Phew!! it's not blue, thank goodness.My next boat is going to be raw fiberglass.Dennis does a nice build.The only thing that could be improved is the winch accessability it's not quite under the hatch and can be a PITA to work on if in a rush especially with the self tensioning drums i'm using the 55mm spiral works very good but complicated to install below deck.For international events i'm going to revert to standard drum and the rubberband they use for castration just in case a winch breaks down.

Hi Tug,
I owned a Croatian built Pikanto they use the 55mm spiral self tension drum on there boats and I had constant problems with the drums mostly the line coming off the spool for some reason, not what you want during races I ended up ditching it for a standard drum.

I now use 32mm self tensioning drums when I can.

Several weeks ago I reported how delighted I was with my Denis Astbury BritPOP. Superb build quality. Tug, sorry it is Blue. I am also perplexed with the inaccessibility of the drum winch. If the line becomes unraveled during an event I am screwed. But it is not the end of the world because I am not a real contender and languish in the back of the pack. Who cares about the shifts, in the end all that matters is there enough ice to keep the adult beverages cold.

I am using a 32mm self tensioning drum. Don't expect it to unravel because the return line tubes which go through the bulkhead line up perfectly with the drum. Sailing in a three day event in the Columbia Gorge at Hood River this weekend. This will be good test to see how the boat and winch hold up under potentially extreme conditions.

I have had my blue Denis Astbury boat out twice now, and I use the castration band and a 42 mm winch. No self-tensioners for me. Works great. BTW, I have the best looking blue Britpop going! Just ask me!

gp,

When the lines wrap around the winch drums the diameter changes as they rotate and one side gets bigger and the other gets smaller, so the lines change in length. The castration device is an 0-ring about a half inch (12mm) in diameter and is used on the tension line, not the line that actually pulls in the sails. It is stretched so that it keeps tension on the lines so they do not come unwrapped from the winch drum. I use a spring on my boat that is about an inch long (25mm) and about 1/8 (3 or 4mm) in diameter, I have it pulled to about 1 1/2 (35mm) inch long to keep tension on the slack line.

The self tensioning drum these guys are talking about changes diameter by being two pieces and is spring loaded and requires a little effort to get it wrapped properly.

If the winch drum is out in the open it is pretty easy to do, when it is under the deck it is not so easy...hence the discussion.

It worked wow,i am not having a problem with this drum just saying you ain't gonna fix this in a flash other wise it actually works good and i like it but it scares me should something go wrong having traveled to an event.The string changes angle in diamiter and height as the winch spins so i put it on floating blocks so it determines the angle it wants automatically i glassed on the tab that the blocks are tied to and i've now made the blocks into a doubble by bolting them together ,the tubes are now straight so there's less friction there as well,adjusting the tension on the spring is also tricky because the tension drum is a fixed diamiter and the spiral changes constantly resulting in it having tight tension when trimmed in but slack when released so i had to include a ring externally and adjust the tension when it's out but making shure you have'nt bound up the spring when you're trimmed in,you just got to mess with it til you get it right and it's fine,it would be a piece of cake if it were external so be it.The next thing i have to do now is drill a hole through the deck so i can tighten the screw on the drum lol or wait for one from Aus.How i do that now is grab the screw with a pliers and spin the winch with the radio.These bloody blue boats i tell ya pace on.
