A couple of newbie questions....

I'm thinking of getting a 4 metre 'heavy duty' SIB, with aluminium floor. Is it okay to be trailing it around with a 25hp engine on the back? On a RIB the transom is integral to something a lot more structural; would the loads on the engine in transit affect the bonding of the transom to the tubes?

Now for afloat.......... SIBs look great on flattish water; would you take it on the Solent in a 20 knot breeze?

Thanks

Gareth

I have a Mercury 365 hd with a 25hp Suzuki on it and trailer every where with no probs just make sure you have the transom supported on the keel and on the tubes. I lift the engine up and put a block of HDPE through the engine mount to support whilst traveling and strap down to prevent movement.
The RNLI use sibs ok they are 5 m boats but they go out in some horrendous seas the limit is expearence and what your prepared to go out in, do a course RYA must be plenty around the Solent and your learning in the water you want to sail in.

Cheers

20kts is a Force 5. In the lee of a shore that might be fine - but I'd say it was going to be fairly horrible in a SIB further offshore.

Why not a rib?

Price really, as well as what seems available.

Is there anywhere other than eBay to look for older bargains?

SIBs are great fun in the waves (ie 20kts) but really for playing about close to shore. You need to take care though and be sensible and watch the weight distribution or you're a snip away from flipping...


Taking a long journey in bad conditions in a SIB is another story and can get very slow, scary, tiring and uncomfortable very quickly.

Check B&O, Apollo Duck, forums, Gumtree, Friday Ads, boatyards, fishing, sailing clubs. eBay is best chance though, check the eBay SIBs spotted topic for examples.

Forums like this and gumtree are good to keep an eye out or put up a wanted ad.

Thanks for the replies. Given I want it to support my son windsurf training in Hayling Bay, I guess it's probably a rib I need. Budget is the challenge there.

Interestingly I'm not sure it is.

Windsurfers tend to go out in conditions where everyone else is coming in! Willk is right that for normal boating 20 kts would not be too much fun in a SIB for long periods. The normal school of thought is rough weather = bigger boat. BUT windsurfs, big waves, close to shore, aren't ideal for big boats.

If it were me, I would be looking at the sort of thing the surf rescue guys use - small, fast, highly manoeuvrable, easy to right if it goes wrong, soft floor if you get thrown about etc...

The engine will do more abuse WOT on the water to the transom than it could ever do on a trailer.
