Re: Use For An Inboard Engine Vacuum Pump?

I believe that a vacuum pump is commonly fitted to road vehicle diesel engines to feed the brake servo/booster - something to do with diesels not creating enough low pressure in the inlet manifold to power the brakes. If this is the case, there would be no use for the vacuum pump on a boat. But I wo...

Re: Hi from Europe

Hi Tomas! I'm in Europe (for the moment) and don't have much time either. But even 15 minutes in the shed can achieve something on a boat build. I've been cutting frame members one per evening (not every day) which is less than a 30 minute commitment but still feels like progress.

Re: UK Zip Build

Mike, I'm not sure how the boards were sawn - I believe they're quarter sawn but don't have the experience to say for sure. Yes, I too think that 1/4" is probably OK but 1/2" probably isn't! But 1/2" on a deck beam can be dialled out when the deck supports are fitted between frames, I...

UK Zip Build

I've changed my mind about what I build more times than I can remember myself but with the Ebihen 16, once I started I realised I'd bitten off more than I could chew (it's a BIG boat to build in a garage) so I'm back where I started with a Zip. And I'm just getting on with it, not worrying about it ...

Re: Outboard vs Inboard with same hp on similar hull

I've always wondered about a liquid cooled snowmoble engine using a clutch setup somehow. I don't have any knowledge of snowmobiles but I'd imagine they must have some sort of clutch fitted to allow them to idle without moving? Do they have reverse gear? You'd still have the challenge of cooling th...

Re: Outboard vs Inboard with same hp on similar hull

The Vanguard appears to rev to only 3,600rpm which is a pretty limited rev range - diesels rev higher than that! There's an option of a "High Speed 4750rpm Package", though. A whole 4,750.... I'd worry about airflow as stated above. I would have thought a better donor would be a jetski - a...

Re: Barrelbacked Overniter Build in UK

Thank you both. If there is interest I'll post photos of my build on here - I wasn't sure whether it was frowned upon to do that. I know you're posting about your Bartender, Bill, but you've 'qualified' by building the Tahoe first :lol:

Re: Barrelbacked Overniter Build in UK

After many sleepless nights pondering boaty matters I have come to the conclusion that my Overniter project won't become reality. I have been sailing for over 40 years, on and off - anything from 10' to 80' - and my wife has been making ever more frequent comments about me teaching our daughter to s...

Re: Beale Park Show - UK

That new boat from Jackson Yachts was a bit of an odd one to my mind. 'Traditional' mahogany finish but all the locker doors in the cockpit were modern black plastic which just didn't look right. The shape was quite modern and the transom treatment didn't work for me but the biggest eye-opener, as y...

Re: Catastrophe

There are too many options and the choice of those is down to the individual as well as affected by what's available in the country/area you live in. Steering can be hydraulic or mechanical. Things like the exhaust, shift linkages etc will depend upon your choice of engine/gearbox. Lights will depen...

Re: Best substitution for Honduras Mahogany

And it is going to be hilarious when I ask one of the old timers at my favorite hardwood store what the species is of the Phillipine Mahogany they have. My guess is the response will be something like, "pieces of what?". I would say that if they don't know their timber then you're shoppin...
