As long as you can keep water coming into the intake and some forward momentum you can get away with a lot. Otherwise you step out and push. The competition jetsprints are mad: dragster acceleration, with high G turns, in a foot of water. The naviguesser works rather hard! 1 Share this post Link to post Share on other sites

Panoramix 1,285 #611 Posted December 8, 2018 13 hours ago, Zonker said: The crossover point is generally accepted to be around 25-30 knots. Above that range, the extra drag of a rotating prop shaft, P bracket, and rudder starts to really count. Below that range, the smaller impeller of a waterjet (and internal duct resistance) makes waterjets less efficient. I also like surface drives for very fast boats. Really good efficiencies because you're turning a big prop and rudder chores are handled by swinging drive left/right (though some have external rudders). Not so good in reverse or at slow speeds where the waterjets still work OK Thanks for the qualified answer! I've always wondered whether one could strap a jetski waterjet unit to a small diesel (redneck engineering style!) to power a relatively small boat suitable for fishing bass, retrieving lobster pots and also for the odd time you need to support a scuba diver. I imagine a relatively slender say 25ft plywood boat - just wide enough to retrieve pots safely - obviously a big plus of the waterjet is that there is no propeller in the water, doing 12 knots would be good enough.

Bob Perry 854 #614 Posted December 8, 2018 I don't mind that Pelorus. It ain't pretty but in that JEEP sense of utilitarian styling it works for my eye. I would make the cove stripe more delicate and stop it shorter of the ends. I'd give the boat a tapered bootstripe, not too wide. I'd paint the deck a very light grey/green or grey/blue or maybe a very light tan. I'd use dark curtains in those big windows. The more I look at it the more I like it. That's a sweet hull.

From what you say the boat would be too slwo for fuel economy to be on the list of advantages! The short answer is "not a great idea" Long answer - prop efficiency is proportional to diameter. Big slow turning props (think freighters) are very efficient at providing thrust. Small props have to turn faster to generate thrust but run into tip speed issues (> speed of sound for air propellers; back cavitation for water propellers). So a jetski moving very fast uses a tiny impeller so tip speed doesn't get too high, but that same prop is pretty poor at pushing any significant hull. Jet outboards (either factory conversions or aftermarket) are a thing. But while good for really shallow water, they are only about 2/3 as efficient as a good outboard prop. I'd consider those before a jet ski conversion because the impeller diameter will be a lot bigger than a jetski - and lots less engineering to make it work. It's just an outboard with a modified lower section. Waterjet bottom shapes have to be carefully designed to avoid getting air bubbles into the jet intake.

Bob Perry 854 #631 Posted December 11, 2018 Tricky; Most powerboats have some detail at the chine to deflect the spray. It can be a small, molded in, horizontal "flat' running the length of the chine, this is common.. Or it ca be an added strip shaped with a flat bottom just big enough to deflect the spray. When I tank tested the model for my 42' powerboat I tried it with and without the spray knocker. I was interested in finding out exactly how far forward I needed to run the spray knocker. With no spray knock the boat was impossible. Water just peeled up the topsides and looked like it would shower into the cockpit area. On my Lobster boat inspired powerboat the spray knocker is clearly visible forward.

Chine, rails or spray deflectors but not `spray knockers'. I find the spray knocker on that Wylie powerboat a bit weird; It is rounded so the spray can't necessarily release off them. I think they were done that way just to be different. No other powerboat had successfully used rounded chines or rounded `spray knockers' and I'd say there is a good reason for that!!

Sail4beer 2,090 #636 Posted December 13, 2018 Of course the reverse chine in speedboats can solve the spray problem and provides more lift and stability in turns compared to a typical v hulls. I have a Larson with a stepped hull. It looks like a dry ride. I wouldn’t know though, it’s getting a new motor and going wwaayyy down the road to a new owner.

Kirwan 324 #662 Posted December 17, 2018 Looking at the web page for those enclosures, they say it's a 'proprietary blend' plastic, but also indicate they use both acrylic and polycarbonate. Acrylic is nice and clear, is easy to work with, but not very impact resistant; likes to crack and craze (never use alcohol on it!, especially the extruded grades) Polycarbonate has 40 times the impact resistance of Acrylic.

The idea of a dodger is to keep rain/spray/wind out of the cockpit. That is a canvas maker that doesn't sail. The gap should be minimal or plastic grommets to take the ropes through with tight clearances. They didn't do it that way so the crew could use bigger ropes if the wind picked up?

Not my design choice but if you want serious interior volume and no weather decks and a large forward pedestal cockpit it’s not bad. "nice hollow in the bow"? You know nothing about yacht design. 'good sheer"? What the hell does that mean? An aft mount for the dinghy engine is one of the big positive points? Are you kidding? Nothing you mentioned overcomes the tragic hull shape and ridiculous deck layout. It is simply a POS design. Share this post Link to post Share on other sites

Sail4beer 2,090 #671 Posted December 21, 2018 Ahh, now I get it. Nice one!! Pick a boat designed for the masses and not a one off for a specific client. The design may be ugly to your eye, but it was designed and built the way the guy with the money wanted it built. That makes it a great design. Hollow bow entry sheds any water from a wave and keeps the bow up and the sheer has a nice shape to it complemented by the sheer stripe. Rather attractive to me and purpose built for a tougher environment than you can handle Air. Share this post Link to post Share on other sites

Just to score points with the guy whose cock you love to suck you will just make up silly hydrodynamic theory? My, I thought you were a Beta, but even that would be a step up for you. Just look at yourself! A man would be ashamed. Ooooh, the sheer and the sheer stripe are parallel! Doesn't that just make up for this POS hull and deck? Guess that stripe makes the boat a wonder in all conditions! Share this post Link to post Share on other sites

Sail4beer 2,090 #685 Posted December 21, 2018 I’m guessing it took you a while to peruse Perry ‘s Catalogue of designs to find one you don’t like because you were quiet for a whole week. Share this post Link to post Share on other sites

Naw. Some of us have lives. It's easy to find Perry boats that are ugly. He designs cartoons of the Edsels of the sea. Low IQ folks love that stuff. Look like the boats that were in their preschool books. Share this post Link to post Share on other sites
