The white boat below is a boat I designed 7-8 years ago. It was to be built in fabricated polyethylene, a 30 foot jet boat. The material was conducive to classic lines so I made it what I call contemporary-classic styling. A little bit classic but a little bit contemporary. Full on classic styling would reduce the GA options too much hence that decision. I managed to get a small amount of curve at the stern, and I felt it needed to be balanced out with a bit of reverse flare in the bow. That’s when I came up with the multi panel bow flare to create that reverse flare. Constructed in plastic I could build the boat and almost hide the lines used to create the reverse flare. I can obviously do the same with alloy but have never applied it to my DIYNO Kitset Boat range for two reasons. Firstly my hulls don’t tend to dive down the mine like other boats do so the standard flare does the job very well. I can understand putting a lot of flare in the bow if the bow is continually plunged deep into water. The video shows one of my 801 twin hulls in 45 knots of wind. That was the boats maiden voyage and sea trial. Secondly it would obviously create a lot of work to build and the guys building the kits part time don’t want to be building the boat forever. If it offers no performance advantage, then why do it. On small boats the topside panels are usually constructed of one sheet which saves time and money. On large boats the hull is built with multiple sheets welded together so the reverse flare is commonly built into the hull as it has to fabricated from multiple sheets anyway. The renderings show what one of my 801 twins with the multi panel reverse shear would look like. The pictures are the standard 801 Twin boats. Anyway, it is an option if a builder wants it. Note that to smooth it out would require bogging and fairing. Of course, the risk of that is that bog falls out if the panels flex too much. We have all seen the pictures of that! To me if you want to build a boat that looks like a fibreglass boat, build a fibreglass boat. For the figures being quoted on some of these alloy boats, you could actually build a fibreglass boat for the money. It seems to defeat one of the main purposes of building in alloy. It is the most cost-effective way to build a boat. Anyway, if anyone prefers the multi-panel reverse flare let me know. I would be interested to hear some thoughts.
