Russell Brown 1,240 Posted December 14, 2021 Share Posted December 14, 2021 This is a pretty cool thread. Nige's tastes are the closest to my own, of corse, but kim's 50 footer having ample power with 400 horsepower is pretty cool. That's less power than lots of 20 footers have nowadays. The Bieker 30 footer made from a recycled Ultimate 30 was what got me interested in powerboats. That boat goes a lot of miles every year and the owners love it. The single outrigger still seems like the best option to me for a single engine multihull, but my brain can handle asymmetry and most people can't. I should have built one for myself instead of another power cat, but I had the hulls and needed a project. The single outrigger in the photo is "experienced". That's a Bolger "Slicer" in the photo too. A really good boat. 4 Quote Link to post Share on other sites

USA 007 162 Posted December 14, 2021 Share Posted December 14, 2021 Here's a different take on sailors powerboat. My Dad and I have covered over 6,000 miles. Mississippi River from Minneapolis to the Gulf. Missouri River from Yankton SD to St Louis. Ohio River from Pittsburg to Paducah, KY. The Tennessee-Tombigbee waterway from the Ohio river to the gulf. The Flint river from Albany, GA to the gulf. And I'm sure there are a few more in there. Not to mention many days spent duck hunting and fishing. May I present to you M/V Dumarse - 16ft Express aluminum boat with a 4-stroke 20hp Yamaha. It burns 2 gal/hour cruising at 22-27 knots depending on the push of the current. 5 Quote Link to post Share on other sites

My 5,000 lb I/O won't run at 16 knots, 22 is more like the minimum. It's just too heavy to be planing efficiently at that speed. My next boat will be lighter because I like 16 knots a lot better than 22-30. Quote Link to post Share on other sites

Hey any catamaran or "slightly off" catamaran with 1 engine in one hull will be very challenging to dock. With our 40' cat with a single diesel in one hull, if we were docking and the auxiliary outboard on the other hull wasn't working my wife would curse me. Actually you could do the same on the Aspen - drive it on the inboard diesel 98% of the time and use a small outboard (instead of a thruster) on the other hull as the "get home" engine or just for docking. Also would mess with people's minds because they would only see the little outboard. Quote Link to post Share on other sites

When the boy (last kid) goes off to college in the not too distant future, we are outta SoCal and most likely headed back to the Chesapeake Bay. We have a small condo at the top of the Blue Ridge Mountains of Virginia (at Wintergreen) that we will live in part of the year, and are talking either a small house (condo/townhouse) somewhere on the coast on the water, and a powerboat for cruising and a smaller daysailer for racing/daysailing. So the the budget depends alot on location/price of the house on the coast. Lets use 100k for both powerboat and daysailer. I'm the kinda guy that likes making things look good, so I actually don't mind varnishing...and it might help keep me busy whence I'm retired I like the look of the Nordic Tugs better than the newer Ranger Tugs. Found the Cape Dory 28 ft Cruiser and the Grand Banks...but both of those are a question of finding one that has been well cared for by it's POs... Of course, I really like the downeast look of the Hinckley Picnic Boats, the MJM's, the Black Cove's, etc. but to get the desired cruising accommodations means a much bigger boat and budget goes thru the roof...

steele 201 Posted December 17, 2021 Share Posted December 17, 2021 A smaller option is the Camano Troll. Not a looker, but well built and efficient Both Aspen cats and Ranger tugs are going to outboard power for most of their models. I can see lot's of advantages, but a big issue is the loss of the swim step as a great place for the dingy. Ranger has a tilting rack that holds the dink over the motors, it works but looks clunky. The Aspens have two outboards, with the one on the smaller hull having lower HP. To my mind this kind of defeats the advantage of the asymetrical layout with just one inboard in the big hull. A friend has an inboard Aspen, it is a nice boat but backing up is a bit of an adventure. It is one of the smaller models which puts the engine partly under the cabin so it is quite loud inside underway. Quote Link to post Share on other sites

Cheap Beer 21 Posted December 17, 2021 Share Posted December 17, 2021 I might as well wade into this thread since it's a subject close to my heart. I'm a sailor and yacht designer and have been considering the sail or powerboat conundrum for as long as I've had to motor my 5kt $hitbox back to port on a windless/blowing stink/cold/rainy/dark/hot/day/night. Still love sailing, but if I want to get somewhere comfortably, it'll be on a powerboat. In the last few years, I started thinking of a smaller powerboat- a day or weekend boat. A boat that could be trailered and stored for the winter, like our 26' sailboat. So she needed to be relatively lightweight, efficient, max length and beam for trailering, and a reasonable cruise speed in the low 20's. The Tombolo 28 was originally designed for cedar-strip & plywood custom construction. The design was published in a few magazines and now it seems to have a little momentum. https://www.siewertdesign.com/Portfolio/Production_Boat_Designs/tombolo_28.html Many production boats the size have what I call "feature creep", and try to do too much to appeal to everybody. They have too many and overly complicated systems, which weigh more, which require more horsepower, which weighs more...etc. The Tombolo 28 is a relatively simple boat, a sailors' boat that I thought you might enjoy. 11 Quote Link to post Share on other sites

