A New Angle With The Wicked FPB


The new Wicked FPB sports some hot angles, not the least of which is the glazing system surrounding the great room. There are numerous advantages to these outwardly angled windows.

Consider the following:

  • Windows stay drier (from the overhang) and water slips off faster. This means less salt build up and better visibility.
  • They are much easier to clean. Simply run a squeegee along the entire surface, rather than in and out of mullions.
  • One size storm shutter fits all.
  • Visual space on the inside is enhanced since your eye runs outward further.
  • Window coverings lie on the inside surface of mullions regardless of motion.
  • The air gap between window glass and shades -150mm/six inches – is a natural insulation barrier.
  • In cold, damp climates a simple clear film seal will create an insulating air pocket and eliminate condensation on the window glass.
  • The large overhang provides wonderful shading.

Outside, we have wider than normal side decks, with stanchions placed toward the outer edge of the rub rail (belting). This is to compensate for the outward push of the glass. Although the life lines are 1.1m/44″ tall, we want a hand hold system for going forward in adverse conditions. The solution will serve multiple purposes: there will be a “T” track fitted to the underside of the overhang over the center of the walkway. To this track will be fitted several sliding cars. If you need a handhold, grab a strap hanging off a car and slide it forward as you move down the deck. This can also be used with a safety harness. Furthermore, the straps can be used to transport heavy objects down the deck.

The only drawback we see is the cool – some would say yacht-like – appearance these windows convey. We prefer a workboat/military aesthetic, both to fit in better with commercial vessels and to give the bad guys pause. After struggling with this for a while we have come to the conclusion that the Wicked FPB’s combination of bare aluminum and hot angles will almost certainly cause those of nefarious bent to look for softer prey. And the commercial sailors? They’ll know what this design represents  and won’t be put off.

    You have managed to keep us riveted to the computer hitting the refresh button for the next update.
    Thank you:-)

  2. Steve B Says:

    Is the window-tint an applied film or is the glass itself tinted?

  3. Steve Dashew Says:

    Hi Steve:
    The window film is made by 3M, a ceramic (nonmetallic) product.

  4. Gerhard Says:

    I know the 3M films, to protect from sun. There are other security and safety films to protect glass doors and windows. Do you use this or (only) the light protecting versions?

    I like the angle of the windows. Looking at ~ 57 degrees removes all reflections.

  5. Steve Dashew Says:

    We just use t he film for UV protection and to reduce sun load.

  6. Steve B Says:

    …Actually, a lot of ‘stealth’ warships have pretty cool angular surfaces and shapes these days (albeit usually in the opposite direction)…seems to me that this new approach would still be in keeping with a modern “workboat/military aesthetic”

  7. Erik Says:

    Talking of nefarious characters Steve.. how secure are the FPB’s in terms of glass and door? bullet proof and blast proof? piracy is a real concern so would be great to know you can be secure inside in the event of attempted hijacking and point the boat towards the big ocean!



  8. Steve Dashew Says:

    Hi Erik:
    Best defense is to avoid confrontation and stay out of the areas where folks are heavily armed. Casual thieves will find it difficult to gain entry. But bullet/blst proof…. not likely.

  9. Alain M Says:

    Riveted, Raj You said right…
    Steve, I agree, this glazing type have many advantage, best for water itself sleep away, better insulation already as they are (they insulate the mullion), and like you said it gives one easy way to updated it if necessary from inside…
    The T track is also one way to easy fit the outside solar shade. And yes transport heavy object down the deck, like one storm anchor, is definitively one big plus…
    And if I guess well the best is to come… In one or two step? 😉
    Timing to finalize calculation about some design option, or simply Steve really enjoy drive us crazy, melting in front of our computer screen??? I guess both!!! 😉 And he is right…


  10. Matt Marsh Says:

    I don’t see much room for conventional pressure plates and gaskets around those windows (and in any case, pressure plates would mar the smooth appearance of the new design). Are you planning to use a structural adhesive/sealant approach for these windows- 3M VHB tape, perhaps, or the Dow 995 that’s used to glue skyscraper windows to their mullions?

  11. Steve Dashew Says:

    We have been gluing windows in for years so don’t think this will b a problem. There will be a storm shutter system, using threaded inserts welded to the aluminum as we do on the other boats.

  12. Norm Moore Says:

    Steve , I like the mullions. If those are 50mmx150mm then the weight should be slightly less than than 100mm square, but with an increase in their strength in the direction the water will probably hit.

  13. Alain M Says:

    Hi Steve
    Some size, proportion, when reports from one picture to another are questioning me!
    We are well below 115 feet, right?
    If I blow your theatric event, just delay the post as necessary, no problem!!!

    I really like the way it is going!!!

  14. Mike Holcomb Says:

    Steve another great design, but my question is range. Now at 11+ knots it states about 5000 NM range, how much could you actual range could you get with lower RPM?

  15. Steve Dashew Says:

    The increase in range that comes with slowing down is not as great with a design like the FPB 97, as a more trawler like shape because the FPB canoe body has comparatively little wave drag. Without looking up the numbers, dropping from something like 11.5 to ten knots might get you a net of 10/15% better range. If you really wanted to stretch things, and changed props for slower running, and detuned the engines, it might mean 20% gain ay 10 knots.
