I had an Ombrine 700 for two years from new with same engine, sold it last Feb to replace with a new Ombrine 801 as the kids are growing at an alarming rate.
The 700 was excellent, the engine did not sound big enough when I bought the boat but it really did a great job even when loaded with family and friends. The only significant modifications I made were to get a local engineer to make me a stainless rail to go around the coaming around the cockpit, it looked great and improved safety for kids no end. I also fitted soundproofing in and around the engine bay and bay cover - this had a dramatic effect on reducing noise levels, well worth an afternoon's work and £100 of materials. It was a very pretty boat which went well and handled bad weather surprisingly well. Hope you enjoy it.
Alymatt,
Thanks for the feedback, mine has the 105 diesel inboard and the first task I wan't to undertake is to soundproff the engine bay. How did you do yours and what material did you use? Is it enough to insulate the cover? Another issue is that I have only 1 battery - this causes me some concern as I see this as a critical weakness, flat battery and I am stranded. I did some postings and investigation and adding a 2nd battery seems quite complicated. I am bending towards a "jumpstarter" that stays charged for 2 years stashed in a locker. Another quick question - the cabin door seems to be stowable forward in the cabin against the the "roof" (sorry about the term but I live in Italy and don't know the English nauti jargon) but I haven't yet figured out the knack of stowing it.
I used sound insulation sheets from Halyard (www.Halyard.eu.com) which were about 1 metre square and about 40mm. The sheets were lead and foam sandwich and easy to cut to size. To stick I used standard contact adhesive applied to both surfaces. I covered the underside of the engine compartment and the adhesive was plenty strong enough without any wire supports to hold it up. I also covered the vertical sides and front of the engine box (just the surfaces that were above the level of the cockpit floor) in the same way and used foil tape from the local chandlers to leave a tidy job. It was very effective.
Re the battery, I never had a problem with the single battery in the two years I had the boat, but I was also concerned about the single battery so I carried a portable starter battery (as you suggest) but never had to use it. An alternative, especially if your battery is coming up for replacement, would be to fit a much higher capacity battery...it would save a lot of complicated wiring etc and provide more security?
As for the cabin door, my 700 was a 2001 model and the cabin door was hinged and folded open so there was no need to remove and store it separately. The arrangement you appear to have is similar to what I had on my previous Ombrine 550. I used to open the large cockpit locker and store it in there on top of my inflatable tender and the fuel tank...not sure if that would work on your Ombrine 700.
Hope this is useful. Hope you enjoy your boat as much as we did, let me know how the modifications go!
