Engines V: Lessons Learned - The Trial

This will be the last blog on engines for a while.  We know that we have inundated you with engine informatio, but hope the information is helpful to you.  If you have any questions please feel free to contact us or write questions in the comments.  We will either answer your question in a separate blog or right on the thread.

As a recap, we have discussed several aspects of engines:  fuel efficiency, fuel type, engine type, and calculations.  But one thing we discovered during engine trials are the lessons that we learned.

One of the most fun and truly challenging parts of building the Grampstr's Pride was the Trial phase.  What made this fun was that we had some really cool experts on our boat to show us how to run the equipment and do some fine tuning.  During this process we had the opportunity to watch the experts at Endeavour, Cummins, and Twin Disk make the Grampstr's Pride ready and sea-worthy.  While working on the vessel we learned a few things that affect the engine - what, you ask? Efficiency!

This is where we learned about the sweet spots for running the motor, prop size and pitch, and most importantly how much horse power was too much.  This is what made these trials so fascinating to us as owners and captains. The experts worked out kinks: such as propeller pitch, transmission controls, and jet thruster conversions.  In the end the issues were totally worth it and we are so excited to have had everyone on the Trawler at once. 

Although this is the last blog on the engine series, you can look forward to future blog posts when we will talk about all of the great technology on the Trawler.


Ask the Capt: Why do you stay at Yacht Clubs as Instead of Dropping Anchor

This post is to answer a question written on the adventures page about why we stay at Yacht Clubs instead of just dropping anchor. 

First, we want to thank Felix for asking this excellent question. The answer to this question is really not all that difficult, but we thought it would be worth a blog post nonetheless.  The answer is YES, we can absolutely drop anchor out on the water and spend the night or even a week. 

The choice to drop anchor or spend the night out on the water is really up to our clients.  In this case, our clients desired to spend the nights at some great Yacht Clubs. The great thing with choosing to charter is that as a client you get to choose how your experience is shaped.  We do our best to please our clients and give them a great experience.   

If you choose to start out on the water we have state of the art equipment on the Grampstr's Pride to provide some extra comfort while staying out on the open ocean.  The first is our Anchor.  We choose to outfit our boat with an Ultra Anchor. Our anchor has several great features that are exceptional for the seas and bays alike.  The second is our Twin Disc propulsion system, which ensure the boat rests nicely in the waves and gives our clients the peace of mind and comfort they deserve.

We make two promises to our clients: the first is that you will have a unique charter experience; and, the second is the promise that you have the ability to plan your trip.

Engines IV: Yanmar V Cummins Marine Engines

As some of you may have realized we used to own the Grampstr's Endeavour a 38ft TrawlerCat, which was a beautiful trawler and in the future we will discuss our transition to the Grampstr's Pride, a 48ft TrawlerCat, but for now we are going to discuss one big difference -the engines. 

The Grampstr's Endeavour had two Yanmar Diesel engines.  Whereas, the Grampstr's Pride  has two tier 3 Cummins QSB 6.7ltr Turbo marine Diesel engines.  So the question you may be wondering is why the change in engines?



Lets first discuss the reasons why we did not go with another type of engine. It was not because there were issues with the Yanmar Diesel engines.  Yanmar has a great Marine reputation and has an excellent product.  It was also not because they did not have an engine that would propel the larger boat.  Yanmar has an excellent series of engines for most size watercraft.

The reason we went with the Cummins engines over the Yanmar was fuel efficiency.  After lots of research it turned out that Cummins Tier 3 engine was going to deliver a lot more efficiency and power for the size and type of trawler we were building.  After lots of discussion with Endeavour it was decided that this would be a good way to go.

As we have discussed there are a lot of things that go into choosing an engine.  If you have any questions on why we choose the engine we did please reach out to us.


We hope you will charter with us soon!
