom.20210604_202003.jpg

That looks like great fun. A local friend is contemplating a Redwing 18, so I will point out this thread to him. Lots more room.

[biglad]

I think she'll be quitea decent sized boat, for the length she actually is. I asked Paul to draw her as wide as sensible, for towing width and handling. I also asked for sensibly sized side decks, I dont want to be walking a tightrope every time I go forward to drop the anchor etc.

[biglad]

Managed to get the spine in place. It lined up nicely with the frames.20210607_170639.jpg

Looking Great! Sweet Little boat!

Bump
What's happening?

[biglad]

I've been making a bit of progress. I've got the transom up and epoxied to the central girder. I had to do this in on the boat because I dont have the headroom above the workshop door frame to do it in one. I've made a separate frame because it is a heavy part- 2x12mm ply, framed in 4"×2" around the perimeter plus a 7"×2" athwartships outboard beam. I've added pads immediately below the outboard beam, either side of the spine to make sure there's enough timber to get the outboard mounting bolts in.

I've roughed out the timbers either side of the spine to follow the line of the frames. I've cut the bevels for the chine stringers. I'm now cutting the slots for the intermediate stringers for the bottom panel. You can maybe just see the first one on the frame immediately in front of the transom in the picture. There's a fair bit of twist towards the bow so I'll have to build a simple steam box to get the stringers to take the shape. The timbers make a nasty creak when I try to get them round the frames.20210629_183322.jpg

[biglad]

Comparing the two photos it doesn't look like I've put as many hours into it as I have!

[biglad]

A little bit more work tonight, slots cut for the intermediate stringers. Some need a bit of fine tuning but it's coming on20210701_212113.jpg.

[Oldad]

Glad to see you are making progress. I am very interested in this design.

[biglad]

It's all going pretty well. This weekend I'll get the slots for these stringers cut for the other side, and finish off the bevelling off the stem etc. I've ordered some 1000 gauge plastic layflat so I can steam bend these stringers over frame B before I cut the slots.

[biglad]

I've got the stem (apart from the last few inches as the boat is hard to a wall- when I move the boat I'll finish it) and frames bevelled for the stringers and planks. I used the layflat tube and wallpaper steamer to bend the intermediate stringers. They're not in their final place but the twist they've taken will be fine, I'm sure.20210705_201317.jpg

[biglad]

I've got these intermediate stringers glued up on the starboard side. The port side I still need to cut the sections towards the bow. One more evening steaming and 2 nights epoxy work will see them complete. Once this is complete I'll steam and epoxy the chine stringers on. They are 2 thicknesses of 20x75mm and the slots are cut to take them.

I'm quite tight for space so I'm going to put the bottom planks on before the inwales. This will let me get inside the boat and tidy the epoxy up with one less obstacle to trip over.

[biglad]

I've got the forward sections of the chine stringers dry fitted. The boil in the bag method of steaming them worked quite well.20210719_210038.jpg

[biglad]

I'll remember to take pictures in landscape before posting next time!

[biglad]

I made a bit of progress tonight- the inner laminates of the chine stringers are glued on. A couple of temporary screws at each frame and at the bow, to hold the stringer in place while the epoxy cures, held it no problem.

Next job is to steam the outer laminates. This will be much easier- I've got the inner laminates I can clamp them to, to get them in the proper shape. Then once the stringers are on and bevelled, it's time for planking!20210723_213702.jpg

[biglad]

Thats the frame work all glued up for the bottom planks to go on. I'm leaving putting the inwales on until the lower planks are on, I'm a bit short of space and need the room to get underneath the hull.

Next job is to get busy 20210730_100947.jpgwith the saw, plane, chisels and sandpaper and get the frame ready to take the lower planks.

Gonna be one sturdy little boat.

[biglad]

Made a bit of progress over the evenings this week. Got the chine stringers bevelled to take the bottom planks. I spent hours sanding the framework. From past experience it's best to do as much preparation as you can before fitting planks etc- much easier to do while it's open.

I've got the aft section dry screwed ro the frame and the forward section screwed and lightly clamped to get it to allow the weight of the sheet to help it start to take the bend. I don't think it'll be too much trouble to get it down to the frames.

If I get a chance tomorrow I'll glue the aft section of the plank in place.

I've got the aft sections of both sides of the bottom planks epoxied to the framework. It was a bit of a challenge getting everything glued up and planks on before the epoxy goes off. Next job is to trim off the excess of these planks (I've started to do one side as you can see in the photo) and then fit the forward sections.20210810_203025.jpg

[biglad]

I've been plodding away with the boat. The bottom planks are on and glued. I've trimmed off all excess and planed the bevels and cut out for the upper planks. The flat is planed for the skeg and stem. I've cut the slots for the inwales, but haven't yet fitted them.

The twist towards the bow wasn't too bad to get the planks on. I poured boiling water onto towels on both sides of the plank and left it for a while. Dry fitted it and held it with some screws and large washers for a few days and then glued them. Wasn't any problem.20210824_203502.jpg20210824_203449.jpg

That was a good idea with the boiling water. I would have been listening for the horrible CRACK! sound just when I thought I'd had twisted into place.

[Oldad]

Great to see your progress. Looking good.

[biglad]

Progress on the boat has been a bit slow over the last couple of weeks- been busy doing some home DIY! I'm back to it now, and I've got the inwales glued on. A quick clean up once the epoxy sets and I'll get going with the planking. Going to start at the bow, and spile the shape on the plank. It'll be easier starting where the shape matters, because towards the transom I fit them oversize and trim them when the glue has set20210909_222008.jpg20210826_205130.jpg20210826_205059.jpg
