I don't think there's much difference if a keel is blown up properly the hull skin is tourt it's the same on both, the good thing about the wood keel is no punctures, fit and forget until the boats stripped down end of season for a clean out sand & debris

That makes sense Jeff.

Never assembled a rigid keel but gut feel tells me it may be more of a pig to get the stringers in. Often not that easy even with a sausage keel, but at least itís not inflated and tensioning the floor while battling with those pesky stringers. Ouch!

Obviously not such a problem if keeping inflated per season.

Liking your link re. 7m Excel Vanguard. What a brute.

Must be a market there for those offering clandestine channel crossings for paying guests!

there's a vid on youtube fitting the keel on a c3 or 4 doesn't seem to be that bad i do like the idea of it though.
yes nice big boat that, i will reserve my comment on the channel crossers but the vanguard would be a lot safer that some they are using

If I was keeping a larger SIB on a trailer I'd prefer the wooden keel... its downside is the faff of assembly on a daily setup craft. But if that's not an issue and you look at the underside of a fully inflated Bombard with the wooden keel... as its contact point with the hull fabric is narrower and more rigid it tightens the underside into a lovely sharp V (for a SIB).

I could imagine it would negate some of the floppy banana effect too.

I found my Zodiac Futura mk2 for $3800. It was new dealer floor model that was 5 yrs old but unused. Just inflated in a showroom. Full warranty. I just happened to ask and they thought about it and decided to let it go.
Pure luck!

That Bombard Commando C5 from Defender is a good price and great quality.

The rigid keel is great. One of the main causes of poor SIB performance is an under inflated keel. By having a rigid keel, it eliminates that problem.

The only complaint is it squeaks a bit if you have a quiet outboard.

How can a rigid keel prevent a fabric puncture? As i understood the design - the fabric is only to add a rigid member under the fabric in place of the inflatable keel.

They do indeed seem to be reasonably priced - and a few good deals to be had. Are there any performance testing data sets available as it may relate to the different inflatable keels and the rigid keel designs?

EXCEL VANGUARD XHD705 Inflatable Boat.
Nice suggestion, not bad on the prices - Im wondering if the company ever runs specials or sales on their inflatables.
