the next step in dinghy design is, IMO, most keenly needed from the deck up, i.e. the rig and sail/foil area, this will then drive the next gen of hull and make the most of what is already known regarding foils

I still have yet to discover a 12 knot minimum wind in windsurfing, without very specialist kit. Mind you, it's only been 36 years since I started so maybe I'm not experienced enough yet.  Edited by Chris 249 - 24 Apr 14 at 11:03am |

light wind wave sailing is the big one, no wind and a little swell you paddle, light wind and a little swell you rig up.... if I lived near some swell I'd probably get one, but I'm not going to drive 3 hours on a forecast which predicts using one. I guess harbour/inland cruising in sub-planing conditions is the other one.... for windsurfers who are yet to discover that windsurfing really does have a minimum wind threshold of around 12 knots without some very specialist kit. Can I see a benefit in an inflatable version- well yes. Given the choice between a longboard on the deck, or an inflatable SUP in an aft locker, I'd pick the inflatable SUP these days, so oddly enough, for Boat Owners, they make an interesting proposition for marinas and anchorage toys. As for inflatable sailboats.... no thanks, not for me.

So far, the price seems to be higher by a factor of at least 2 over what I'd expect for a blow up boat. A long way to go on this, I think.

Don't ask me to sell you SUP it's the most pointless exercise I've come across to date except maybe in poor Surf conditions and there is no grass to watch growing.
As to the USP of the inflatable tech, it's purely storage, price and convenience rather than weight, personally given a choice of a boat made of this stuff or roto/blow moulded polyethylene I'd take the blow up anytime. They'll be coming I'm sure of that with the volume production of SUP bringing the price down, the first generation has already spawned stuff like This so there are bound to be more, the question is how sophisticated rather than beach fodder they become.

Weight saving vs high tech, sure no contest. But what about weight saving vs thermoplastic rotomould? That construction doesn't seem to scale well weight wise into the 15, 16ft size range. Might there be any potential there? |

What pressure are the SUP's (an other inflatable devices) inflated to, and is this done off a hand pump?

What could possibly go wrong?

The Bombard AeroTec Inflatable has been using this tech for at least 15 years in it's floor. Mine is that old. Your thinking is floored if you think it would be a lighter dinghy construction method. You are a stitching together a skin of heavy rubberised cloth then adding the weight of the drop stitched threads. With no appreciable weigh saving. Adding heavy metal values as well as adding the requirement to strengthen specific sites to terminate spars and fittings with self supporting structures which will be heavier than conventional methods. Easy of storage is the only relevant design concept behind small inflatables, other than the inherent safety they deliver when applied to RIBS.
If you want to make a lighter boat. Build it out of single skin Pre-Preg Nomex, Autoclave it and be done with it. |
