....but some of the same rationale.
From MVWeebles in the on going FPB thread:
"FPB is an amazing design. $1.5m - $2.0m is a lot of money. But there's a solid market for yachts in that price range. They are perhaps a slight premium over a comparable Nordhavn for example. A much different boat.
Crossing an ocean at a solid 12 kts - almost 300 nm days - is incredible."
Admittedly, I have a pretty bad boat jones, but not that kind of boat jones. Still, the idea of a faster, highly efficient, ocean capable cruise is what caught my eye with my new ride. (also, and to no small degree, value)
Every boat is a compromise and the other boat on my wish list at the time of this purchase was a 68x14 aluminum ocean cruiser. In the end, what put me off that one and onto the powercat was the 'not at cruise' platform that it represents. Even as a world cruiser for the last ten years with 53000 nm, 45 countries, and three crossings, it will still be true that during those 10 years that 94% of the time the boat is not in motion. The monohull at 14 beam had much less space above the water, less access to the water and around 50% of its interior volume dedicated to sleeping area. Way too little outdoor hangout space. Seemed absurd when I thought about that for mostly a cruising couple that really enjoys watersports and hanging out on deck.
The cat solved that and still offered an incredible range and designed, as the FPB, for comfortable uphill travel which I hope we will benefit from in travelling between the PNW and Sea of Cortez seasonally.
High prismatic coefficient hull and good behavior beating to weather is what Malcom Tennant, the designer, was targeting, and like Dashew, did a good share of his work on sailing vessels. I think the result in this design is a hybrid between something like Beowulf and the FPB.
The entry forward is very fine (see photo) for slicing into head seas but then plenty of reserve buoyancy as you get above the waterline. The helmsman sits at the metacenter. Lots of rudder and twin propulsion spaced far apart should make downhill control pretty effective as well. Twin Simrad AP will help with that.
Her cruising groove is around 11kn and she burns just over 5 gph at that speed. I have seen video of her making 17kn into a 20kn wind on her nose and the ride appears to be quite comfortable. The top end of her recent sea trial was 24.5kn!
The tunnel design under the bridge deck is to prevent the slap in flatter designs and to create a pressurized air cushion as the vessel descends after topping a sea. The hulls have a canoe form aft. In a video of 12kn cruise, this combination resulted in zero bow wave and real flat and quiet behind her.
Given the strange times we live in, I had to make this leap remotely. Thus, there is a real chance I will be disappointed but given how much I have studied this, I don't expect that will be the case.
Quite the leap it is for sure. Her FRP build took me awhile to consider given what I currently drive and I have no experience with the motion in a multihull in this size range. But, given 65+ feet of boat travelling at these speeds and still over 2nmpg is something I needed to try.
Time will tell. I am excited to try and will get a pretty good chance on her 2200 nm trip home!
