Advice for a potential rib upgrade (Solent use)

Good afternoon,

Just over a year ago, I bought a 2008 Avon 560 rib with a Yamaha 115 4 stroke of the same age, as my first rib.

We do a lot of sailing out of Hamble and the rib was bought largely for fun - wakeboarding with friends, popping over/up the river for dinner, the odd trip over to Cowes/Prior Bay etc or a bit of sea swimming out of Osborne Bay. It's been great so far and I have upgraded it substantially in terms of electronics/nav kit/stereo/proper custom stainless A frame with tow point etc.

On a fair weather day it is a quick, very economical rib, that can comfortably plane with 8/9 people at c28 knots and is great for wakeboarding (after I reduced the prop pitch from 21-19).

Most of the time that we use it is nice weather, but we do find ourselves on occasion out in less nice weather - ie this Cowes Week we had a prizegiving to go over for and we also had day when we needed to drop some sails to Cowes for a repair in 25 knots of breeze. It's a pretty average rib in those conditions. I also found myself in Priory Bay in early July needing to head back in wind over tide and high teens wind, it was a reasonably tough trip to Hamble.

I'm not sure whether to keep the rib and enjoy it for what it's good for, accepting that occasionally it will be a bit of a tough ride (albeit capable of getting through with a fair bit of slamming/spray) or whether to go for something a bit more capable in the heavy weather.

I am open to ideas, would something of similar length, say a smidge longer at c6m Ribeye but with a deeper v be substantially better, or would I need a longer, say 7m+ rib to make the upgrade worthwhile? I don't want to make the change for the sake of making the change and end up with something only a little better, given we have customised the rib to exactly what we want in terms of electronics, a frame etc, but if I can substantially improve the bad weather handling, it would be good.

I also don't want to get into the arms race of much longer, much heavier, much bigger engine, where I am less tempted to go for a spin because I know its going to use a considerable amount of fuel. At the moment I can do Hamble to Cowes and back, or a wakeboarding session on 20ltrs, which is very acceptable and means the rib gets a lot of use.

Really appreciate thoughts and suggestions.

Thank you in advance.

Ribcraft 585 (often coupled with a 140) would do a decent job....and definatly have more capability when/if you did need it for any reason
All those Bods on Board is asking for/courting trouble though IMO.

Thanks Maximus.

What should you pay for one of those? Have there been any design changes over the years?

We very very rarely travel with that many, like twice in owning, usually 2-5 people.

The Solent chop particularly when it is wind against tide is pretty unpleasant in any smallish boat as the seas are so steep.

More deadrise will help along with size but then there is a power / speed penalty for doing this. A deeper forefoot will help to part the waves but at the expense of a bit of bow steer when you are going down waves.

The other route to better seakeeping and this is said with all due respect is how the boat is driven in poor conditions. You might find investing a few hundred quid on a course turns out to be a worthwhile investment as you can deal with the conditions in your current boat. Just to re-iterate, this isn't meant as any criticism.

Scorpion ribs 7.5m -8.5m are great in the solent chop and look the part as well ,just try finding one now as they are hard to find due to being popular.

Do you/Would you trailer it or keep it afloat? If trailering then how far? IMHO once you get north of 7m or so trailering any sort of distance is going to be a pain in the hoop. Fine for special occasions, but it's going to cause you to think twice about 'throwing it in for a quick blast.' (Cue lots of folk with 8m Scorpions saying it's fine)

Dan Gurney has the right boat/engine for the OP, IMO!

Absolutely legend combo. Maybe even better with a Merc 150

I find with my 9m rig (not Scorpion!) that trailing distances are absolutely fine - it's long but very steady, and tows like a dream for hour on end. But absolutely agreed on short distances - it's a right pain and faff to get it all ready and rigged to tow just to do the 500m to the yacht club to drop it in the water for a quick spin! And then to have to recover it at the end again…

In a few weeks mine will be going to live, on it's trailer, at the yacht club, when then just dropping it in the water should be much more pleasant (I hope).

Also: you say you also sail... Does that mean this is not your primary money pit? Given that you've got this Avon just how you like it (And you aren't going to get that time/money back) is it really worth sinking a load of extra into another second hand boat?

To answer your original question though... we went from a 1993 Humber Attaque 5.3 to a Redbay 6.1. The difference in heavy weather is night and day. The Humber was a great wee boat and felt very safe, but you have to slow down much earlier than in the Redbay. We can easily maintain 20knots in force 5 - 6 for as long as our backs can take it. In fact the only time we can keep up with the big lads is when it's lumpy!