A boat that could be trailered and stored for the winter, like our 26' sailboat. So she needed to be relatively lightweight, efficient, max length and beam for trailering, and a reasonable cruise speed in the low 20's. The Tombolo 28 was originally designed for cedar-strip & plywood custom construction. The design was published in a few magazines and now it seems to have a little momentum. https://www.siewertdesign.com/Portfolio/Production_Boat_Designs/tombolo_28.html Many production boats the size have what I call "feature creep", and try to do too much to appeal to everybody. They have too many and overly complicated systems, which weigh more, which require more horsepower, which weighs more...etc. The Tombolo 28 is a relatively simple boat, a sailors' boat that I thought you might enjoy. Very nice! Quote Link to post Share on other sites

I am rather proud of the fact that I batted feature creep away from the SLIVER project. It wasn’t easy, all sorts of well meaning people had suggestions of features that “you need” or “must have”. So far we have kept her quite simple. 9 Quote Link to post Share on other sites

Autonomous 1,233 Posted December 18, 2021 Share Posted December 18, 2021 Feature creep. So true. One of the reasons I liked my C-Dory so much was that it had what you needed and nothing else. More time boating, less time maintaining stuff. 2 Quote Link to post Share on other sites
Pertinacious Tom 1,931 Posted December 19, 2021 Share Posted December 19, 2021 Ranger Tugs are all about feature creep. There's almost nothing optional. Thrusters, radar, giant screen, air conditioning, etc, etc, it's all standard. I'm not a yuge fan, as one of my rules of boating is that the smallest, simplest boat that can do what you want to do will result in the best work to play ratio. They kinda went the opposite way. As mentioned, I sold them for a while at a dealership. Customers LOVE standard stuff and do not like poring over lists of expensive options. Not my style, as I said, but if I had to sell one of those with every option priced separately or sell one like they do, it's an easy choice. LOAD IT UP! Quote Link to post Share on other sites

This test just came out (literally hit my inbox a few min ago) & looks quite promising. ~16% speed & efficiency improvement, pretty rigorous independent test from what I can tell. Humph. First, note that it only works at lower speeds, and is worse at higher speeds. It is at higher speeds when load is maximized that cavitation happens and tip losses become significant, not at mid range speeds. At lower speeds, more blades work better, and this has always been known, nothing new here. This is effectively a six bladed prop being compared to a three bladed prop, so the results are not at all unexpected. A better comparison would be against a six bladed prop without the connections between alternating blades. Tip loss on a prop is not like tip loss on a wing, where winglets certainly work. No helicopter uses winglets. That is because a rotating wing approaches the fifth power better efficiency with span, so increasing span always wins. The real problem with reaching best efficiency with this specific (heavy, high drag) boat is that it needs bigger diameter props than can be fitted on those outboards. Better to improve the lower unit to support bigger props in order to gain better mid range efficiency. Remember that the reason outboards use small props is because gas engines don't have much torque at low speeds. Outboard manufacturers, like all engine manufacturers, don't want you to overload the engine at low speeds to avoid having you blow up your engine. Overloading so the engine simply can't turn faster than the torque peak is the way to get maximum fuel efficiency, and everyone knows that. But it also causes engines to blow up, and everyone knows that too. It does look cool. 2 Quote Link to post Share on other sites

Pertinacious Tom 1,931 Posted December 21, 2021 Share Posted December 21, 2021 That outboard looks too big for that boat. I'm not sure a boat has ever gotten that reaction from me. If you look at hours on the water, I'm definitely a powerboater who also sails and paddles. Cruising up the harbor yesterday at 20 knots, an offshore fishing type cruised right by doing about 35. My wife commented that we were losing the race. I told her that boat was cruising near our top speed. Got to the ramp and the boat in question was helping a disabled boat at the mouth of the harbor. About 24' long. The engine? A 400! I grinned. DIdn't look too big. Quote Link to post Share on other sites
Autonomous 1,233 Posted December 21, 2021 Share Posted December 21, 2021 Don't know how closely some of you are watching the outboard motor market but it is brutal. Guys have brand new boats with no motors and no idea when they will come in. Year long waiting lists, etc. I just got notified my new build was imminent (whatever that means), I thought it would be late spring. A bit of panic as a specific motor needed to be sourced pronto. Called and surfed around with the same result, 'we can put you on a list.' Finally found just the one I wanted, probably the last one in the area. It's better to be lucky than good.

socalrider 710 Posted December 22, 2021 Share Posted December 22, 2021 Nimbus looks like it makes good candidates for a Sailor's Powerboat. Solid economy at low speeds with ability to go fast, Swedish built. Pricey. I've seen a couple in person and think they look great in profile. The asymmetry is off-putting when viewing from the bow or stern. https://boattest.com/boat/nimbus/365-coupe-2020 Quote Link to post Share on other sites

Pertinacious Tom 1,931 Posted December 27, 2021 Share Posted December 27, 2021 This thread could use updated Cowmaran pictures and I happened to swipe some from the owner's FB page, so... With the brand new Suzuki 20's. That T-Top is a pretty cool carbon fiber structure on its own. And a look down under the bridgedeck. The beams that support the bridgedeck are 4 x 4 carbon fiber posts with very thick walls. They're way too strong and heavy for the purpose, but were leftovers from one of his kids. The first time I drove it through really steep harbor chop, one of those took the top of a wave off. Felt like we hit something really solid. 2 Quote Link to post Share on other sites
