    Repair Raymarine Tiller Pilot Drive (Q047)

    Just pulling the seal on the ram and giving it all a good film of suspension grease (slick honey) has made everything a lot smoother. I was happy to see a ball screw inside, I assumed it was just acme thread or something.

    Repair Raymarine Tiller Pilot Drive (Q047)

    Thanks, I got curious and figured it out as you were posting. The end with the ram unscrews using a pin spanner (common bike tool) and the other end breaks at the red line like you said. Then the motor pops right out and gives you access to the wires. The cable glands just unscrewed with...

    Repair Raymarine Tiller Pilot Drive (Q047)

    This is the tiller drive that has come with many generations of Raymarine autopilot like the Evo, X5, and ST4000. It looks like this: I want to replace the cable on ours -- there seems to be an intermittent break and it is a little too short anyway. Has anyone taken one of these apart? My...

    Raymarine ST60 Tridata Calibration

    This is another reason to consider the itc5 and i70s.

    WTF is going on with Raymarine?

    I think the update rate is higher on the itc5, but could be wrong. It is also likely lower latency because there are fewer hops from masthead wand to the autopilot.

    WTF is going on with Raymarine?

    You can use a Raymarine iTC5 instead of the ST/NG gateway to interface your existing transducers. This gives you the performance of what they are selling today and will give you responsive steering to wind. Any ST60 displays won’t work anymore, but you might be happier replacing them with i70s...

    Carbon Fiber Spinnaker Pole???

    Our clear pole has no chips and the painted pole got a lot of them, both measured after a similar schedule of 3 years of racing. Maybe the painted one was poorly painted. I paint CF that lives outside (like we're getting a CF sprit right now and it will be painted to match our hull). Our spin...

    Carbon Fiber Spinnaker Pole???

    I raced on a boat with a painted pole. It works, but it's another thing to maintain, it'll get chipped over time. I'd still store it inside. Express 37 and J/35 have similar enough interiors, I know the pole will fit.

    Carbon Fiber Spinnaker Pole???

    I had to replace the one on my Express 37 a few years back and my rigger used a tapered Forte pole. It works well for us. A lot of the choice was driven by availability, at the time C-Tech and Forespar were going to take too long to deliver it. We use Forespar ends in the pole and I think...

    John Kretschmer dismasting

    I should have mentioned that I checked McMaster Carr and Online Metals before asking. Both have al bronze bars, but not si bronze. Aluminum Bronze 954 is quite well priced and has yield of 32ksi and tensile of 85ksi, so just under 316 properties. 932 is quite a bit weaker (and more...

    John Kretschmer dismasting

    Silicon bronze and Ti have both come up as good metallic replacements for 316. Is there any reason to pick one or the other? Who sells silicone bronze (finished or raw) for chainplates?

    You're not qualified to have lithium batteries

    NYC has a huge business for Alibaba grade e-bikes being used as delivery bikes. Those batteries are typically low grade and with the cheapest BMS’s. Hopefully that isn’t what most people are putting in their boats (but I know some are). I just put in a lithium bank and it was pretty...

    Schock 35 dilemma - I could use some help, or....

    I enjoy carcrash's posts and have liked seeing what he's done with his Olson 40 (including the electric engine). However he's not a very reliable source of data. I'm still waiting to see the 14' sprit that he was going to make out of his old spinnaker pole...

    Schock 35 dilemma - I could use some help, or....

    Beta sells them and is working with Hybrid Marine in the UK on the setup. https://www.hybridmarine.co.uk/images/Documents/Hybrid_HE_SB-221-21138_REV-00_-_0519_W.pdf It's a compelling solution but also a lot of weight to put in a lighter displacement racer/cruiser. At a minimum you have the...

    Schock 35 dilemma - I could use some help, or....

    I've read this, and it's compelling, but I've never seen actual useful data. Assuming I have a 3 knot average headwind at 20 degrees off of the nose, flat water, and want to go 6 knots speed through water. That is a very standard delivery in Puget Sound. How much sustained power would this...

    Schock 35 dilemma - I could use some help, or....

    You also need a 48V/35A charger for each of those generators. Those are about $500ea. 3 of them (better suited for a Schock 35) running simultaneously on deck is a noise that would get me wishing for a loud diesel. I looked at this a few weeks ago and don't understand why 2kw generators are...

    Schock 35 dilemma - I could use some help, or....

    Rather than getting too stuck on hp vs electrical power you can use the Oceanvolt estimator (which I'm going to assume is optimistic). This is what it shows for my Express 37 -- the numbers should be almost identical for a Schock 35. Y axis is kw, X axis is speed in knots. At 6 knots they...

    Schock 35 dilemma - I could use some help, or....

    If the 3GMF in my Express 37 died I would start shopping for a used 3GM to put in place. That seems like the cheapest and easiest way to get the boat moving again. The backup choice would be a ~25hp Beta. I think of the Express 37, Schock 35, and J/35 as somewhat kindred spirits. I really...

    Had/know any Express 37 rig or boat issues happen while crossing pacific?

    I'm glad pnwer came in to tell Perplexity's story with the whale. I didn't want to tell it for him, but it's a good story and was a good reminder of the importance of a proper e-rudder. It was nice seeing an Express 37 in Lahiana and I hope you have a good trip.

    Identify this unusual 45' boat?

    but with a center cockpit. It's weird to see a low slung boat with a center cockpit. I did a quick scan (a couple of minutes) of SailboatData and couldn't find it.
