hydrofield jaguar 8.8 rebuild

We'll see I suppose. If the designer didn't think it had advantages over a mono then he would have just designed a mono. It seems many of these hulls went to the military as mine sweepers and drones, police, search and rescue etc I'm not sure what their requirements were so who knows what the design criterion was. I assume maximum speed over anything else. I could ask him maybe, hydrofield still exists so anythings possible.

Ah yes a space for your toes to fit. The thing is if I lower the sole the gunwale is going to be really high. This thing is super deep sided if I stand in the middle of the tank coffin I can't see over the sides. I think it being a multi hull even if the sole is higher than a mono hull the extra stability will make up for it. I think it will be fine

I'm an auto elec and I've wired up quite a few of them. Easy as pie. a few constant powers an ignition switched input the fuel pump trigger and that's about it. You can get them with electronic throttle bodies I can do that too they communicate to the throttle with serial data that would mean no throttle cable but more complicated things to be destroyed by salty water. The ecu in the car has security that communicates with the key head they call it VATS there's software that I have that can remap them to turn off the VATS the wiring looms are pretty much good to use straight away. All the plugs are water tight the ecu lives in the engine bay in the car so it's all sealed up and there's only a few wires that you don't need from the car like the air cond and fan triggers and a whole bunch of stuff to chop off if it's auto trans

I was just going to put the whole pump module straight into the tank it's got the surge tank the pump the level sender and the pressure regulator all built in. And all that's outside the tank is the filter and these engines don't have a return line so only one hose needed

Your in the right trade for the efi conversion. There was a thread a couple of years back about converting efi but I think you provided more information in this post than that whole thread did.

The ply is CD grade structural with A bond UF glue and I made some cleats. I ripped up some 90x45 MGP10 Pine into half to make 45x45 and routed a 20mm radius on the corners. I suppose I'll build some fillets with some thickened epoxy and some plastic spoons as the tool to get the cloth to lay down nice in the corners and to spread the forces

What do you guys think is a good weight of cloth to use for sealing these sole supports up. Using epoxy of course. I'd like to do it with one layer of cloth with a pre coat to seal the ply and a weave fill coat after to smooth it out so I don't know other than to ask the supplier. None of these parts are structural. They're just there to hold the floor up. But I'll probably keep this pile of junk for a while so it would be good if it lasted long enough for me never to think about it ever again

Oh and I put the gimble housing and transom plate on because it only took me an hour to make the cleats so I thought I'd better make use of my day. It was a bit fiddly but it got done in the end. The transom plate isn't flat on the back and needs reliving for the exhaust on the inside. So I got to grind fiberglass again. Oh joy of joys

Speed Potential?

Mr Efficiency said: ↑

The Hydrofield is an interesting old boat. In their original conception, the side "wings" were not truncated amidships, and the central hull continued right aft without the step, and its air vent. It was a successful enough offshore boat, unlike most cathedral hulls, which slammed mercilessly, largely because they bottomed out badly. This one maintained enough clearance in the tunnels to absorb wave impacts. But it was never a boat with much speed potential, as the wetted area was quite high, although it could hold plane at quite modest speeds. One might assume cutting off the gull wings, and the stepped hull modification, reduced that wetted area substantially, as well as altered the turning circle and handling, somewhat. Not sure this type of boat has been fully developed, and the potential maximised. The advantage it seemed to have over cats was the ability to run well with a single engine.

My 5m Hydrofield Jaguar does 40knots (WOT) with a 140 Merc.

Your 5m Hydrofield is not one of the early ones, though, is it ?

Ejshane · Aug 10, 2015

I think it's 1990ish. I'm not sure when they started production.

Projects still ongoing. I've been building a house. So money and time are in high demand. Still pretty much as in the photos except all the sub floor is glassed in with epoxy. Doesn't help it's located 2 hours drive from where I live
