With the size my workshop will turn out to be, That is a very tempting idea😆 Part will be for the restoration of my Billings sea Queen, and part for my other hobby of model aircraft, I have a number of repair jobs due to the haulage company when we moved here to Portugal.
I found when fitting spray rails to use triangular stock like trailing edge section for aircraft wings. It looks neat and bends more easily than square stock.Fitted thin edge up the right angled face forming the deflecting face. Filled and sanded it blends well into the hull. Maybe not true scale but looks nice. It comes in many sizes and suppliers.SLEC is one for starters and Hobbies is another. Balsa Cabin another. Just loads if you use uncle Google.👍
The principle is simple. Fluid flowing over a surface tends to stick to it (Google Coanda Effect). It's worse at the low Reynolds numbers that models work at. The result is that water displaced by the boat at speed tends to flow up the sides of the hull, sticking to them, and can even pour onto the deck. This slows the boat down and can swamp it. If you have a sharp chine, you can force the water to move away from the hull at the discontinuity, because it can't easily flow around a sharp angle. Ideally, you can deflect it downwards and get some lift, helping the boat onto the plane. So a lot of models have small rails along the chine, shaped to deflect the water downwards a bit. This is what many of the Aerokits models have. Deep Vee design relies on these a lot - the bottom of the hull has a series of parallel spray rails so that as the boat rises in the water the spray is deflected downwards by each rail in turn and an ever-smaller part of the hull bottom is wetted - reducing drag a lot. But the Sea Queen is not a Deep Vee, and doesn't need more that the one set of rails along the chine. Deep Vee spray rails can also help to cushion the shock when a boat drops back into the water after leaving it - but that's more useful in full-size practice rather than models....
Titebond 3 is a high performance PVA. We can't get Titebond 3 here in South Africa. Gorilla/Gator glue you which is a polyurethane based glue have to Work using Rubber Gloves and have a bottle of rubbing Alcohol handy as it sticks like mad and you won't be able to get it off your hands. I still have Cascamite! Been using a Sika PVA adhesive but the bulwarks were fitted with ZAP 30 minute Epoxy. I have found an eight hour epoxy to fix the stringers to the bulkheads with with. Why is it we make short worktime adhesives is beyond me. I have always found that the quickset glues are prone to be brittle. The only one I haven't found to be brittle is ZAP. Going to epoxy the inside of the boat before fitting the skins
I have carried this exact kit with me for many years. Your blog is my inspiration to start :-) Scared to make a mistake as this is my first build. I bought a bottle of Titebond III a couple of years ago!
Roger.com, I am not so sure about being less detail on a Norfolk Broads Cruiser. I have a small 21ft fibre glass hulled boat in Potter Heigham on the Broads. But when you see the older wooden Broads Cruisers they have lots of detail especially the ones that get cared for as they should being wooden built. Some of them are so beautiful and well varnished polished brass, Chrome fittings and well groomed. If I could afford a wooden cruiser and be able to keep her in the fashion she should be kept then I would. But if I win the lottery then I will have one. Even the old wooden sailing yacht's are kept in wonderful condition and lots of detail brass etc.
If she is the 34" model then she's the Sea Commander, 46" is the Sea Queen. I have got both, picked them up from boot fairs, at least 4+ years ago, and sadly still awaiting refurb. I also have a 46" Crash Tender still waiting the same. As well as a 34" crash Tender I bought back in 1994 as a 50 years anniversary kit and a 46" I got at wings and wheels about 3 years ago both in boxes waiting a full build from new. I have also still got my early 1970's Sea Hornet that also needs a refurb. Amongst other new and second hand models to get sorted out. I always say one day I will get round to it.

"I wish I had never said anything or about Biro pretend deck planking Cheers Ian T" You weren't to know he was selling such crap! Are you sure it's the same guy you got yours from? I can't believe he was supplying first class drawings years ago and is now supplying rubbish. Why bother drawing (well trying to) around the frames etc. when you already have good drawings?
