Almost all of the single pack polyurethane paints will do a fine job, including all the yacht enamels. I wouldn't use weathershield, but thats me. If she needs her hull doing every couple of years, it might be OK and of course cheaper. I would also look around the boatjumbles for paint, often found surplus to somebodies requirements.
polyeurethane gloss. it's all in the prep but iv'e used dulux for years without problems. i also use leyland paints which are a bit better but more costly. the most important bit is the primer/filler don't scrimp here, buy the best quality exterior primer you can get. i can recomend leyland paints as i heve used them for inside and outside paintwork, especially where i'm looing for a good finish.
It has often been said, but it is still true that the three most significant factors to getting a good finish are preparation, preparation and preparation. As long as that is good, I think that whatever you use will be fine. Like Mirelle, I have a preference for alkyd paint rather than PU, but that does not mean that everyone else has to follow my preferences.

I've come across a paint in Spain, Titan make, which is both PU and Alkyd, haven't tried it, but I wonder of it's the best of both worlds? Might be worth buying some for my Wheelhouse roof and testing it.
Ditto. I feel that polyurethanes are too stiff/hard for a timber hull, so I laways use enamels. I guess it does depend a bit on you planking timber and whether it is epoxy sealed though.
Single pack polys are not as hard as the two pack variety. Also I see normally caulked boats, crack enamel in one seasoon anyway. My old one used to anyway.

I use two pack polys on my wooden boat, but she is carvel and splined, my brother does the same, his is double diagonal. Which means, we only have to paint the hull evry ten years or so. Lucky eh? Pity it's this year and the paint (perfection 709) isn't cheap, but it is good!
It can't be! The basic resin for the paint is EITHER Polyurethane OR Alkyd - it can't be both. They used to make paints which were basically Alkyd resin with polyurethane additive for "toughness" or something, but were still basically Alkyd paints.
It could be that the paint you have seen is actually the WORST of both worlds.
Yes, but Blakes keep changing their paint, for the worse in my opinion. I have used their standard undercoat for years, and got on very well with it, but they have now brought out "Yacht primer and undercoat" which is awful. I can't get it to brush out at all, it leaves tramlines and, to cap it all, it doesn't cover very well. After three coats of white, the grey wood primer is still showing through quite clearly. And that is after two weeks to dry out.
I will be using Awlcraft single pack on my Hull as I had already purchased it before being made aware of the debate of marine versus regular enamels. Dulux weathershield is an acrylic latex paint is it not? could this lead to troubles when sanding next time round?
I am going to try a water based enamel on my cabinsides after painting the transom of my dinghy with some left over from my kitchen .This has stood up to total neglect for two years and hasnt chipped or faded. The other advantage is that I will be able to get three coats on in a fine day and save money by not having to buy turps for cleaning up. These enamels appear to be tougher than what I call latex type paints.
Thirty years ago they were a cottage industry firm employing half a dozen people in a shed somewhere (I exaggerate, but only slightly!) whereas they are now owned by a giant of the global marine paints business, Jotun, I think, they waste money on advertising which they never used to, and they bring out silly new paints, as you so rightly say.
The one good thing, from my point of view, is that their new owner brought them a hard racing antifouling, which they never used to have, and which is quite good. The "primer undercoat" you describe is rubbish, I quite agree, and they have obviously done something to their Grey Primer, the best paint they made, as it now says "not to be used under the w/l"!
I've talked to a number of WOODEN boat owners (the boats, not the owners). Without exception they have recommended 'Alkyd' paints, regardless of manufacturer. They are the only paints that are flexible enough to cope with the expansion/contraction of wooden hulls. What is important is to prime the wood as soon as you've scraped/sanded down to it.
I use regular Dulux gloss. Looks good throughout the season and rubs down easily the following year so it is easy to put anew top coat on in the Spring. Not expensive and you can tailor make your own colour. It is far easier to repaint a top coat than to polish fibreglass!
Good luck
