V Berth works some posts ago i showed a couple of photos with some lines scribbled, which represented a 3D volume for a new stbside locker. for that to happen i needed to epoxy another small wall to enable a surface onto which the locked could be tied to this is said small wall in 6mm G10 dry fit of...

hi Atomvoyager You mention exactly what i was fearing most. The thinner the sheet the worse the handling of it. Ideally i would have a small vaccum pump and use that to keep them in place whislt the adhesive cures, but i think im going to buy some cheap 3mm plywood and make "backing plates"...

Insulation ive decided a long time ago to insulate the boat a bit better, which is code for: giver her a little something since she has none, and being solid glass we all know how easy is for condensation to happen. ive chosen to go with cork, not the best material R value wise, not the lightest als...

the Bimini I had been researching for bimini shapes for hours on end, looking for a solution that wouldnt compro mise the boat's lines. It was when i was peeling the cabin top that i had an epiphany: why not use the cabin top as a mould for the bimini?! the asnwer had been there in front of my eyes ...

Admittedly, electrics is my achilles heel, so far. From research ive come te see that there are 2 big areas. The switched and unswitched one. The unswitched one deals with all power coming into the vessel, ie, anything that charges the batteries. Solar panels fall onto this area. Usually batteries a...

cockpit floor works this is a sequence of small jobs which needed done before i glass in the cockpit floor. first i needed to install some flooring in between those stringers. leaving it like that would create a spot where water would pool, so the goal was to avoid that. it also meant that, by glass...

Bilge keel bolt This project has been in the works since i changed the keel bolts. The goal was to isolate the aft most keel bolt from water inside the bilge compartment. for that i needed to build some partitions out of 3 mm G10. isolating the aft keel bolt.jpg Then i glassed them with 3 oz woven r...

i understand the difficulties with the owner being tall, and the need for higher hoisting points, those really impose on the final solution. on my boat im going to use the cabin top as a anchoring site for the panel. shading will be an issue as it always is at this location. since im running the lin...

pmnfernando

i reckon you can get a 200 watt semi flexible solar panel on top of the coach roof. if you bring the arch height down to in between the boom and the existing dodger you get yourself at a height for a solid bimini whose width may indeed follow the sheerline countour (top view) of the hull for the len...

looking very good!!

the only thing i really cant get onboard with is the arch. it ruins the boat lines imo.

too hot to work but not hot enough to not make progress on other smaller projects. i say i progressed....and i did.... but only after 3 hours + and some bits of G10 later. since the boat is being design for solo handling it makes sense having the lines led aft to the cockpit. i know this is a big to...

Hi Atomvoyager thanks for joining in on the discussion and bringing some experience. good to know that Jeffa's model suits the purpose. Its not that i wanted it to be bigger. Its just that when there is such a difference in a given dimension, and keepig in mind that more often than not, there is a r...

pmnfernando

slept on the tiller arm overall size and after using some of Jeffa's drawings i decided that the square sectio was indeed way to big for whats needed. i resized it to a 100mm square section and drop the bolts from M12 to M8 this is just a 3D model of the new size,it does feel more adequate in the en...

in the meanwhile got some answers from the raymarine tech. what a nice guy. gave me a very nice tip about splitting the 13 degree angle in half in order to educe the effort for the AP. This can be done by offsetting the fixed pin of the tiller on its initial position. easily done. great news, it mea...

i think i got the tiller arm and shaft designed. just waiting for the ppl at jefa rudders to clear a few questions and dimensions so i can go and order their tiller head Shaft max diameter is 60mm tapers to 40mm towards tiller head tapers to 30mm inside the rudder small (yellow)angled piece max diam...

pmnfernando

also got time to move forward about designing the shaft and playing with the flanged UHMWPE bearing i draw a couple of weeks ago. Upon imposing the bearing on the shaft arrangement it was visible that, to maintain the flange would force me to drop everything down to make space for it, plus some clea...

Managed to pass by the marina and took some measurements and angles from the rudder grp halves I was then possible to use autocad and easily determine the rudder area. Since i was able to pinpoint, as precisely as i could, the entry point of the rudder shaft i could also determine the rudder area fo...

got some answers from Raymarine. gotta say the fella that has been talking to me as been great. been pestering him for the last 2 days with questions back and forth. He doesnt seem keen on working around the 460 mm distance between the rudder axis and autopilot, and suggested a different AP model, w...

pmnfernando

for sure im making the good folks at Raymarine swear at me : "why is this guy complicating stuff that we've made easier", only with much more savoury language. all this because i want the tiller AP drive unit below decks and as much out of the way as possible. raymarine states a 460mm dist...

New chainplates redesign Since they have vanished also, it would be really stupid to not improve upon what´ve done almost 2 years ago. Its the same basic concept with a slightly different shape for all of them. I decided to reinforce the small chainplate by making a taper from the bottom to top, as ...

Hello CapnK Thanks for the support man, appreciated.

since i dont have the original rudder shaft to make a copy, im left wondering if i can take this oppurtunity to enhance the rudder shaft arrangement.

Hello Lloyd This is a major blow, quite devastated to be honest. Ive lost so much stuff that i dont even know the full extent of it.

i was feeling like templating a bit more and decided to have a crack at the V berth cabinetry felt like it was a good idea to template the port and center lockers in one piece since i had kinda guessed the actual piece would, not only fit in one half sheet of G10, but also fit thru the main bulklhea...

things are expensive in the US1 the whole lumber thing is a denomination by the sawmills, 1 inch is in fact 3/4 nominal , to have a 1 inch nominal you would have to ask for a 1 1/4 inch thick and so on, if memory serves. i dont really remember why is that but i would venture it is related to waste u...
